Dividing two numbers

You are given two numbers A and B, You have to divide A by B without using division operator and modulus operator ? PS: Repeated Subtraction is not allowed.. I have thought of a solution but i am not satisfied with that so asking for help of CEans

hi!! dude the following code serves your purpose!!
#include<stdio.h>
void main()
{
float a,b,r=0;
printf("\n\n\tEnter Values of a & b :");
scanf("%d%d",&a,&b);
while(b*r <= a)
r++;
printf("\n\n\tAnswer is : %d ",r-1);
}

Have a Nice time!!(Note : It's for Integers!! ie, i've not taken floating point division to easy the task!!)

Are you sure? This action cannot be undone.

Thats OK...Actually its a YAHOO interview question.
I thought of doing like this :-
We have to calculate y=A/B
So take log of both sides
log y=log(A/B)
log y=log A - log B
calculate log A - log B=x say
Then take antilog both sides
y=antilog (x)

In this way we can find A/b without using / and % operator.
Thats what i thought

Here, I think the printf statement should be outside the while loop!! 😀

no!! it's not inside d while loop!! it's outside itself try it out by Executing!!

it's d simplest one & it takes very less cpu cycle time compared to ur other method!! & mor over logic is simple!
