# C Exercises: Get largest element of an array

## C Function : Exercise-8 with Solution

Write a program in C to get largest element of an array using the function.
Test Data :
Input the number of elements to be stored in the array :5
Input 5 elements in the array :
element - 0 : 1
element - 1 : 2
element - 2 : 3
element - 3 : 4
element - 4 : 5
Expected Output :

```The largest element in the array is : 5
```

C Code:

```#include<stdio.h>
#define MAX 100

int findMaxElem(int []);
int n;

int main()
{
int arr1[MAX],mxelem,i;
printf("\n\n Function : get 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]);
}
mxelem=findMaxElem(arr1);

printf(" The largest element in the array is : %d\n\n",mxelem);
return 0;
}
int findMaxElem(int arr1[])
{
int i=1,mxelem;
mxelem=arr1[0];
while(i < n)
{
if(mxelem<arr1[i])
mxelem=arr1[i];
i++;
}
return mxelem;
}
```

C Practice online:

```#include<stdio.h>
#define MAX 100

int findMaxElem(int []);
int n;

int main()
{
int arr1[MAX],mxelem,i;
printf("\n\n Function : get 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]);
}
mxelem=findMaxElem(arr1);

printf(" The largest element in the array is : %d\n\n",mxelem);
return 0;
}
int findMaxElem(int arr1[])
{
int i=1,mxelem;
mxelem=arr1[0];
while(i < n)
{
if(mxelem<arr1[i])
mxelem=arr1[i];
i++;
}
return mxelem;
}
```
