C Program to Find Largest Number in an Array

C program to find the largest number from an array; Through this tutorial, we will learn how to find largest or maximum number in an array using standard method, function and recursion in c programs.

Programs to Find Largest Number in an Array in C

  • C Program to Find Largest Number in an Array using Standard Method
  • C Program to Find Largest Number in an Array using Function
  • C Program to Find Largest Number in an Array using Recursion

C Program to Find Largest Number in an Array using Standard Method

#include <stdio.h>
 
int main()
{
    int a[1000],i,n,max;
   
    printf("Enter size of the array : ");
    scanf("%d",&n);
 
    printf("Enter elements in array : ");
    for(i=0; i<n; i++)
    {
        scanf("%d",&a[i]);
    }
 
    max=a[0];
    for(i=1; i<n; i++)
    {
		   if(max<a[i])
		    max=a[i];       
    }
          printf("\nmaximum of array is : %d",max);
 
 
    return 0;
}

The output of the above c program; as follows:

Enter size of the array : 5
Enter elements in array :  9 8 7 6 5
9 8 7 6 5

maximum of array is : 9

C Program to Find Largest Number in an Array using Function

#include <stdio.h>
 
 int sumofarray(int a[],int n)
 {
 	int max,i;
 	max=a[0];
    for(i=1; i<n; i++)
    {
		   if(max<a[i])
		    max=a[i];       
    }
    
    printf("\nmaximum of array is : %d",max);
 }
int main()
{
    int a[1000],i,n,sum;
   
    printf("Enter size of the array : ");
    scanf("%d", &n);
 
    printf("Enter elements in array : ");
    for(i=0; i<n; i++)
    {
        scanf("%d",&a[i]);
    }
    sumofarray(a,n);
 
 
    
}

The output of the above c program; as follows:

Enter size of the array : 5
Enter elements in array : 1 9 2 8 7
maximum of array is : 9

C Program to Find Largest Number in an Array using Recursion

#include<stdio.h>

#define MAX 100

int getMaxElement(int []);  // takes array of int as parameter
int size;

int main()
{
    int arr[MAX], max, i;
    printf("\n\nEnter the size of the array: ");
    scanf("%d", &size);
    printf("\n\nEnter %d elements\n\n", size);

    for(i = 0; i < size; i++)
    {
        scanf("%d", &arr[i]);
    }
    
    max = getMaxElement(arr);   // passing the complete array as parameter
    printf("\n\nLargest element of the array is %d\n\n", max);

    return 0;
}

int getMaxElement(int a[])
{
    static int i = 0, max =- 9999;  // static int max=a[0] is invalid
    if(i < size)   // till the last element
    {
        if(max < a[i])
        max = a[i];

        i++;    // to check the next element in the next iteration
        getMaxElement(a);   // recursive call
    }
    return max;
}

The output of the above c program; as follows:

Enter the size of the array: 5
Enter 5 elements

5 99 45 65 2
Largest element of the array is 99
