hello everyone I'm having problems with my program. It is supposed to take two numbers and raise on to the other, but when I try to compile the program I get.
In function 'power':
error: macro "pow" passed 3 arguments, but takes just 2
thanks for any help given.
#include <stdio.h>
#include <tgmath.h>
int main(void)
{
int x,n;
printf("insert number: ");
scanf("%d",&x);
printf("insert number to raise previous number to: ");
scanf("%d",&n);
int power(a10)
{
printf("Value %d ^ %d = %f", pow(x, n,));
}
}
