How do binary strings work in C++?

Program to add two binary strings in C++

  1. Input str1 = {“11”}, str2 = {“1”}
  2. Output “100”
  3. Input str1 = {“110”}, str2 = {“1”}
  4. Output “111” Approach used below is as follows to solve the problem. Traverse both the string from last. Add the binary of two numbers. If there are two 1’s then make it zero and carry 1.
