Why cin method in cpp dont take spaces as input?

Question

When i declare a string 's' in cpp and then gets input by cin and let user enters : ram 45 cat
then cin only get ram not spaces and characters after it?

Answer 1

If using getline(), make sure you know which one you're using.

c++ string in <string>
http://www.cplusplus.com/reference/string/string/getline/

c string (char* array) in <iostream>
http://www.cplusplus.com/reference/istream/istream/getline/

Answer 2

Use: getline(cin,s);

Answer 3

'cin' is the functions which gets input till it reads a space, so to get the characters after space we generally use gets function.
