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:

it can also be done without array
ReplyDeleteHi Did you write c program for numerology calculator
