    }
 
    
    for(i=0; i<n; i++)
    {

Example 2: c program to find the sum of given number

# include<stdio.h>
int main
{
int number;
int sum=0;
int remainder;
printf("enter a number\n");
scanf("%d",&number);
for(;number!=0;)
{
remainder=number%10;
sum=sum+remainder;
number=number/10;
}
printf("sum of digits=%d",sum);
}
