Mastering C++ String Manipulation: A Step-by-Step Guide
Are you ready to unlock the full potential of C++ strings? Look no further! In this article, we’ll dive into two essential examples that will take your string manipulation skills to the next level.
Example 1: Removing Non-Alphabetic Characters from a C++ String Object
Imagine having a string object filled with unwanted characters, and you need to extract only the alphabets. Sounds like a challenge? Fear not! With this example, you’ll learn how to remove all non-alphabetic characters from a string object.
The program prompts the user to input a string, and then it uses a for loop to iterate through each character. If the character is an alphabet, it’s kept; otherwise, it’s removed. The result is a string containing only alphabets.
Output:
Enter a string: Hello, World!
Output: HelloWorld
Example 2: Removing Non-Alphabetic Characters from a C-Style String
But what if you’re working with a C-style string instead of a string object? No worries! This example shows you how to remove non-alphabetic characters from a C-style string.
The program follows a similar approach, using a for loop to iterate through each character. However, this time, it uses the isalpha() function to check if the character is an alphabet. If it’s not, it’s removed from the string.
Output:
Enter a string: Hello, World!
Output: HelloWorld
