# C Exercises: Find all numbers which are dividing by 7 and the remainder is equal to 2 or 3 between two given integer numbers

## C Basic Declarations and Expressions: Exercise-40 with Solution

Write a C program that finds all integer numbers that divide by 7 and have a remainder of 2 or 3 between two given integers.

**Sample Solution:**

**C Code:**

```
#include <stdio.h>
int main() {
int x, y, temp, i, sum=0;
// Prompt for user input
printf("\nInput the first integer: ");
scanf("%d", &x);
printf("\nInput the second integer: ");
scanf("%d", &y);
// Swap values if x is greater than y
if(x > y) {
temp = y;
y = x;
x = temp;
}
// Iterate through numbers between x and y (exclusive)
for(i = x+1; i < y; i++) {
// Check if the number modulo 7 is 2 or 3
if((i%7) == 2 || (i%7) == 3) {
printf("%d\n", i);
}
}
return 0;
}
```

Sample Output:

Input the first integer: 25 Input the second integer: 45 30 31 37 38 44

**Flowchart:**
