Do you know what is the difference between 'gets' and 'cin' in C++?

Answer 1

cin is a static object of the istream class, defined in the iostream header file. It is used for taking user input, like so:

int a;
cin >> a;

You can use it for taking input for any datatype by overloading the right-shift operator (>>) accordingly for that datatype. You don’t need to do this for primitive types like int, float, char etc.

gets is a function, defined in the stdio.h header file. gets is used for taking string input, like so:

char t[100];
gets(t);

Although you can use cin for taking string input too, the input string will be truncated at the first white-space character.

Also, gets is now deprecated, meaning that future versions of C/C++ may not support it. This is because it does not check for buffer overflow. You may want to have a look at the fgetsfunction.

Cin>> is the best 😇😘
