Question

Programming language: C NOT c++

Problem 2 (20 points) Both the for loop and the do-while loop can be transformed into a simple while loop. For each of the following examples a) and b), write equivalent code using a while loop instead. double rand_double)( double ret - (double)rand(); return ret/ (RAND MAX 1); int factorial (int n) int for i, ret =1; (i=2; i <= ret *= 1; n; i++) int sample_geometric_rv(double p)l double q return ret; int ne; do q rand_double); jwhile (q - p); return n a) b)

Answer 1

#include<stdio.h>
int factorial(int n){
int i, ret = 1;
i = 2;
while(i <= n){
ret *= i;
i++;
}
return ret;
}
int main() {
int n;
printf("Enter n: \n");
scanf("%d", &n);
printf("Factorial of %d is %d\n", n, factorial(n));
}

null

Part B:

double rand_double(){
double ret = (double)rand();
return ret/ (RAND_MAX + 1);
}
int sample_geometric_rv(double p){
double q;
int n = 0;
q = rand_double();
while(q >= p){
n++;
q = rand_double();
}
return n;
}
