﻿ C : Sum of all integers between 100 and 200, divisible by 9

# 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

The sum : 1683
```
