C Exercises: Find the number and sum of all integer between 100 and 200, divisible by 9

C For Loop: Exercise-39 with Solution

Write a program in C to find the number and sum of all integers between 100 and 200 which are divisible by 9.

Visual Presentation:

C Code:

#include <stdio.h> // Include the standard input/output header file.

int main()
{
   int i, sum=0; // Declare variables for iteration and sum.

   printf("Numbers between 100 and 200, divisible by 9 : \n"); // Print a message to indicate the output format.

   for(i=101; i<200; i++) // Loop through numbers from 101 to 199.
   {
     if(i%9==0) // Check if the current number is divisible by 9.
     {
       printf("% 5d", i); // Print the number with formatting.
       sum += i; // Add the divisible number to the sum.
     }
   }

   printf("\n\nThe sum : %d \n", sum); // Print the total sum of divisible numbers.
    return 0;  // Indicate that the program has executed successfully.
}

Sample Output:

Numbers between 100 and 200, divisible by 9 :                                                                 
  108  117  126  135  144  153  162  171  180  189  198
