This C++ program multiplies two given numbers without using multiplication operator. The multiplication is achieved by use of a for loop which keeps adding first number to variable product in each iteration till the value of second number drops to 0.
Here is the source code of the C++ program multiplies two given numbers without using multiplication operator. The C++ program is successfully compiled and run on a Linux system. The program output is also shown below.
* C++ Program to multiply numbers without * operator
long op1, op2, product = 0;
std::cout << "Enter the numbers ";
std::cin >> op1 >> op2;
while(op2 > 0)
product = product + op1;
std::cout << std::endl << "The product of " << op1
<< " and " << op2 << " is " << product;
Enter the numbers 10 20
The product of 10 and 20 is 200
