Write some \(\mathrm{C}++\) code that will read a line of text and echo the line with all uppercase letters deleted.

Short Answer

Expert verified

Question: Write a C++ program that reads a line of text and outputs the same line with all uppercase letters removed. Answer: You can create a C++ program that follows these steps: 1. Include the necessary headers and namespace. 2. Create a main function. 3. Read a line of text from the user. 4. Iterate through the characters and remove uppercase letters. 5. Display the modified string. Here's the complete code: ```cpp #include #include using namespace std; int main() { string text; cout << "Enter a line of text: "; getline(cin, text); string output; for(char letter : text) { if(!isupper(letter)) { output += letter; } } cout << "Output: " << output << endl; return 0; } ``` This program reads a line of text from the user, iterates through each character to remove uppercase letters, and then displays the modified string.

Step by step solution

Include the necessary headers and namespace

Firstly, we need to include "iostream" and "string" header files and the standard namespace std, as we will be using the cin, cout and getline functionalities: ```cpp #include #include using namespace std; ```

Create a main function

Next, we'll write the main function where we'll prompt the user for input and process the given text: ```cpp int main() { // Your code will be placed here } ```

Read a line of text from the user

Inside the main function, declare a string variable called "text" and use the getline() function to read a line of text from the user: ```cpp string text; cout << "Enter a line of text: "; getline(cin, text); ```

Iterate through the characters and remove uppercase letters

Now, we will iterate through each character in the given text and check if it is an uppercase letter. If it is not, we will add it to a new string called "output": ```cpp string output; for(char letter : text) { if(!isupper(letter)) { output += letter; } } ```

Display the modified string

Finally, we will display the resulting string without uppercase letters to the user: ```cpp cout << "Output: " << output << endl; ``` Now, let's combine all the steps into a complete C++ program: ```cpp #include #include using namespace std; int main() { string text; cout << "Enter a line of text: "; getline(cin, text); string output; for(char letter : text) { if(!isupper(letter)) { output += letter; } } cout << "Output: " << output << endl; return 0; } ``` This program will successfully read a line of text and output the line with all uppercase letters removed.
