Hello, and welcome! Are you ready to elevate your string manipulation skills in C++? Today, we'll delve into a task that bolsters your comprehension of strings and enhances your creativity. The task involves splitting a string into words and then reversing each word as if reflected in a mirror. Does that sound interesting? Let's get started!

You're tasked with considering a string filled with words and writing a C++ function that accepts this string. The function should reverse the character order of each word and form a new string consisting of these reversed words.

Here's what you need to keep in mind:

• The input string will contain between 1 and 100 words.
• Each word in the string is a sequence of characters separated by white space.
• The characters can range from a to z, A to Z, 0 to 9, or even an underscore _.
• The provided string will neither start nor end with a space, and double spaces won't be present either.
• After reversing the words, your program should output a single string with the reversed words preserving their original order.

Example

Consider the input string "Hello neat cpp_lovers_123".

The function works as follows:

• 'Hello' becomes 'olleH'
• 'neat' becomes 'taen'
• 'cpp_lovers_123' becomes '321_srevol_ppc'

Afterward, it forms a single string with these reversed words, producing "olleH taen 321_srevol_ppc".

Therefore, if you call reverseWords("Hello neat cpp_lovers_123"), the function should return "olleH taen 321_srevol_ppc".

Let's begin breaking this down!

Our first task is to separate the words in the sentence. Unlike Python, C++ does not provide a built-in split() function. However, we can employ the string stream available in C++. A stringstream keeps a string internally, allowing us to extract words from the string. Here is a sample code to illustrate this:

Next, we need to reverse each word separated in the previous step. In C++, the std::reverse() function, found in the <algorithm> library, allows us to do this. Let's add these lines to our existing code:

Finally, we need to consolidate these reversed words into a single string, separated by spaces. We can achieve this using an ostringstream from the C++ Standard Library. Here's how we do that:

First, we push the first word to the stream, then push a space followed by the next word in a loop. This way, we add all words while preserving the format. To get the resulting string, we can call oss.str().

It remains for us to combine the code from the steps together in a function reverseWords and call it from main to test.

Well done! By completing this lesson, you've sharpened your proficiency in manipulating strings in C++. You've especially improved in reversing the order of characters in a word. I hope you're feeling confident and excited about your C++ skills. Remember, mastering these skills requires frequent practice. Therefore, take some time to explore related problems and practice what you’ve learned. Enjoy the journey of learning!
