# C Exercises: Find a pair with the given difference

## C Array: Exercise-83 with Solution

Write a program in C to find a pair with the given difference.

Sample Solution:

C Code:

``````#include <stdio.h>
#include <stdbool.h>

// Function to find the pair with the given difference
bool pairFinding(int arr1[], int size, int d) {
int i = 0;
int j = 1;

while (i < size && j < size) {
if (i != j && arr1[j] - arr1[i] == d) {
printf("The pair are: (%d, %d)", arr1[i], arr1[j]); // Print the pair
return true;
} else if (arr1[j] - arr1[i] < d) {
j++; // Increment j to check the next element
} else {
i++; // Increment i to check the next element
}
}

printf("No such pair found in the given array."); // Print if no pair found
return false;
}

int main() {
int arr1[] = {1, 15, 39, 75, 92};
int size = sizeof(arr1) / sizeof(arr1); // Calculate array size
int d = 53;
int i;

// Printing the original array
printf("The given array is:  \n");
for(i = 0; i < size; i++) {
printf("%d  ", arr1[i]);
}
printf("\n");

printf("The given difference is:  %d\n", d);
pairFinding(arr1, size, d); // Function call to find the pair with the given difference
return 0;
}
```
```

Sample Output:

```The given array is:
1  15  39  75  92
The given difference is:  53
The pair are: (39, 92)
```
