C Exercises: Get the largest element of an array
C Recursion: Exercise-8 with Solution
Write a program in C to get the largest element of an array using recursion.
Pictorial Presentation:
Sample Solution:
C Code:
#include<stdio.h>
#define MAX 100
int MaxElem(int []);
int n;
int main()
{
int arr1[MAX],hstno,i;
printf("\n\n Recursion : Get the largest element of an array :\n");
printf("------------------------------------------------------\n");
printf(" Input the number of elements to be stored in the array :");
scanf("%d",&n);
printf(" Input %d elements in the array :\n",n);
for(i=0;i<n;i++)
{
printf(" element - %d : ",i);
scanf("%d",&arr1[i]);
}
hstno=MaxElem(arr1);//call the function MaxElem to return the largest element
printf(" Largest element of the array is: %d\n\n",hstno);
return 0;
}
int MaxElem(int arr1[])
{
static int i=0,hstno =-9999;
if(i < n)
{
if(hstno<arr1[i])
hstno=arr1[i];
i++;
MaxElem(arr1);//calling the function MaxElem itself to compare with further element
}
return hstno;
}
Sample Output:
Recursion : Get the largest element of an array : ------------------------------------------------------ Input the number of elements to be stored in the array :5 Input 5 elements in the array : element - 0 : 5 element - 1 : 10 element - 2 : 15 element - 3 : 20 element - 4 : 25 Largest element of the array is: 25

C Programming: Tips of the Day
Static variable inside of a function in C
The scope of variable is where the variable name can be seen. Here, x is visible only inside function foo().
The lifetime of a variable is the period over which it exists. If x were defined without the keyword static, the lifetime would be from the entry into foo() to the return from foo(); so it would be re-initialized to 5 on every call.
The keyword static acts to extend the lifetime of a variable to the lifetime of the programme; e.g. initialization occurs once and once only and then the variable retains its value - whatever it has come to be - over all future calls to foo().
