Error expected initializer before int

You forgot a ; in line 4 of your code dude! (In the image you posted.)

Actually there is no need of line 4: int lsearch(int [], int, int). Because in the next line you are defining the function itself. You can skip the prototype declaration if you wish.

And from next time please post proper code, not just an image. And by code I mean actual code that is causing error. Here the code in your image is different from the one which you have typed in your post!

In your typed code you are calling lsearch as lsearch(arr[], N, ITEM) [line 34]. A call should be made like this: lsearch(arr, N, ITEM).

Here is you corrected code:

#include <iostream>
using namespace std;

int lsearch(int [], int, int);

int main() {
    int N, ITEM, INDEX, ar[20];
    cout << "How many elements? (max 20): " << endl;
    cin >> N;
    cout << "Enter elements: " << endl;
    for (int i = 0; i < N; i++)
        cin >> ar[i];
    cout << "Your array is as follows: " << endl;
    for (int i = 0; i < N; i++)
        cout << ar[i] << endl;
    cout << "Enter the element to be searched for: " << endl;
    cin >> ITEM;
    INDEX = lsearch(ar, N, ITEM);
    if (INDEX == -1)
        cout << "Element not found!" << endl;
    else
        cout << "Item found at index: " << INDEX << " position: " << INDEX + 1 << endl;
    return 0;
}

int lsearch(int ar[], int N, int ITEM) {
    for (int i = 0; i < N; i++)
        if (ar[i] == ITEM)
            return i;
    return -1;
}

Sample Run:

How many elements? (max 20): 5
Enter elements: 1 2 3 4 5
Your array is as follows: 
1
2
3
4
5
Enter the element to be searched for: 4
Item found at index: 3 position: 4

This code is practically the same (I guessed this code from your image):

#include <iostream>
using namespace std;

int lsearch(int[], int, int); // Your line 4 which isn't necessary and where you missed a semi-colon!
int lsearch(int ar[], int N, int ITEM) {
    for (int i = 0; i < N; i++)
        if (ar[i] == ITEM)
            return i;
    return -1;
}

int main() {
    // same as in above code
}

You should also check out this thread on why «using namespace std» is considered a bad practice.

Error expected initializer before cin

I’m writing a class with an array and I’m supposed to calculate the average of some entered grades outside the class and in the main but I get the error
Expected Initializer before ‘.’ token

I’m not to sure what to do or i even did the class right
Please help!

What if I promised you $1000, but then just walk away, leaving you empty handed?
You make a promise on line 24, but you don’t keep it.

The error is on line 44. Please explain this code:
float gradeAverage.getGrade();

Line 44 looks like a nice prototype, but what is it doing in the middle of the program?

In the function «getGrade()» Why are you printing the array when you should be returning something from the array. In this case the «getGrade()» function should have a parameter the represents the element of the array that you need.

As you have it «float getGrade ()» would be better named «void printGrades ()».

Hope that helps,

I know that i shouldn’t be printing the there but the question was my teacher gave me was this
Write a class called Student that contains a property called grades that can store a
maximum of 10 grades. Create a setter and a getter method. The setter method
will take no parameters and return no parameters. Instead, within the setter
method you must construct a loop that will ask the user to enter 10 grades. The
getter method will simply print the 10 grades; so, it will take no and return no
parameters. Yes, that is a misnomer; this is because passing and returning arrays
has not been covered yet. Create another method called computeAverage that
return the average of all the grades. Create another method called
minimumGrade that returns the minimum grade the student received.

He knows it’s a misnomer but he wants us to do it anyway.
He hasn’t covered it yet so I was just looking it up but nothing I find helps

Now that I see what is required I will take a look tomorrow and see what I can do.

You do have something essential missing, the braces around the body of the function.

Once you have followed that advice you will get a different error: What is the «again»?

When I put a brace < before the while statement I end up with a 10 more errors?
This is my first programming class I have never done anything like this and I’m frustrated.

These are the instruction for the program, I have to include all of this and I don’t even know if I have included all of it.

Create the following program which converts Fahrenheit to Celsius. Your program must have the following functions:
•Read integer Fahrenheit temperatures from the user. You need to check whether the input is the correct one or not. If the user enters the incorrect number, ask it again.
•Use the formula: Celsius = (Fahrenheit – 32) * 5.0 / 9.0
•The output Celsius should be a floating point with two digits of precision.
•The Celsius temperatures should be displayed with a sign of positive or negative.
•The program should ask the user to continue or not. If the user wants to do the conversion again, use repetitive statements such as DO WHILE, FOR, or IF THEN ELSE to do the conversion again.
•Add comments to explain the functions of the program.

I have been working on this and this is what I now have, with a set of new errors.
which are [Error] ‘setprecision’ cannot be used as a function
and [Error] ‘setw’ cannot be used as a function

Hi dreaweiss, welcome to the forum.

I’ll outline the problems with your code:

1.) On line 4, you declare three variables. Two of them, namely ‘setprecision’ and ‘setw’ are also the names of functions found in the ‘std’ namespace. Normally, one would access these functions by using the scope-resolution operator like so: std::setprecision and std::setw . However, since you’ve elected to use using namespace std; in global scope, the compiler thinks that your function calls on lines 28 and 30 are actually attempts to treat your variables on line 4 as functions.

The way to fix this is to simply remove the offending variables on line 4, since you aren’t even using them for anything. Your fourth line of code should therefore only declare ‘again’.

2.) Technically, line 4 shouldn’t just declare ‘again’, but also define / initialize it. If you do not give ‘again’ an initial value, you’re invoking undefined behavior on line 5 when you enter the while-loop because ‘again’ contains garbage, and you’re attempting to access it. Fix this by initializing ‘again’ on line 4 (so that it may enter the while-loop).

In addition, ‘again’ shouldn’t be an int , it should be a char .

3.) There’s a discrepancy in the condition of your while-loop on line 5. What you probably meant to write was while (again == ‘y’ || again == ‘Y’ ) , not while (again == ‘Y’ || again == ‘Y’ ) .

4.) The while-loop on line 5 has no body. The semi-colon (‘;’) immediately following the parentheses on line 5 is the cause of this. You will have to remove the semi-colon and add some braces (‘<‘ and ‘>‘) around all of the code that should be part of the while-loop’s body.

That should be a good start. I’ve appended this basic code as a guide:

Xismn,
Thank you
I followed all of your directions, I no longer have any errors in my code but when I run it the black boxes opens and nothing is in it. It should be asking for a Fahrenheit degree and then give it to me Celsius, and then ask if I want to convert more values. I don’t know where to go from here, with no errors showing up
This is what have now

You have extra braces.

You will find it extremely helpful to
1. Indent your code consistently. Use an editor which does this for you.
2. Type the closing brace at the same type you type the opening brace. Use an editor which does this for you.

Here is a «fixed» version. (there’s still some issues, but it will compile with warnings.)

i run your program but then i see this issue it will be helpful if i get perfectly running program so that i know for my upcoming exam how to make this type of program run. I am currently preparing for my exam. hope to see some help from you guys out there

This line :

Should be :

thank you for the help but why am i facing problem like this?

Notice that the compiler provides you with the location of any errors that it encounters.

Line 9, column 26 — usually there’s a filename, too. There’s a missing comma (I missed it, apologies.)

If the problem is a syntax error, the compiler will report the error no earlier than it appears. Look at the location of the first error and then look backwards towards the beginning of the file until you find it.

thank you for the help its so much appreciated and helpful for my upcoming exam and future programming errors. but can you help me with my issue on line 41?
