Question

how would i change the for loops to while loops in the code below

#include<stdio.h>
#include<stdlib.h>
int main()
{
int seed;
// Taking seed value as input from the user
printf("Enter a seed value (0 to quit): \n");
scanf("%d", &seed);
// Running the loop until user enters 0 to quit
// count array will count frequency of 0 , 1 , 2 ,3
int count[4];
for (int i = 0; i < 4; i++) count[i] = 0;
while (seed != 0)
{
// Passing seed value to the function srand()
srand(seed);
// Printing 5 random values
for (int i = 0; i < 5; i++) {
// generae a random number
// and take it modulo with 4
int rand_num = rand() % 4;
printf("%d ", rand_num);
count[rand_num]++;
}
printf("\n");
// Taking next seed value as input from the user
printf("Enter a seed value (0 to quit): \n");
scanf("%d", &seed);
}
// print count of each element [0-3]
for (int i = 0; i < 4; i++) {
printf("Count of %d = %d\n", i , count[i]);
}

return 0;
}

scanf("%d", &seed);

int count[4];
int i = 0; 
while (i < 4) {
    count[i] = 0;
    i++;
}
while (seed != 0)
