# Largest number in array using Recursion

Write a C Program to find largest number in array using Recursion. Here’s simple Program to find largest number in  array using Recursion in C Programming Language.

## Recursion : :

• Recursion is the process of repeating items in a self-similar way. In programming languages, if a program allows you to call a function inside the same function, then it is called a recursive call of the function.
• The C programming language supports recursion, i.e., a function to call itself. But while using recursion, programmers need to be careful to define an exit condition from the function, otherwise it will go into an infinite loop.
• Recursive functions are very useful to solve many mathematical problems, such as calculating the factorial of a number, generating Fibonacci series, etc.

## Problem : :

This C Program prints the largest number in an unsorted array of elements using recursion. The array used here is of type integer.

Here is the source code of the C Program to find largest number in array using Recursion. The C Program is successfully compiled and run on a Linux system. The program output is also shown below.

### SOURCE CODE : :

```/*  C Program to find largest number in array using Recursion  */

#include <stdio.h>

int large(int[], int, int);

int main()
{
int size;
int largest;
int list[20];
int i;

printf("Enter size of the list :: ");
scanf("%d", &size);
printf("\nPrinting the list :: \n\n");
for (i = 0; i < size ; i++)
{
list[i] = rand() % size;
printf("\t%d", list[i]);
}
if (size == 0)
{
printf("\nEmpty list\n");
}
else
{
largest = list[0];
largest = large(list, size - 1, largest);
printf("\n\nThe largest number in the list is :: %d \n", largest);
}

return 0;
}
int large(int list[], int size, int largest)
{
if (size == 1)
return largest;

if (size > -1)
{
if (list[size] > largest)
{
largest = list[size];
}
return(largest = large(list, size - 1, largest));
}
else
{
return largest;
}
}```

### Output : :

```/*  C Program to find largest number in an array using Recursion  */

Enter size of the list :: 10

Printing the list ::

1       7       4       0       9       4       8       8       2       4

The largest number in the list is :: 9

Process returned 0```

Above is the source code for C Program to find largest number in array using Recursion which is successfully compiled and run on Windows System.The Output of the program is shown above .
