Write a c program to find highest number in an array. Given an input array, we have to write a code to find highest number in an array.

There are multiple approaches we can use to solve this problem.

i) Find highest number in an array using sorting algorithm.

We can use any sorting algorithm such as Bubble sort, Selection sort, Insertion sort, Quick sort, Merge sort etc. to sort an array. After sorting an array element at n-1 position is highest number in an array.

The time complexity of sorting an array is O(nlogn).

ii) Traverse an array to find highest number in array.

In this approach, first declare a variable highest and assign first element of an array. After that traverse an array, and compare each element of an array with the value of highest. If any element is greater than the highest then assign that value into highest variable.

The time complexity is O(n).

Let's implement the second approach.

C++ program to find largest number in an array

In this programming example, we first take an input array from user. Then we traverse an array to find highest number in an array.

Enter the size of an array( Max 100) 5

Enter array elements

## C Program to Find Highest Number in an Array

In this programming example, we first take an input array from user. Then we traverse an array to find highest number in an array.

#include <stdio.h> int main() { int arr[100], n, i, highest; printf("Enter the size of an array( Max 100) \n"); scanf("%d", &n); printf("Enter array elements \n"); //Take input values for(i = 0; i < n; i++) { scanf("%d", &arr[i]); } //Assign first value highest = arr[0]; //Traverse an array for(i = 0; i < n; i++) { //If any value is greater than highest if(arr[i] > highest) { highest = arr[i]; } } //Print largest number printf("Largest number is %d ", highest); return 0; }

**Output**:Enter the size of an array( Max 100) 5

Enter array elements
