Question

4. Write a 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.)

this program kinda works but i cant figure out why its making more than 100 random numbers

ls) [*] test2.cpp test3.cpp #include<stdio.h> #include<stdlib.h> int main() 4 { int a[14],is for(i=0;i<100; i++){ a[rand()%10]++; 8 } for(i=0; i<10; i++){ 10 printf("%d was made %d times\n",i,a[i]); 11 ] 12 L} BOO vo WN

Answer 1

#include<stdio.h>
#include<stdlib.h>
int main(){
// we should initialize the array with 0's otherwise it will have garbage values
// we need array with 10 elements not 100 elements
   int a[10]={0},i;
   for(i=0;i<100;i++){
       a[rand()%10]++;
   }
   for(i=0;i<10;i++)
       printf("%d -> %d\n",i,a[i]);

}
