void value not ignored as it ought to be

The error message "void value not ignored as it ought to be" typically occurs in C++ when you attempt to use the result of a function that returns a void type. In C++, void means that the function doesn't return a value.

Here's an explanation of each step:

1. Identify the Function: First, identify the specific function call that is causing the error. Look for a line of code where you're calling a function.

2. Check the Function's Return Type: Verify the return type of the function you're calling. In this case, the error message is indicating that the function returns void, which means it doesn't return any value.

3. Check How You're Using the Result: Examine the line of code where you're using the function's result. Ensure that you're not trying to assign or use the result as if it were a value, as you can't do that with a void function.

4. Fix the Code: To resolve this error, you should modify your code to either use the function's return value correctly if it returns a value other than void, or if the function is intended to perform some action without returning a value, make sure you're not trying to use its result in an assignment or expression.

Here's an example of code that would trigger this error:

void myFunction() {
    // Some code here
}

int main() {
    int result = myFunction(); // Error: void value not ignored as it ought to be
    return 0;
}

In this example, myFunction is a void function, and you're trying to assign its result to the result variable, which is not allowed. To fix it, remove the assignment or make sure you're using the function correctly based on its intended purpose.
