C++ Program to Generate multiplication table

In this article, we will discuss the concept of C++ Program to generate multiplication table..

In this program, we are going to learn how to generate a multiplication table using 5 ways in C++ language.

This is done using for loop , while loop , do-while loop , method and recursion

Program to Generate multiplication table – using for loop

In this program, we will display multiplication table of given number using for loop in C++ language

Program 1

#include <iostream>
#include <conio.h>
using namespace std;

int main()
{
    int num;
    cout << "Enter an integer!" << endl;
    cin>>num;
    for(int i=1; i<=10; i++){
        cout<<num<<" * "<<i<<" = "<<num*i << endl;
    }
    getch();
    return 0;
}

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

Enter an  integer

13
13 * 1 = 13
13 * 2 = 26
13 * 3 = 39
13 * 4 = 52
13 * 5 = 65
13 * 6 = 78
13 * 7 = 91
13 * 8 = 104
13 * 9 = 127
13 * 10 = 130

integer variable num and i are declared.
The program asks input from the user
Then the user enters the input values for num.
The program will read the input using cin>> and store to the variable num
Create a for loop of i from 1 to 10 and increase the value of i after every iteration by 1
finally, the program displays the multiplication table using cout<<.

Program to Generate multiplication table – using while loop

In this program, we will display multiplication table of given number using while loop in C++ language

Program 2

#include <iostream>
#include <conio.h>
using namespace std;

int main()
{
    int num;
    cout << "Enter an integer!" << endl;
    cin>>num;
    int i=1;
    while(i<=10){
        cout<<num<<" * "<<i<<" = "<<num*i << endl;
        i++;
    }
    getch();
    return 0;
}

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

Enter an  integer

7
7 * 1 = 7
7 * 2 = 14
7 * 3 = 21
7 * 4 = 28
7 * 5 = 35
7 * 6 = 42
7 * 7 = 49
7 * 8 = 56
7 * 9 = 63
7 * 10 = 70

integer variable num and i are declared.
The program asks input from the user
Then the user enters the input values for num.
The program will read the input using cin>> and store to the variable num
Create a while loop of i from 1 to 10 and increase the value of i after every iteration by 1
finally, the program displays the multiplication table using cout<<.

Program to Generate multiplication table – using Do-while loop

In this program, we will display multiplication table of given number using do-while loop in C++ language

Program 3

#include <iostream>
#include <conio.h>
using namespace std;

int main()
{
    int num;
    cout << "Enter an integer!" << endl;
    cin>>num;
    int i=1;
   do{
        cout<<num<<" * "<<i<<" = "<<num*i << endl;
        i++;
    } while(i<=10);
    getch();
    return 0;
}

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

Enter an  integer

11
11 * 1 = 11
11 * 2 = 22
11 * 3 = 33
11 * 4 = 44
11 * 5 = 55
11 * 6 = 66
11 * 7 = 77
11 * 8 = 88
11 * 9 = 99
11 * 10 =110

integer variable num and i are declared.
The program asks input from the user
Then the user enters the input values for num.
The program will read the input using cin>> and store to the variable num
Create a do-while loop of i from 1 to 10 and increase the value of i after every iteration by 1
finally, the program displays the multiplication table using cout<<.

Program to Generate multiplication table – using function

In this program, we will display multiplication table of given number using function

Program 4

#include <iostream>
#include <conio.h>
using namespace std;

void mulTable(int);//function prototype
int main()
{
    int num;
    cout<<"Enter a positive number\n";
    cin>>num;
    cout<<"\nMutiplication table for "<<num<< "is\n";
    mulTable(num);//function call
    getch();
    return 0;
}
void mulTable(int num)//function definition
{
    int i;
    for(i=1; i<=12; i++ ){
         cout<<num<<" * "<<i<<" = "<<num*i<<"\n";
    }
}

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

Generate multiplication table

Declare a function named as mulTable(int); with parameter
integer variables num is declared.
The program asks input from the user
Then the user enters the input values for num.
The program will read the input using cin>> and store the variable num.
Define the function mulTable(int); to print multiplication table
Call the function to produce output
finally, the program displays the multiplication table using cout<<.

Program to Generate multiplication table – using recursion

In this program, we will display multiplication table of given number using recursive function

Program 5

#include <iostream>
#include <conio.h>
using namespace std;

int mulTable(int,int);//function prototype
int main()
{
    int num,i=1;
    cout<<"Enter a positive number\n";
    cin>>num;
    cout<<"\nMutiplication table for "<<num<< " is\n";
    mulTable(num,i);//function call
    getch();
    return 0;
}
int mulTable(int num,int i)//function definition
{
    if(i>10){
        return 0;
    }
    else
    {
        cout<<num<<" * "<<i<<" = "<<num*i << endl;
        return mulTable(num,i+1);
    }
}

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