Power function returning incorrect values within the while loop

Question

I have a function power that returns the value of a potentiation receiving the parameters n and p (n^p). Outside the loop while the function returns the correct values, but within the loop function returns incorrect values, follows below the code:

double power(double, int);

int main()
{
    double n;
    int p;

    printf("%.0f\n", power(5, 2)); // aqui retorna o valor correto de 5^2

   while (1)
   {
        printf("Enter n and p (n^p): ");
        scanf("%.0f", &p);
        scanf("%d", &n);

        printf("The pow is: %.0f\n", power(n, p)); // aqui retorna valores incorretos
    }

   return 0;
}

double power(double n, int p)
{
   double pow = 1;
   int i;

for (i = 1; i <= p; i++)
    pow *= n;

   return pow;
}

Answer 1

The main problem is the formatting of scan() wrong, and has nothing to do with the loop. d is for whole, and the double must use lf.

#include <stdio.h>

double power(double n, int p) {
    double pow = 1;
    for (int i = 1; i <= p; i++) pow *= n;
    return pow;
}

int main() {
    printf("%.0f\n", power(5, 2));
    printf("Enter n and p (n^p): ");
    double n;
    int p;
    scanf("%lf", &n);
    scanf("%d", &p);
    printf("The pow is: %.0f\n", power(n, p));
}
