    strange error int

    here is my code

    Code:
    #include <stdio.h>
    #include "genlib.h"
    #include "simpio.h"
    #define pi 3.14
    int main() {
    string whatShape;
    printf("enter the shape: ");
    whatShape = GetLine();
    if (whatShape == "box") 
    {
    	int width, length, height, ansr;
    	printf("enter width: ");
    	width = GetInteger();
    	printf("enter height: ");
    	height = GetInteger;
    	printf("enter length: ");
    	length = GetInteger;
    	ansr = height * length * width;
    	printf("The voulme of the box is: %d ", ansr);
    }
    if (whatShape == "cube") 
    {
    	int side, ansr;
    	printf("enter the length of a side: ");
    	side = GetInteger();
    	ansr = side * side * side;
    	printf("The volume of the cube is: %d", ansr);
    }
    if (whatShape == "cylinder") 
    {
    	double radius, radiussquared, height, ansr;
    	printf("enter the height: ");
    	height = GetInteger();
    	height = (double)height;
    	printf("enter the radius: ");
    	radius = GetInteger();
    	radiussquared = radius * radius;
    	radiussquared = (double)radiussquared;
    	ansr = radiussquared * height * pi;
    	printf("The volume of the cylinder is: %d", ansr);
    }
    else printf("that is not a box, cude, or cylinder");
    }
    error
    Code:
    : error C2440: '=' : cannot convert from 'int (__cdecl *)(void)' to 'int'
            There is no context in which this conversion is possible
    i have no idea what to do to fix this, any help would be greatly appreciated

    now i have worked it out a little but im getting a strange error here:
    Code:
    if (StringEqual(whatShape, "cylinder")) 
    {
    	double radius, radiussquared, height, ansr, pi;
    	int radius1, height1;
    	pi = 3.14;
    	printf("enter the height: ");
    	height1 = GetInteger();
    	height = (double)height1;
    	printf("enter the radius: ");
    	radius1 = GetInteger();
    	radius = (double)radius1;
    	radiussquared = radius * radius;
    	radiussquared = (double)radiussquared;
    	ansr = radiussquared * height * pi;
    	printf("The volume of the cylinder is: %d\n", ansr);
    }
    with height 3 and radius 3 i get this answer: -2061584302

    Use &#37;f to print a double (or a float).

    > radiussquared = (double)radiussquared;
    It's already a double, are you just making sure?
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.

    Don't use printf; use cout.

    Is it C++, or merely just C code posted on the C++ forum?

    Right. I saw "string" in there, but it is apparently C since <string> has not been included, so I'm assuming it is a typedef for char.
    But then again, maybe one of those headers include it because the error message is typical C++-ish...
    So that's a very good question.

    Yeah, could have been either with
    if (whatShape == "cylinder")

    but then
    if (StringEqual(whatShape, "cylinder"))
    showed up and tipped the balance back towards C.

    Hrm...
    Then how about you replace all the printf-s with cout and post a complete list of errors?
    If there are any left, that is.

    And you probably should add "using namespace std;" or qualify string and cout with std::.
