Using if condition and while loop in C get a number of input from the keyboard and calculate the sum of odd and even digits separately?

Answer 1

#include<stdio.h>

#include<conio.h>

void main()

{

int num,num_save;

int ar[5],i=0,res_e=0,res_o=0;

printf("\nEnter the number : ");

scanf("%d",&num);

num_save=num;

while(num_save>0)

{

ar[i]=num_save%10;

num_save/=10;

i++;

}

i--;

while(i>=0)

{

if(ar[i]%2==0)

res_e=res_e+ar[i];

else

res_o=res_o+ar[i];

}

printf("\nNumber is %d\n",num);

printf("\nSum of even digits is %d",sum_e);

printf("\nSum of odd digits is %d",sum_o);

getch();

}
