In this C++ tutorial, you will learn how to use Arithmetic Multiplication Operator with values of different datatypes using example programs.

C++ Multiplication

In C++, Multiplication is performed using arithmetic operator *. The operator takes two operands and returns the product of two operands.

1. Multiplication of Integers

You can multiply two integers using multiplication operator. The datatype of the operands and returned value is given in the following code snippet.

int = int * int

In the following program, we initialize two integer variables and multiply them using multiplication operator.

C++ Program

#include <iostream>  
using namespace std;

int main() {
   int a = 12;
   int b = 7;

   int product = a * b;

   cout << product << endl;
}

Output

84

2. Multiplication of Floating Point Numbers

You can multiply two floating point numbers using multiplication operator. The datatype of the operands and returned value is given in the following code snippet.

float = float * float

In the following program, we initialize two floating point variables and multiply them using multiplication operator.

C++ Program

#include <iostream>  
using namespace std;

int main() {
   float a = 1.2;
   float b = 0.6;

   float product = a * b;

   cout << product << endl;
}

Output

0.72

3. Multiplication of Integer and Floating Point Number

You can multiply an integer and floating point number using multiplication operator. The datatype of the operands and returned value is given in the following code snippet.

float = int * float

In the following program, we initialize an integer variable and a floating point variable and multiply them using multiplication operator.

C++ Program

#include <iostream>  
using namespace std;

int main() {
   int a = 2;
   float b = 1.3;

   float product = a * b;

   cout << product << endl;
}

Output

2.6

4. Multiplication of Chars

You can multiply two characters using multiplication operator. The datatype of the operands and returned value is given in the following code snippet.

char = char * char

In the following program, we initialize two character variables and multiply them using multiplication operator.

C++ Program

#include <iostream>  
using namespace std;

int main() {
   char ch1 = 9;
   char ch2 = 8;

   char ch = ch1 * ch2;

   cout << ch << endl;
}

Output

H

5. Multiplication of Boolean values

You can multiply two boolean values using multiplication operator. The operator converts false to 0, true to 1 and then performs multiplication operation. The datatype of the operands and returned value is given in the following code snippet.

bool = bool * bool

Arithmetic Multiplication on two boolean values is equivalent to logical AND operation.

In the following program, we initialize two boolean variables and multiply them using multiplication operator.

C++ Program

#include <iostream>  
using namespace std;

int main() {
   bool a = true;
   bool b = false;

   bool c = a * b;

   cout << c << endl;
}

Output

0

Chaining of Multiplication Operator

You can chain Multiplication Operator and perform the multiplication of more than two operands in a single statement. The psudo code is given below.

result = operand_1 * operand_2 * operand_3 * ... * operand_n

In the following example, we shall take four integer variables and multiply them altogether in a single statement using arithmetic multiplication operator.

C++ Program

#include <iostream>  
using namespace std;

int main() {
   int a = 12;
   int b = 25;
   int c = 61;
   int d = 37;

   int product = a * b * c * d;

   cout << product << endl;
}

Output

677100
