Cin.ignore() related question

#1

My question is what is the cin.ignore() line does and how can I predict when I will need to use cin.ignore()?
In my program I used the below statement

cin.ignore(1000, ‘\n’);

so what is 1000 here and ‘\n’.

Hello @Satyam_singh
numeric_limits sets the maximum number of characters to ignore.
‘\n’ sets the delimiter, i.e. the character after which cin stops ignoring.
so in this:
cin.ignore(1000, ‘\n’);
it will ignore first 1000 characters.
