I use the MinGW 4.1 compiler and run in WinXP.
As for the Q:
I'm wondering what notation I would use to write exponents in C?
An example I'm working on is writing a program that calculates the volume of a sphere. Formula is: 4/3*pi*radius(cubed).
cheers and thanks in advance |

There is no exponent operator in C or C++, instead you can use the pow() function in math.h.
An example of usage:
c: | #include <stdio.h>
#include <math.h>
int main ()
{
printf("%d\n", (int)pow (5. 0, 3. 0)); //returns 5^3
return 0;
} |
