How to print multiplication table using Array in C++ language

In this post, we will discuss how to print multiplication tables using Array in C++.

In this tutorial, we will discuss how to implement and print a multiplication table in C++ Program to using 2D Array.

Here’s a C++ program to print a multiplication table using nested for loop

How to print multiplication table using Array

Using nested for loop

Program 1

// C++ program to rpint multiplication table using array
#include <iostream>

int main() {
    const int size=10;
    // Size of the multiplication table (1 to 10)
    int table[size][size];
    //Declaring Array to store the multiplication table
    
    //initialize the array with multiplication value
    for(int i=0; i<size; i++){
        for(int j=0; j<size; j++){
        table[i][j]=(i+1)*(j+1);
    }
    }
    //print the multiplication table
    std::cout  << "multiplication table"<<"\n";
    for(int i=0; i<size; i++){
        for(int j=0; j<size; j++){
        std::cout <<table[i][j]<<"\t";
        }
       std::cout<<"\n";
    }

    return 0;
}

When the above code is executed, it produces the following result

multiplication table
1 2 3 4 5 6 7 8 9 10
2 4 6 8 10 12 14 16 18 20
3 6 9 12 15 18 21 24 27 30
4 8 12 16 20 24 28 32 36 40
5 10 15 20 25 30 35 40 45 50
6 12 18 24 30 36 42 48 54 60
7 14 21 28 35 42 49 56 63 70
8 16 24 32 40 48 56 64 72 80
9 18 27 36 45 54 63 72 81 90
10 20 30 40 50 60 70 80 90 100

Array declaration: We declare a 2D array table[size][size] to store multiplication table

Nested for loop : we are used two nested for loop to fill the array with values by multiplying the row and Column indices

Printing the multiplication table: After initialize the array , the table is printed using another set of nested for loop

Here’s a C++ program to print a multiplication table using nested while loop

Program 2

// C++ program to rpint multiplication table using array
#include <iostream>

int main() {
    const int size=10;
    // Size of the multiplication table (1 to 10)
    int table[size][size];
    //Declaring Array to store the multiplication table
    
    //initialize the array with multiplication value
    //using nested while loop
    int i=0; 
    while(i<size){
        int j=0;
        while(j<size){
        table[i][j]=(i+1)*(j+1);
         j++;
    }
     i++;
    }
    //print the multiplication table
    std::cout  << "multiplication table"<<"\n";
    int k=0;
    while(k<size){
        int l=0; 
        while(l<size){
        std::cout <<table[k][l]<<"\t";
         l++;
        }
       std::cout<<"\n";
        k++;
    }

    return 0;
}

Nested while loop : we are used two nested while loop to fill the array with values by multiplying the row and Column indices

Printing the multiplication table: After initialize the array , the table is printed using another set of nested while loop

Here’s a C++ program to print a multiplication table using nested do-while loop

Program 3

// C++ program to rpint multiplication table using array
#include <iostream>

int main() {
    const int size=10;
    // Size of the multiplication table (1 to 10)
    int table[size][size];
    //Declaring Array to store the multiplication table
    
    //initialize the array with multiplication value
    //using nested do-while loop
    int i=0; 
    do{
        int j=0;
       do{
        table[i][j]=(i+1)*(j+1);
         j++;
    } while(j<size);
     i++;
    }while(i<size);
    //print the multiplication table
    std::cout  << "multiplication table"<<"\n";
    int k=0;
    do{
        int l=0; 
        do{
        std::cout <<table[k][l]<<"\t";
         l++;
        }while(l<size);
       std::cout<<"\n";
        k++;
    }while(k<size);

    return 0;
}
