# C program to find the largest element of the given array

In this C Programming example, we will discuss the pseudocode and will implement the program to find the largest element of the given array.

## 1. How to find Largest element of the array?

In this Program, we need to find the largest element in the array and that task can be accomplished by traversing the array from start to end and comparing the first element with all the elements of the array.

For every element, compare it with the first element and if the element is found greater, then update the first element as max.

```Example
Input: 10, 20, 30, 50, 40
Output: The largest element is = 50```

## 2. Pseudocode to find the largest element in an array

Let’s discuss the pseudocode for the program to find the largest element of the given array in C.

We can find the largest element in the array by taking first two elements and considering first element as the largest and start comparing among them and move forward and keep comparing an updating the first element.

```Pseudocode:
Start
Initialize num, arr[]
Initialize largestNumber = arr

for i -> 1 to (num - 1)
if largestNumber < arr[i]
largestNumber = arr[i]
End```

## 3. C Program to find the largest element in an array

Let us now implement the above execution of the program to find the largest element of the given array in C.

```#include <stdio.h>
int num;
int largestNumber;
int arr;

void checkLargestElement() {
largestNumber = arr;
// here we store the largest number to arr.
for (int i = 1; i < num; ++i) {
if (largestNumber < arr[i]) {
largestNumber = arr[i];
}
}
}

for (int i = 0; i < num; ++i) {
printf("Enter number%d: ", i + 1);
scanf("%d", &arr[i]);
}
}

int main() {
printf("Enter the number of elements in the array: ");
scanf("%d", &num);
checkLargestElement();
printf("The Largest element in the array is = %d", largestNumber);
return 0;
}```
```Output
Enter the number of elements in the array: 4
Enter number1: 65
Enter number2: 48
Enter number3: 71
Enter number4: 95
The Largest element in the array is = 95```

Note: We can simply find the smallest element in the array by reversing the `if` condition check. Please try it and share your solution in the comments.
