C program to Find Number of Occurrences of given digit in a number

Numbers in C

Normally, when we work with Numbers, we use primitive data types such as int, short, long, float and double, etc. The number data types, their possible values and number ranges have been explained while discussing C Data Types.

Here is source code of the C program to Find Number of Occurrences of given digit in a number. The C program is successfully compiled and run(on Codeblocks) on a Windows system. The program output is also shown in below.

SOURCE CODE : :

/*  C program to Find Number of Occurrences of given digit in a number  */

#include <stdio.h>

int main()
{
    int num,tNum,digit,cnt;
    int rem;

    printf("\nEnter any number :: ");
    scanf("%d",&num);
    printf("\nEnter any digit to Search :: ");
    scanf("%d",&digit);

    cnt=0;
    tNum=num;

    while(tNum>0)
    {
        rem=tNum%10;
        if(rem==digit)
            cnt++;
        tNum/=10;
    }

    printf("\nTotal occurrence of digit [ %d ] in Number [ %d ] is :: [ %d ].\n",digit,num,cnt);

    return 0;
}

OUTPUT : :

/*  C program to Find Number of Occurrences of given digit in a number  */

Enter any number :: 122123221

Enter any digit to Search :: 2

Total occurrence of digit [ 2 ] in Number [ 122123221 ] is :: [ 5 ].

Process returned 0
