Lead Number

Lead Number is a number whose sum of even digits is equal to the sum of odd digits.

Example 1: 143. Sum of even digits = 4 = 1+3 = Sum of odd digits. Hence it is a Lead Number.

Example 2: 234. Sum of even digits = 2+4 ≠ 3 = Sum of odd digits. hence it is not a Lead Number.

C
#include <stdio.h>
int main()
{
    int n=0,r=0,oSum=0,eSum=0,nCopy=0;
    printf("Enter a number: ");
    scanf("%d", &n);
    nCopy=n;
    while(n>0)
    {
        r=n%10;
        if(r%2==0)
        {
            eSum=eSum +r;
        }
        else
        {
            oSum=oSum +r;
        }
        n=n/10;
    }
    if(eSum==oSum)
    {
        printf("%d is a Lead Number",nCopy);
    }
    else
    {
        printf("%d is not a Lead Number",nCopy);
    }
    return 0;
