Program 28 - CSU1128 - CSE 2026 - Shoolini University

Program to find the maximum number from the numbers stored in an array entered by the user

Explanation

The program finds and prints the maximum number from a list of numbers entered by the user.

Header

The code begins with including the standard input-output header file using #include <stdio.h>.

Variable Declaration

The main() function is defined, and three integer variables d, m, and o are declared:

int d: Stores the total number of numbers entered by the user.
int m: Used as a loop counter.
int o: Stores the maximum number found in the array.

Program Description

The program prints a description message for the user to understand its functionality.

User Input

The user is prompted to enter the total number of numbers they want to find the maximum from. The input is read using scanf("%d", &d);.

Array Input and Initialization

The program dynamically creates an array to store the numbers entered by the user:

int j[d];: Declares an array j of size d to store the numbers.
for (m = 0; m < d; m++): Loops through each position in the array.
printf("\tNumber %d: ", m + 1);: Prompts the user to enter a number.
scanf("%d", &j[m]);: Reads the entered number and stores it in the array.

Finding the Maximum Number

The program finds the maximum number in the array:

o = j[0];: Initializes o to the first element of the array.
for (m = 0; m < d; m++): Loops through each position in the array.
if (j[m] > o): Checks if the current element is greater than the current maximum.
o = j[m];: Updates the maximum number if the condition is true.

Output Result

The program prints the maximum number found in the array.

Program End

The program ends with printf("\n\n"); to print a new line and return 0; to indicate successful execution.

Output

Program to find the maximum number from the numbers stored in an array entered by the user. Example 3 8 5 = 8

Enter total number of numbers you want to find the maximum number from - (Example: 5) - and press enter: 5
Number 1: 45
Number 2: 76
Number 3: 56
Number 4: 87
Number 5: 67
The maximum number from the entered array of numbers is 87
