You are using the forumula incorrectly
you can check this code prints 4.41 if you want:

Code:
#include <math.h>
#include <stdio.h>
#define P 1.0   //principal = $1.00
#define N 10.0  // number of years = 10
#define I .16   // annual interest rate 16% -- ie., 16/100
#define Q 1.0  // number of payments per year
// this prints 4.41
int main(){
    double A;
    A = P* pow((1+ (I/Q)), N * Q);
    printf("total= %f\n",A);
    return 0;
}
Amount = $1.00 * ( 1 + (.16/1)) 10*1
