Find Largest or Biggest Number In Array Program

/*##Find Largest or Biggest Number In C++*/
/*##Calculation Programs In C++, Array Example Programs In C++*/

// Header Files
#include <iostream>
#include<conio.h>

using namespace std;

#define ARRAY_SIZE 5

int main()
{
    int numbers[ARRAY_SIZE], i, largest;

	cout<<"Find Largest or Biggest Number (Array) In C++ Example Program\n";

    for (i = 0; i < ARRAY_SIZE; i++)
    {
		cout<<"Enter the Number : "<< (i+1) <<"  : ";
        cin>>numbers[i];
    }

    largest = numbers[0];
    for (i = 1; i < ARRAY_SIZE; i++)
    {
        if (largest < numbers[i])
            largest = numbers[i];
    }
    cout<<"\nLargest /Biggest Number Is : "<<largest;
    
    getch();
    return 0;
}

Sample Output

Enter the Number : 1  : 34
Enter the Number : 2  : 54
Enter the Number : 3  : 78
Enter the Number : 4  : 12
Enter the Number : 5  : 56

Largest /Biggest Number Is : 78

How It Works

This C++ program demonstrates Find Largest or Biggest Number in Array. It first reads the required values as input, then walks through the data with a loop to compute the result, and finally prints the output shown in the Sample Output above.

1. Declare the variables that hold the program’s data.
2. Read the input values that the program will work with.
3. Iterate over the data using a loop to apply the logic.
4. Use conditional statements to handle the different cases.
5. Print the final result to the console so you can compare it with the sample output.

Try changing the input values and re-running the program to see how the output changes — this is the fastest way to understand how the logic behaves.
