In my program which is for storing notes, I use std::getline twice to ask the user first for the title of the note, then to ask for the note's body. When running the program, it skips the first getline and goes straight to the second one.

I've tried std::cin, cin.ignore(), cin.sync(), and std::getline of course.

I have three files total. A header and class file, and a main file.
For showing what code matters, I'm only showing snippets of the class file and main file where the problem is involved at.

notebook.cpp

// -- snip --

Note Note::create_note() 
 Note s;
 std::string title;
 std::string note;
 std::cout << "nPlease enter the note's title: n";
 std::getline(std::cin, title);
 s.set_title(title);
 std::cout << "Please enter the note: ";
 std::getline(std::cin, note);
 s.set_body(note);
 std::cout << "Note added!nn";
 return s;


// -- snip --

tuffynotes.cpp

// -- snip --

char choice;
Note n;
// For storing up to 100 notes.
Note notes[100];
int size = 0;
// used for looping until user is done
bool flag = true;
int main() 
 while (flag) 
 std::cout << "Welcome to TuffyNotes!n";
 std::cout << "[C] Create a noten[L] List notesn[V] View noten[E] ExitnChoice: "; 
 std::cin >> choice;
 std::cout << "n";
 switch (choice) 
 case 'C':
 case 'c':
 notes[size] = n.create_note();
 size++;
 break;
 // -- snip --
 
 

The output says

Please enter the note's title: 
Please enter the note: 

when it should first allow me to input the title before skipping straight to asking for input for the body.

Please enter the note's title:

c++ cin

  Groovy. Thanks. You've run up against Why does std::getline() skip input after a formatted extraction? You have to be very careful when mixing >> and getline. If you need getline, it's generally better to only use getline and then parse the line into the stuff you want. std::stringstream often helps here.

  @user4581301 I'm assuming that you want me to replace the last two remaining cin statements in my code with getline statements. When I did this, I received an error. The cin statements were for an integer and for a character, and now they're giving m errors.

  Please make minimal reproducible examples. One for the already shown code (it could use some work on the "minimal" and one for the modified code. This also servers the general principle to add information to the question instead of hiding it in comments.

  When you entered the value read into choice, the newline was left in the input buffer. The first call to getline reads that newline, and is happy because it reached a newline. You are less happy, though.
