Question

Very difficult and confusing assignment for C++ need help!

Write a program that prompts a user to enter a line of text (including whitespace). Please use string object NOT C-string, a string library can be included. 1. Convert the input into uppercase and output the string to the screen. 2. Get the first and the last characters then appends the line with "I Love C++" and output the string to the screen. Example: Input: Hello, How are you? Output 1: HELLO, HOW ARE YOU? Output 2:H? I Love C++ Example: Input: I am the best. Output 1: I AM THE BEST Output 2: AT I Love C++ Example: Input: GOOD LUCK Output 1: GOOD LUCK Output 2: GK I Love C++

CODE:

#include <iostream>
#include <algorithm>
#include <string>

using namespace std;

int main()
{
string s1;
string s2=" I Love C++";
cout << "Enter line fo text " << endl; //prompting user to enter text
getline(cin, s1); //reading line of text
std::transform(s1.begin(), s1.end(), s1.begin(), std::ptr_fun<int, int>(std::toupper)); //converting line fo text to upper case

  

cout << s1<<endl; //printing transformed upper case line fo text
cout<<s1[0]<<s1[s1.length()-1]<<s2<<endl; //printing first and last character of string with "I Love C++"
return 0;
}

SCREENSHOT:

1 #include <iostream> 2 #include <algorithm> 3 #include <string> 4. 5 using namespace std; 6 7 int main() 8{ 9 string si; 10 string s2=" I Love C++"; 11 cout<<"Enter line fo text " << endl; //prompting user to enter text 12 getline(cin, s1); //reading line of text 13 std::transform(s1.begin(), s1.end(), s1.begin(), std::ptr_funsint, int>(std:: toupper)); //converting line fo text to upper case 14 15 16 17 cout << s1<<endl; //printing transformed upper case line fo text 18 cout<<s1[0]<<s1[s1.length()-1]<<s2<<endl; //printing first and last character of string with "I Love C++" 19 return 0; 20 } 21

OUTPUT:

Enter line fo text Hello, How are you? HELLO, HOW ARE YOU? H? I Love C++ ... Program finished with exit code 0 Press ENTER to exit console.

Enter line fo text GOOD LUCK GOOD LUCK GK I Love C++ ... Program finished with exit code o Press ENTER to exit console. I
