Help?

WHy wont the following work??

#include <iostream.h>
#include <conio.h>

int main()
{
double radius;
const double pi=3.14;
char calc;
cout<<"This program can calculate Surface area and Volume for a sphere. Type in V for Volume calculation or S for Surface area."<<endl;
cin>>calc;
if(calc=="V")
{
cout<<"What is the radius of the sphere?"<<endl;
cin>>radius;
cout<<"The Volume of the sphere is: "<<(4*pi*(radius*radius)/3)<<endl;
}
if(calc=="v")
{
cout<<"What is the radius of the sphere?"<<endl;
cin>>radius;
cout<<"The Volume of the sphere is: "<<(4*pi*(radius*radius*radius)/3)<<endl;
}
if(calc=="S")
{
cout<<"What is the radius of the sphere?"<<endl;
cin>>radius;
cout<<"The Surface area of the sphere is: "<<(4*pi*(radius*radius))<<endl;
}
if(calc=="s")
{
cout<<"What is the radius of the sphere?"<<endl;
cin>>radius;
cout<<"The Surface area of the sphere is: "<<(4*pi*(radius*radius))<<endl;
}
getch();
getch();
return 0;
}

Id appreciate the help

what is the problem ?

Ahh
yes of course... that could be important

Well the compiler wont compile it
this is what happens

[slx47]

i am not sure if this will solve it but try make a varable to hold the volume and stuff like this:

int * pVolume = 0;//pointer
*pVolume= (4*pi*(radius*radius)

something like that!

[Aerials]

how would that help though
the problem seems to be in the IF statement

Here is the fixed version of your code. You must use single quotes rather than double quotes to indicate characters.

#include <iostream.h>
#include <conio.h>

int main()
{
double radius;
const double pi=3.14;
char calc;
cout<<"This program can calculate Surface area and Volume for a sphere. Type in V for Volume calculation or S for Surface area."<<endl;
cin>>calc;
if(calc=='V')
{
cout<<"What is the radius of the sphere?"<<endl;
cin>>radius;
cout<<"The Volume of the sphere is: "<<(4*pi*(radius*radius)/3)<<endl;
}
if(calc=='v')
{
cout<<"What is the radius of the sphere?"<<endl;
cin>>radius;
cout<<"The Volume of the sphere is: "<<(4*pi*(radius*radius*radius)/3)<<endl;
}
if(calc=='S')
{
cout<<"What is the radius of the sphere?"<<endl;
cin>>radius;
cout<<"The Surface area of the sphere is: "<<(4*pi*(radius*radius))<<endl;
}
if(calc=='s')
{
cout<<"What is the radius of the sphere?"<<endl;
cin>>radius;
cout<<"The Surface area of the sphere is: "<<(4*pi*(radius*radius))<<endl;
}
getch();
getch();
return 0;
}

thx
so all i needed was to change the " to '?
