1 eatwhite

Ignore leading spaces

2 Gcount

Count the last characters entered

3 Get

Extracting characters from a stream, including spaces

Std::cin.get (CH);//equivalent to Ch=std::cin.get;

Interview, compound expression

4 Getline

Extracts a line of characters from a stream

Std::cin.getline (str, 10);//Limit length, save 10-1 = 9 characters, last character is ' + ', function: Limit the length of the input password, prevent buffer overflow

1#include <iostream>2 3 voidMain ()4 {5     Charstr[ -] = {0 };6 7Std::cin.getline (str,Ten);//Limit length, save 10-1 = 9 characters, last character is ' + ', function: Limit the length of the input password, prevent buffer overflow8 9Std::cout <<str;Ten              OneSystem"Pause"); A}

5 Ignore

Extracts and discards specified characters in a stream

6 operator>>

Extraction operators

7 Peek

Returns the next character in the stream, but does not remove it from the stream

8 Read

Unformatted Input byte count

9 SEEKG

Move the input stream pointer

Ten TELLG

Returns the pointer value for the specified position in the input stream
