Question

1. Write a C program that generates one hundred random integers between 0 and 9 and displays the count for each number. (Hint: Use rand()%10 to generate a random integer between 0 and 9. Use an array of ten integers, say counts, to store the counts for the number of 0’s, 1’s,…..,9’s.)

Answer 1

//C program

#include<stdio.h>
#include<stdlib.h>
#include<time.h>

int main(){
   srand(time(NULL));
  
   int counts[10];
   int i;
  
   for(i=0;i<10;i++)counts[i] = 0;
  
   for(i=0;i<100;i++){
       counts[rand()%10]++;
   }
  
   for(i=0;i<10;i++){
       printf("Count of %d = %d\n",i,counts[i]);
   }
   return 0;
}
