Replace digits Integer C Program

Problem Statement

Write a program to replace X by digits to make the integer divisible by 4

Note: we have to replace x by numbers digit from 0 to 9, so that it will be divisible by 4.

Solution

#include<stdio.h> //For input/output standard function in c program

#include<stdlib.h>

#include<string.h>

int main()

{

    int i;

    char s[100];

    scanf("%s",s);

    for(i='0';i<'9';i++)

    {

        s[strlen(s)-1]=i;

        if(atoi(s)%4==0) //atoi function used to convert string into integer

        printf("%s ",s);

    }

    

}

Input

246X           

Output                                                                                                                  

2460 2464 2468

Input

64474X

Output                                                                                                                           

644740 644744 644748
