As your question is stated, the values are supposed to be taken from user. If the input variables are x and y, then just keep adding x with 0 y times!

Well suppose you need to calculate 3*4
keep adding 3 with 0 four times
0+3+3+3+3
use loop to solve this problem

Should the 2 values be integers?

you have to get those put those valuse in a loop,then in every loop decrease one of the valuse one number and sum another one with itself until the first one reach to 0like this:
cin>>n
cin>>m
for(int m,m>0,m--;)
{n=n+n}
