C Program to Find Maximum and Minimum from 10 Numbers

Introduction:

Finding the maximum and minimum number from a set of values is one of the most common beginner-level programming problems. This tutorial explains how to write a C program to find maximum and minimum from 10 numbers using loops and conditional checks.

This is an essential concept that helps build skills in loops, conditionals, arrays, and logic.

---

Problem Statement:

Write a C program that:

• Takes 10 numbers as input from the user.
• Identifies and displays the maximum and minimum values from the entered numbers.

---

C Program Code:

#include <stdio.h>

int main() {
    int numbers[10], i;
    int max, min;

    // Input 10 numbers from user
    printf("Enter 10 numbers:\n");
    for (i = 0; i < 10; i++) {
        scanf("%d", &numbers[i]);
    }

    // Initialize max and min with first number
    max = min = numbers[0];

    // Compare each number with current max and min
    for (i = 1; i < 10; i++) {
        if (numbers[i] > max) {
            max = numbers[i];
        }
        if (numbers[i] < min) {
            min = numbers[i];
        }
    }

    // Display results
    printf("Maximum number is: %d\n", max);
    printf("Minimum number is: %d\n", min);

    return 0;
}

---

Explanation of the Code:

• An array of size 10 is used to store user input.
• We initialize both max and min with the first number.
• The program then loops through the rest of the array, updating max and min as it finds higher or lower values.
• Finally, it prints the maximum and minimum values.

---

Why It Matters:

• Teaches basic looping and array traversal
• Enhances understanding of comparative logic
• Common use case in real-world data analysis or search operations

---

Where This Logic Is Used:

• Stock price analysis
• Performance tracking systems
• Exam result evaluation
• Any form of range or threshold calculations

• Difference Between Arrays and Loops in C

Conclusion:

This program demonstrates a fundamental use case in C programming — finding maximum and minimum values from a set of inputs. It’s simple, efficient, and a great way to practice loops, conditionals, and array handling.
