Logic to find length of a string

  1. Input a string from user. Store it in some variable say text.
  2. Initialize a counter variable to zero, say count = 0.
  3. To iterate through input string, run a loop from 0 to the last character of string i.e. NULL character.
  4. Inside the loop increment the counter variable with 1 i.e. count++.

How do you find the length of a string without using strlen in C++?
