In C++ 5.17 LAB: AcronymsAn acronym is a word formed from the initial letters of words in a set phrase. Write a program whose input is a 4-word phrase and whose output is an acronym of the input. If a word begins with a lowercase letter, don't include that letter in the acronym. Assume there will be at least one uppercase letter in the input.Example: If the input is: Association for Computing Machinerythe output should be: ACMYour program must define and call a function that returns the acronym created for the given userPhrase.```cppstring CreateAcronym(string word1, string word2, string word3, string word4)```Hints:1. Use `isupper()` to check if a letter is uppercase. `isupper(ch)` returns true if `ch` is a char variable containing an uppercase letter ('A'..'Z'), otherwise it returns false. You can use it in the if condition.2. Use `str.append(1, ch)` to append a character in char variable `ch` to the end of the string `str`. The `1` tells the function to append exactly 1 character.3. Do **not** use `getline`.---### Lab Activity: Code Template```cpp#include using namespace std;/* Define your function here */```(Note: The code segment above serves as a template for writing your program. Replace comments with actual code.) ### Educational Content on C++ Programming: Creating Acronyms#### Hints for the Lab Activity:1. **Hint 2**: Use `str.append(1, ch)` to append a character in the char variable `ch` to the end of the string `str`. The `1` specifies that the function should append exactly one character.2. **Hint 3**: Avoid using `getline`.---#### Lab Activity: 5.17.1 LAB: AcronymsThis section involves writing a C++ program to create acronyms using given words. Below is the skeleton code you will be working with:```cpp#include using namespace std;/* Define your function here */int main() { string word1; string word2; string word3; string word4; /* Type your code here */ return 0;}```- **Lines 1-2**: The `#include ` directive includes the Input/Output stream library for standard I/O operations. The `using namespace std;` line allows you to use elements from the standard library without prefixing `std::`.- **Lines 5-13**: This is where you will define your main function and begin writing your code to generate acronyms from strings entered by the user.#### Developing and Submitting Code:- **Develop Mode**: Allows you to write and test your code. You can run the program as many times as needed to ensure accuracy before submitting.- **Enter Program Input (Optional)**: If your code requires input values, you can specify them here.- **Run and Submit**: After entering any necessary inputs, click on "Run program" to observe the output. When satisfied, switch to "Submit mode" for grading.---This activity is designed to enhance your understanding of string manipulation in C++ by using functions like `str.append()`. It provides a practical way to reinforce your learning through hands-on experience.

Dear student, the answer is provided below.

An acronym is a word formed from the initial letters of words in a set phrase. Write a program whose input is a 4 word phrase and whose output is an acronym of the input. If a word begins with a lower case letter, don't include that letter in the acronym. Assume there will be at least one upper case letter in the input. Ex: If the input is: Association for Computing Machinery the output should is: ACM Your program must define and call a function thats returns the acronym created for the given userPhrase. string CreateAcronym (string wordl, string word2, string word3, string word4) Hint 1: Use isupper() to check if a letter is upper case. isUpper(ch) returns true if ch is a char variable containing an uppercase letter (A"..Z'), otherwise it returns false. You can use it in the if condition. Hint 2: Use str.append(1, ch) to append a character in char variable ch to the end of the string str. The 1 tells the function to append exactly 1 character. Hint 3: Do not use getline.
