getline() and write() functions are multi character functions.
1. getline(): It reads a line of text that ends with a newline character. It reads white spaces also.
Eg. char line[80];
cin.getline(line,80);
2. write():
It is used to display a string.
Eg. charline[80];
dn.getline(line, 80);
cout.write(line, 80);
