This function tells the cin object to skip one or more characters in the keyboard buffer.

Select one:
a. cin.ignore
b. cin.jump
c. cin.hop
d. cin.skip;
e. None of these

Answer 1

The correct option is 'a. cin.ignore' which is used in C++ programming to ignore characters in the input buffer.

Step-by-step explanation:

Ignore function is used to skip(discard/throw away) characters in the input stream. Ignore file is associated with the file istream. Consider the function below ex: cin. ignore(120,'/n'); the particular function skips the next 120 input character or to skip the characters until a newline character is read.

In general, if we want to immediately throw away the newline that follows using cin to not mess things up when we later use getline, then use cin. ignore() immediately after a “cin >>” to discard the next value. The function that tells the cin object to skip one or more characters in the keyboard buffer is cin.ignore.

This function is used in C++ to ignore characters that are entered by the user and remaining in the input buffer. By default, cin.ignore() skips one character, but you can specify the number of characters to skip and an optional delimiter as arguments to the function. For instance, cin.ignore(100, '\\') will ignore up to 100 characters or until a newline character is encountered.
