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>

int firstIncreDecre(int arr1[], int n)
{
   int max_ele = arr1[0];
   for (int i = 1; i < n; i++)
   {
       if (arr1[i] > max_ele)
          max_ele = arr1[i];
   }
   return max_ele;
}
 
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 original array ------------------	
	printf("The given array is:  \n");
	for(i = 0; i < n; i++)
		{
			printf("%d  ", arr1[i]);
		}
	printf("\n");
//-----------------------------------------------------------	   
   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
