Answer 1

You should use the getline() function, not the simple cin, for cin only gets the string before white space.

istream& getline ( istream& is, string& str, char delim ); 

istream& getline ( istream& is, string& str );

Extracts characters from is and stores them into str until a delimiter character is found.

The delimiter character is delim for the first function version, and '\n' (newline character) for the second. The extraction also stops if the end of file is reached in is or if some other error occurs during the input operation.

If the delimiter is found, it is extracted and discarded, i.e. it is not stored and the next input operation will begin after it.

Answer 2

you can use getline so like this

string abc;
cout<<"Enter Name";
getline(cin,abc);
cout<<abc;

Getline

Answer 3

Another alternative is to use the std::strings getline() function like this

getline(cin, studname);

This will get the whole line and strip of the newline. But any leading/trailing spaces will be in your string.

Answer 4

cin likes to break things up by whitespace, so that is why you are only getting one name. Likely, since the assignment is telling you to grab the first and last name, you can likely assume that these will be separated by whitespace. In this case, you can just grab both separately, then concatenate them:

string firstname = "default";
string lastname = "default";

cin >> firstname >> lastname;

return firstname + " " + lastname;

Answer 5

To get an entire line, you'll want to use getline instead of >>:

getline(cin, myString);
