main()

{

int i, num, fact = 1;

printf("Enter a number”);

scanf("%d", &num);

for (i = 1; i <= num; i++)

fact = fact * i;

printf("Factorial of %d = %d\n", num, fact);

}

C program to calculate the Power of a Number

main()

{

int i, base,exp, power = 1;

printf("Enter base and exponent ”);

scanf("%d %d", &base, &exp);

for (i = 1; i <= exp; i++)

for(c=1;c<=n;c++)

result=result * c;

return
result;
