Number of digits

int main()

{
int c=0;
int i=3856;

int l=i; while(l>0)

{
l=l/10;

c++;

} printf("%d",c);

return 0; }

Summation of digits

int main()

{
int sum=0; int i=384;

int l=i; while(l>0) {

sum+=l%10; l=l/10;
}

printf("%d",sum);

return 0; }

 

 

Alice likes to create new definitions for various mathematical facts. She has, therefore, recently defined equality of two numbers as below: Two integer numbers are equal if they have the same number of digits, and the summation of their digits are equal. For instance, 21 is not equal to 201, because although the sums of their digits are equal (either of them sums to 3), they have different lengths. However, 21 is equal to 30, because they have the same length and sum to the same number, 3. As two more examples, 741 is equal to 525, but 953 is not equal to 9152. Write a C program that repeatedly receives two integer numbers as inputs, compares them and prints out their equality based on Alice's definition of equality. At the end of the loop, the user can decide to try again or to exit. For simplicity, you can assume that the user only enters positive numbers. Sample execution: Please enter the first integer number: 3285 Please enter the second integer number: 3591 Numbers are equal. Do you want to try again? (1/yes, 0/no)1 Please enter the first integer number: 305 Please enter the second integer number: 4121 Numbers have different length. Do you want to try again? (1/yes, 0/no)1 Please enter the first integer number: 210 Please enter the second integer number: 220 Numbers are not equal. Do you want to try again? (1/yes, 0/no) 1 Please enter the first integer number: 400 Please enter the second integer number: 301 Numbers are equal. Do you want to try again? (1/yes, 0/no) 0 Goodbye!
