# C Exercises: Find the maximum element in an array which is first increasing and then decreasing

## C Array: Exercise-87 with Solution

Write a program in C to find the maximum element in an array that is first increasing and then decreasing.

**Sample Solution:**

**C Code:**

```
#include <stdio.h>
// Function to find the maximum element in an array that increases then decreases
int firstIncreDecre(int arr1[], int n)
{
int max_ele = arr1[0]; // Initialize the maximum element as the first element
// Loop through the array to find the maximum element
for (int i = 1; i < n; i++)
{
if (arr1[i] > max_ele)
max_ele = arr1[i]; // Update max_ele if a greater element is found
}
return max_ele; // Return the maximum element
}
int main()
{
int arr1[] = {2, 7, 12, 25, 4, 57, 27, 44}; // Fill the array by increasing and decreasing elements
int n = sizeof(arr1) / sizeof(arr1[0]);
int i;
// Print the original array
printf("The given array is: \n");
for (i = 0; i < n; i++)
{
printf("%d ", arr1[i]);
}
printf("\n");
// Find and print the maximum element which increases then decreases
printf("The maximum element which is increasing then decreasing is: %d ", firstIncreDecre(arr1, n));
return 0;
}
```

Sample Output:

The given array is: 2 7 12 25 4 57 27 44 The maximum element which is increasing then decreasing is: 57
