Write a method named toBinary that accepts an integer as a parameter and returns a string of that number's representation in binary. For example, the call of toBinary (42) should return "101010".

using c++

#include

string toBinary (int number) {

int reminder;

string result;

while (number==0) {

remainder=number%2;

number=number/2;

result=result + (char) remainder;

}

result=strrev (result);

return result;

}

Explanation:

the function toBinary () takes number as parameter and return binary value of that number in string format. we are iterating while loop until the number becomes 0.% operator gives remainder and / operator gives quotient. we are storing all remainders by dividing the number with 2 and making quotient as number in each iteration. at the end we are reversing the remainders to get binary equivalent of the number and returning that.
