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.

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
```

Flowchart:

C Programming Code Editor:

```#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;
}```
