What is wrong with my program

ok i put the variables as a global variable (if these are global variables)

Code:

float x;
float y;
char a;

float gathering()

and it says that answer is not being initialized.

initialize - definition of initialize by the Free Online Dictionary, Thesaurus and Encyclopedia.

i found the answer, this is my new code

Code:

#include <iostream>
#include <cmath>

using namespace std;
float math()
{
	float x;
    float y;
    char a;
	float answer;
   cout<<"enter an problem (operations are x,/,+,-,^,s2(square root))";
   cin>> x >> a >> y;

	switch (a){
	case 's':
		answer = sqrt (x);
		break;
	case 'x':
		answer = x*y;
		break;
	case '/':
		answer = x/y;
		break;
	case '+':
		answer = x+y;
		break;
	case '-':
		answer = x-y;
		break;
	case '^':
		answer = pow (x,y);
		break;
	}
	return answer;
}

thank you all for the help.

You know, C structs like C++ classes can have constructors and as such, you can pre-initialize the internal variables to known or default values....

Just saying...
