Question

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".

Answer 1

using c++

#include<string.h>

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;

}

Step-by-step 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.
