C program to calculate the power of a number

PROGRAM-1:

Power of a number using while loop

#include <stdio.h>
int main()
{
    int base, exponent;

    long long result = 1;

    printf("Enter a base number: ");
    scanf("%d", &base);

    printf("Enter an exponent: ");
    scanf("%d", &exponent);

    while (exponent != 0)
    {
        result *= base;
        --exponent;
    }

    printf("Answer = %lld", result);

    return 0;
}

OUTPUT:

Enter a base number: 3
Enter an exponent: 4
Answer = 81

PROGRAM-2:

Power using pow() function

#include <stdio.h>
#include <math.h>

int main()
{
    double base, exponent, result;

    printf("Enter a base number: ");
    scanf("%lf", &base);

    printf("Enter an exponent: ");
    scanf("%lf", &exponent);

    
    result = pow(base, exponent);

    printf("%.1lf^%.1lf = %.2lf", base, exponent, result);

    return 0;
}

OUTPUT:

Enter a base number: 2.3
Enter an exponent: 4.5
2.3^4.5 = 42.44
