1. C program to find the sum of individual digits of a number
#include<stdio.h>
int main()
{
int i=1,n,r,sum=0,a;
printf( " Enter value of n: ");
scanf("%d",&n);
a=n;
while(n>0)
{
r=n%10;
sum=sum+r;
n=n/10;
}
printf(" Sum of digits of %d = %d ",a,sum);
return 0;
}
2. C program to find the sum of even digits of a number
#include<stdio.h>
int main()
{
int i=1,n,r,sum=0,a;
printf( " Enter value of n: ");
scanf("%d",&n);
a=n;
while(n>0)
{
r=n%10;
if(r%2==0)
sum=sum+r;
n=n/10;
}
printf(" Sum of even digits of %d = %d ",a,sum);
return 0;
}
3. C program to find the sum of odd digits of a number
#include<stdio.h>
int main()
{
int i=1,n,r,sum=0,a;
printf( " Enter value of n: ");
scanf("%d",&n);
a=n;
while(n>0)
{
r=n%10;
if(r%2==1)
sum=sum+r;
n=n/10;
}
printf(" Sum of odd digits of %d = %d ",a,sum);
return 0;
}
4. C program to find the sum of square of individual digits of a number
#include<stdio.h>
int main()
{
int i=1,n,r,sum=0,a;
printf( " Enter value of n: ");
scanf("%d",&n);
a=n;
while(n>0)
{
r=n%10;
sum=sum+r*r;
n=n/10;
}
printf(" Sum of sqaure of digits of %d = %d ",a,sum);
return 0;
}
