Find the Largest of n Numbers Using the C Program

In the world of programming finding the largest element is a common task. In this article, we are going to write a C program to find the largest of n numbers.

Objective

The objective of this tutorial is to write a C program that accepts n numbers as input and finds the largest among them.

Algorithm for Finding the Largest Number

To write a C program that efficiently finds the largest number among n numbers, We will use a simple algorithm. The steps of the algorithm are given below-

• Start the program.
• Declare Variables – n for a total count of numbers, num to hold each input number, and largest to hold the largest of n numbers.
• Start a loop to take n numbers as input.
• Compare num with largest, if num>largest assign num to largest that is largest = num.
• Display the largest number as the output.
• End of thev program.

C Program for Finding the Largest Number

Let’s implement the above algorithm using the C program.

#include <stdio.h>
void main()
{
    int n, num, largest;
    printf("Enter the total count of number");
    scanf("%d", &n);
    printf("Enter all the numbers one by one\n");
    scanf("%d", &largest);
    for (int i = 2; i <= n; i++)
    {
        scanf("%d", &num);
        if (num > largest)
        {
            largest = num;
        }
    }
    printf("Largest number = %d", largest);
}

Output

The above C program asks the user to input a total number of counts after that proceeds to accept n numbers one by one, using a loop. It compares each input number with the largest and updates the largest if the new number is greater.
