Count digit repetition in number range Posted: 17 May 2013 03:35 AM PDT Q. Write a C program to count the no. of occurences of n's in a given number range. For example: random numbers : 45,78,2,65,489,6,2,6,55,9 find out how many times the digit 2 repeat? 2's digit repeat 2 times. Ans. /*c program to count the no. of occurences of n's in numbers range*/ #include<stdio.h> int main() {  int arr[10],i,num,r,s,c=0;  for(i=1; i<=10; i++)  {   printf("Enter %d number : ",i);   scanf("%d", &arr[i]);  }  printf("\nEnter search number : ");  scanf("%d", &s);  for(i=1; i<=10; i++)  {   num = arr[i];   while(num>=1)   {    r=num%10;    if(r==s)      c++;    num=num/10;   }  }  printf("\nThe digit %d is repeat in entered number is %d times",s,c);  getch();  return 0; } The output of above program would be: Figure: Screen shot for count repeate digit  in number range C program
