Write the

int main(void)

function as a driver program and call the above

three

functions result with

sample Input/Output.

 1) #include #include int power(int, int); int main(void) { int x, n; printf("Enter a number and powerto raise it to: "); scanf_s("%d %d", &x, &n); printf("Result: %d ", power(n, x)); return 0; } int power(int x, int n) { int m; if (n == 0) return 1; if (n % 2 == 0) { m = power(x, n / 2); return m * m; } else return x * power(x, n - 1); } 

2)

#include  int hcf(int n1, int n2); int main() { int n1, n2; printf("Enter any two positive integers: "); scanf("%d %d", &n1, &n2); printf("Greatest Common Divisor of %d and %d is %d.", n1, n2, hcf(n1,n2)); return 0; } int hcf(int n1, int n2) { if (n2 != 0) return hcf(n2, n1%n2); else return n1; } 

3)

#include  int main() { int array[], minimum, size, c, location = 1; printf("Enter the number of elements in array "); scanf("%d",&size); printf("Enter %d integers ", size); for ( c = 0 ; c < size ; c++ ) scanf("%d", &array[c]); minimum = array[0]; for ( c = 1 ; c < size ; c++ ) { if ( array[c] < minimum ) { minimum = array[c]; location = c+1; } } printf("Minimum element is %d", minimum); return 0; }
