Answer 1

Hey there,

Anna and kiRA are correct.

First, you need to get the user's name

getline(cin, name);

Then, you need to compare the name to an empty string.

if (name != "") {
cout << "Welcome, " << name << "!";
}

That's it! You don't need an else statement because it will just be empty.

Coder C++

I would recommend that you use the following if statement:

if (name != "" && name != " " && name != "1" && name != "2" && name != "3" && name != "4" && name != "5" && name != "6" && name != "7" && name != "8" && name != "9" && name != "0") {
cout << "Welcome," << name << "!";
}

I know, it is not the best, but once you are completely familiar to functions, you can put that whole block of code in its own function.

Answer 3

string name{};
cout<<"Register you name: ";
do {
getline(cin,name);
} while(name == "");

Answer 4

use loop and *if-else statement for checking whether string is empty or not*

Answer 5

Edwin Pratt the program can still run whenever a user enters anything though an integer
