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.
char line[80];
cin.getline(line,80);
cout.write(line,80);
