# C Exercises: Find out the maximum difference between any two elements

## C Array: Exercise-69 with Solution

Write a program in C to find the maximum difference between any two elements such that the larger element appears after the smaller number.

**Visual Presentation:**

**Sample Solution:**

**C Code:**

```
#include <stdio.h>
// Function to find the maximum difference between two elements in the array
int maxDifference(int arr1[], int n) {
int i;
int min_element = arr1[0]; // Initialize the minimum element as the first element of the array
int diff = arr1[1] - arr1[0]; // Initialize the difference as the difference between the second and first element
for (i = 1; i < n; i++) {
// Check if the difference between the current element and the minimum element is greater than the current difference
if (arr1[i] - min_element > diff) {
diff = arr1[i] - min_element; // Update the difference
printf("The elements which provide maximum difference is: %d, %d\n", min_element, arr1[i]);
}
// Update the minimum element if the current element is smaller than the current minimum element
if (arr1[i] < min_element)
min_element = arr1[i];
}
return diff; // Return the maximum difference
}
int main() {
int arr1[] = { 7, 9, 5, 6, 13, 2 };
int n = sizeof(arr1) / sizeof(arr1[0]);
int i;
// Printing the original array
printf("The given array is : ");
for (i = 0; i < n; i++) {
printf("%d ", arr1[i]);
}
printf("\n");
// Finding and printing the maximum difference between two elements in the array
printf("The Maximum difference between two elements in the array is: %d", maxDifference(arr1, n));
getchar(); // To keep the output screen open
return 0;
}
```

Sample Output:

The given array is : 7 9 5 6 13 2 The elements which provide maximum difference is: 5, 13 The Maximum difference between two elements in the array is: 8

**Flowchart:**

**C Programming Code Editor:**

**Previous:** Write a program in C to return maximum sum such that no two elements are adjacent.

**Next:** Write a program in C to find two numbers that occur odd number of times in an array.
