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

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

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;
}

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

multiplication table

int main() {
    const int size=10;
    // Size of the multiplication table (1 to 10)
    int table[size][size];

    //using nested do-while loop
    int i=0; 
    do{

       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++;
