Full Discussion: power function in C
Top Forums Programming power function in C Post 9614 by guru on Tuesday 30th of October 2001 11:11:42 PM

hey, just like shaik said, i would also use pow(). but if you are dying to have your own here is a simple prog.

main()
{
int i;
int a=2; //you can choose any value for a and b
int b=3;

int c=a;

for(i=0;i<b-1;i++){
c*=a;
}
printf("%d",c);
}

also, if you do cc -o t1 t1.c, then your binary is gonna be t1. if you just do cc t1.c, then your binary is a.out (default)
