## Q. Write a program to find largest element in an array.

Solution :- In this program, we will find the largest/Maximum value element in an array.

For Example :-
input : arr[]={ 8, 9, 1, 2, 4 }
output : 9

So as we can see that the largest element in arr[] = {8, 9, 1, 2, 4 } is 9 so the output is 9.

#### Largest Number Algorithm

```START
Step 1 → Take an array Arr and define its values
Step 2 → Declare one variable (VAR) and assign 1st element of array to it
Step 3 → Loop for each value of Arr Repeat Step 4
Step 4 → If Arr[I] > VAR, Assign Arr[I] to VAR
Step 5 → After loop finishes, Display VAR which holds the largest element of array
STOP
```

#### Largest Number Program

• C
• C++
• Java
• Python
• C#
• PHP
• ```#include <stdio.h>
int main() {
int i, arr={ 7, 9, 1, -15, 0};
int VAR = arr;
for (i = 1; i < 5; ++i) {
if (VAR < arr[i])
VAR = arr[i];
}
printf("Largest element in an Array is = %d", VAR);
return 0;
}
```
```#include <iostream>
using namespace std;
int main()
{
int i, arr={ 7, 9, 1, -15, 0};
int VAR = arr;
for(i = 1;i < 5; ++i)
{
if(VAR < arr[i])
VAR = arr[i];
}
cout << "Largest element in an Array is = " << VAR;
return 0;
}
```
```public class LFC {
public static void main(String[] args) {
int[] numArray = { 7, 9, 1, -15, 0};
int largest = numArray;
for (int num: numArray) {
if(largest < num)
largest = num;
}
System.out.format("Largest element in an Array is = %d", largest);
}
}
```
```number = [7, 9, 1, -15, 0]
largest_number = max(number);
print("Largest element in an Array is = ", largest_number)
```
```using System;
class LFC
{
static void Main()
{
int i       = 0;
int large   = 0;
//array declaration
int[] arr = {7, 9, 1, -15, 0};
//assigning first element to the array
large = arr;
//loop to compare value of large with other elements
for (i = 1; i < 5; i++)
{
//if large is smaller than other element
//assig that element to the large
if (large < arr[i])
large = arr[i];
}
//finally, we will have largest element, printing here
Console.WriteLine("Largest element in an Array = " + large);
}
}
```
```// Returns maximum in array
function getMax(\$arr)
{
\$n = count(\$arr);
\$max = \$arr;
for (\$i = 1; \$i < \$n; \$i++)
if (\$max < \$arr[\$i])
\$max = \$arr[\$i];
return \$max;
}
// Driver code
\$arr = array(7, 9, 1, -15, 0);
echo "Largest element in an Array : ";
echo(getMax(\$arr));
```
```#include <stdio.h>
int main() {
int i, arr={ 7, 9, 1, -15, 0};
int VAR = arr;
for (i = 1; i < 5; ++i) {
if (VAR < arr[i])
VAR = arr[i];
}
printf("Largest element in an Array is = %d", VAR);
return 0;
}
```

#### Output

```Largest element in an Array is = 9
```
