- 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
of the function.**recursive call**

- 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.

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 : :**

**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 .
