Didn’t you get a line number with the error message? Or does your system expect you to be a mindreader?

The error line is 243

..

my apologies the brace is in my program , i just missed it out here.. will enter it in now… but my errors still remains on the last line

I just had a quick look at your code using the shell and also what you presneted here.

You have a series of stuff ups with braces etc and you will need to:
1. Properly present your code professionally especially using proper indentation.
2. Line 241 is rubbish that does nothing. Get rid of it.
3. Make sure all braces balance.

You’re in for some fairly easy editing and debugging if you do that and if you understand the code you’re using.

привыкайте нормально код форматировать. черт ногу сломит в такой писанине.
по ошибке: если это студия и в начале файла нет #include «stdafx.h» — то в этом может быть причина.
может есть другой код, который вы не написали тут, но он есть. например тут нед вообще ни
одного инклуда, что там у вас еще есть, чего вы не запостили известно только вам.

Во-первых, если операция только одна, то операторные скобки необязательны (хотя бы не запутаетесь)
Во-вторых, так как Вы не привели полный код программы, откуда нам знать, что эта ошибка не возникает во всяких подпрограммах типа zapr_menu()?

вот полный код программы, выдает ошибку в последней строке, пробовала убирать частично код программы, ошибка уходит, если только убрать строки #include «teoria.h» и #include «teoria.cpp, выходит ошибка в них

#include «teoria.cpp»

что значит #include исходный код C++? Вы подключаете и хедер teoria.h и исходник teoria.cpp

нормально форматируйте не только тут на форуме, но и у себя в редакторе и такого рода проблем будет на порядок меньше.

It appears that your code is just missing some closing braces. That’s all.

For example, look at this:

  operate=infix[i];
  {
  if(mystack.empty() || precedence(operate)>= precedence(mystack.top()))
  {
    mystack.push(operate);           

   else
   {
    while(precedence(operate)<= precedence(mystack.top()))

Where is the closing } before the else statement. Just go through your code and fix these silly mistakes.

It would be a lot easier to rid yourself of these things if you made your spacing and indentation a little neater.

The «expected primary expression before else» diagnostic is the compiler-author’s way of reporting you rudely foisted on him an «else» without either a preceding «if» or (what amounts to the same thing) «else if». Alexander Rafferty correctly points out that this is because the code has …

if (condition) {
  // ...
  else { }

… when perhaps what you meant was …

if (condition) {
   // ...
}
else {
}

… though maybe you deleted a whole bunch of stuff by accident, and were lucky enough that the deletion resulted in unparseable code, so you will realize that something is wrong.

Look at these lines:

if(mystack.empty() || precedence(operate)>= precedence(mystack.top()))
{
   mystack.push(operate);           

else

    заранее спасибо!!!

    Последнее редактирование: 23 мар 2018

  2. Дважды
    void loop объявлена
    И внутри первой loop торчит объявление void setup.

    Разберите внимательно всю эту кашу. И читайте что говорит компилятор.

  4. Убрать лишнее объявление
    void loop().
    И не повторять эту ошибку.

  5. После функции

    bool _isTimer(unsigned long startTime, unsigned long period )
    {
      unsigned long currentTime;
      currentTime = millis();
      if (currentTime>= startTime)
      {
        return (currentTime>=(startTime + period));
      } else
      {
        return (currentTime >=(4294967295—startTime+period));
      }
    }
     

    Идёт ещё какой то код.

    Такое ощущение что ты втыкал куски кода куда попало.

  6. а тут что ??????

How to fix expected primary expression beforeThe expected primary expression before occurs due to syntax errors. It usually has a character or a keyword at the end that clarifies the cause. Here you’ll get access to the most common syntax mistakes that throw the same error.

Why Does the Expected Primary Expression Before Occur?

The expected primary expression before error occurs when your code doesn’t follow the correct syntax. The mistakes pointed out below are the ones that often take place when you are new to programming. However, a programmer in hurry might make the same mistakes.

So, here you go:

– You Are Specifying the Data Type With Function Argument

If your function call contains the data type along with the argument, then you’ll get an error.

Here is the problematic function call:

int addFunction(int num1, int num2)
{
int sum;
sum = num1 + num2;
return sum;
}
int main()
{
int result = addFunction(int 20, int 30);
}

– The Wrong Type of Arguments

Passing the wrong types of arguments can result in the same error. You can not pass a string to a function that accepts an argument of int data type.

int main()
{
int result = addFunction(string “cat”, string “kitten”);
}

– Issue With the Curly Braces Resulting in Expected Primary Expression Before }

Missing a curly bracket or adding an extra curly bracket usually results in the mentioned error.

– The Parenthesis Following the If Statement Don’t Contain an Expression

If the parenthesis in front of the if statement doesn’t contain an expression or the result of an expression, then the code won’t run properly. Consequently, you’ll get the stated error.

How To Fix the Given Error?

You can fix the “expected primary-expression before” error by using the solutions given below:

– Remove the Data Type That Precedes the Function Argument

Remove the data type from the parenthesis while calling a function to solve the error. Here is the correct way to call a function:

int main()
{
int result = addFunction(30, 90);
}

– Pass the Arguments of the Expected Data Type

Double-check the function definition and pass the arguments of the type that matches the data type of the parameters. It will ensure that you pass the correct arguments and kick away the error.

– Ensure The Equal Number of Opening and Closing Curly Brackets

Your program must contain an equal number of opening and closing curly brackets. Begin with carefully observing your code to see where you are doing the mistake.

– Add an Expression in the If Statement Parenthesis

The data inside the parenthesis following the if statement should be either an expression or the result of an expression. Even adding either true or false will solve the issue and eliminate the error.

FAQ

You can view latest topics and suggested topics that’ll help you as a new programmer.

– What Does It Mean When the Error Says “Expected Primary Expression Before Int” in C?

The “expected primary expression before int” error means that you are trying to declare a variable of int data type in the wrong location. It mostly happens when you forget to terminate the previous statement and proceed with declaring another variable.

– What Is a Primary Expression in C Language?

A primary expression is the basic element of a complex expression. The identifiers, literals, constants, names, etc are considered primary expressions in the C programming language.

– What Are the Types of Expressions?

The different types of expressions include arithmetic, character, and logical or relational expressions. An arithmetic expression returns an arithmetic value. A character expression gives back a character value. Similarly, a logical value will be the output of a logical or relational expression.

Conclusion

The above error revolves around syntax mistakes and can be solved easily with a little code investigation. The noteworthy points depicting the solutions have been written below to help you out in removing the error:

  • Never mention the data type of parameters while calling a function
  • Ensure that you pass the correct type of arguments to the given function
  • You should not miss a curly bracket or add an extra one
  • The if statement should always be used with the expressions, expression results, true, or false

What is expected primary expression before errorThe more you learn the syntax and practice coding, the more easily you’ll be able to solve the error.
