In function âstd::string infixToPostfix(const std::string&)â:
error: âprecedenceâ was not declared in this scope

HERE IS THE CODE

class ConvInfPost
{
public:
ConvInfPost() //Constructor
{
}

int precedence(char op);

string infixToPostfix(const string& infixExp);

double evaluatePostfix(const string& postfixExp);

// int Result;
};
HERE THE LINE OF ERROR?HOW YOU CAN SEE IS DECLARED IN THE CLASS

while (!aStack.isEmpty() &&
top != '(' &&
precedence(ch) <= precedence(top))
{
postfixExp += top;
aStack.pop(top);
if (!aStack.isEmpty())
aStack.peek(top);
}// end while

Is there more code? If there is post it.

btw Use code tags when posting code. It's much easier to see. (Hit the picture that looks like a # sign and place your code inside the tags)

I can see that you're calling the function. I don't see the definition.
If the definition is in a different file, you'll need to add it to the compilation process so that the linker can link them.

Is the bolded line of code inside one of ConvInfPost's member functions?
