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)
