This code works for 4 digit number. If you want code that works for any digit, you can tell me. I will give you.

#include <stdio.h>
int main() {
int a,sum;
printf("Enter a number: ");
scanf("%d",&a);
sum=(a/10)%10+(a/100)%10;
printf("Answer: %d",sum);
return 0;
}

Answer 2

The easiest way is to convert the number into an array of characters, take the substring and then find the sum.

Answer 3

i have tried but no use
can you provide me with complete code

Answer 4

If you are sure it is a four digit number then

#include <stdio.h>
/* Function to get sum of digits */
int getSum(int n)
{
int sum;

sum=0;
/* Single line that calculates sum */

sum=sum+(n/100)%10+(n%100)/10;

return sum;
}

// Driver code
int main()
{
int n = 3547;
printf(" %d ", getSum(n));
return 0;
}

Answer 5

Can you suugest me with code

Answer 6

Post your attempt

Answer 7

/* Function to get sum of digits */
int getSum(int n)
{
int sum;

/* Single line that calculates sum */
for (sum = 0; n > 0; sum += n % 10, n /= 10)
;

return sum;
}

// Driver code
int main()
{
int n = 3547;
printf(" %d ", getSum(n));
return 0;
}
