Final answer:
To solve this schoolwork task, you need to read a text input using getline in C++, store it in a string, then find and replace specific abbreviations from the string, ensuring that each is only expanded once before outputting the updated string.
Step-by-step explanation:
The code in question requires you to read a line of input from the user in C++, output it, and then re-output the same line with certain abbreviations expanded to their full forms. Utilizing the getline function will allow you to read an entire line into a string, then use conditional statements to find and replace abbreviations before printing it out.
To ensure each abbreviation is only expanded once, a flag can be used for each abbreviation to indicate whether it has been expanded already. Here is a simple code outline to help you get started:
\#include <iostream>
#include <string>
int main() {
std::string text;
std::cout << "Enter text: ";
std::getline(std::cin, text);
std::cout << "You entered: " << text << '\\';
// Code to search for abbreviations and replace them
// while ensuring each is expanded only once
std::cout << "Expanded: " << expandedText << '\\';
return 0;
}
