Hi Guys, Welcome to Proto Coders Point, Here is a dart program to **find product of 2 numbers** without using ***** operator.

## Dart program find multiplication of 2 number without * operator

In this dart program, we will not use multiplication operator i.e. *, Instead we will use iteration/loop technique to find the product of 2 number in dart program without * operator.

## Product of 2 number program in dart language – Source Code

void main(){ int a = 2, b = 3, result; result =product(a, b); print('$result'); } // calculate multiplication and return the result int product(int a,int b){ int temp =0; while(b != 0){ temp += a; b--; } return temp; }

**output**

## Program Explanation

In the above dart program,

We habe initialize number to 2 variables **a & b**, & then passing **a,b **values to a functon **‘product()’**, that will perform multiplication **without * operator**.

In **product()** function, we have declared a **temp variable as ‘0’**.

The while loop, check if **‘b’ variable is not equal to ‘0’**, if the while condition is true then execute the iteration loop.

So, inside while loop, we are adding the value of **‘temp’ + ‘a’** variable & then decrement value **‘b’ by -1**.

There when **b == 0**, i.e. b !=0 (condition become false)exit the loop, & therefore we have product of** a * b in temp variable**, which is returned by product function & this we are print multiplication of 2 numbers on console without using dart arithmetic operator.
