Finding the Largest of N Numbers Using C Program

C programming offers a versatile platform for solving various computational problems, including finding the largest of N numbers. This problems involves identifying the maximum value among a given set of numbers.

Understanding the Problem

The primary objective is to write a C program that can determine the largest number among a given set of N numbers. This program should take N numbers as input and output the largest among them.

Approach and Algorithm for Finding Largest of N Numbers

To solve this problem, we can employ a straightforward approach:

1. Initialize Variables: Begin by initializing variables, such as num, which represents the total numbers, and max, which will store the maximum number found so far.
2. Input Numbers: Prompt the user to enter num numbers.
3. Find the Largest Number: Compare each entered number with the current max value. If the entered number is greater than max, update the max value.
4. Output the Result: After iterating through all num numbers, display the max value as the largest number among the given inputs.

C Program to Find Largest of N Numbers

#include <stdio.h>

void main() {
    int num, i;
    float inputNum, max;

    // Prompt user for the total number of elements
    printf("Enter the total number of elements: ");
    scanf("%d", &num);

    // Edge case: If no elements are given
    if (num <= 0) {
        printf("No numbers entered. Exiting...");
    }

    // Initialize max with the first number
    printf("Enter number 1: ");
    scanf("%f", &max);

    // Iterate through the remaining numbers
    for (i = 2; i <= num; i++) {
        printf("Enter number %d: ", i);
        scanf("%f", &inputNum);

        // Compare inputNum with max and update max if inputNum is greater
        if (inputNum > max) {
            max = inputNum;
        }
    }

    // Display the largest number
    printf("The largest number is: %.2f\n", max);
}

Output

In the above c program we are finding largest of n numbers. we can also use same logic with array of n elements to find largest number
