Is there a way to reverse a string in C + +?
Given a string, write a C/C++ program to reverse it. Write own reverse function by swapping characters: One simple solution is to write our own reverse function to reverse a string in C++. Using inbuilt “reverse” function: There is a direct function in “algorithm” header file for doing reverse that saves our time when programming.
How to reverse a string of length n?
It is to be noted that for reversing a string of length n, you only need n/2 iterations. Now, once the swapping of strings is done, you need another looping to display the reversed string, which is done using this in our program: So, now the user-defined function body is ready with logic.
How to reverse a string using swapping logic?
Then a user-defined function, revAString () is declared and in its definition, reversing the string using swapping logic is written. First of all, you take g (a counter variable), a variable numb of type integer and a temporary variable (name tmpry) used for swapping and initialize this temporary variable with 0.
