cin.get(字符数组，数组大小，分隔符)与cin.getline(字符数组，数组大小，分隔符)区别
#include <iostream.h>
以下两个程序输出是一样的，那两个方法cin.get与cin.getline（都带三个参数的时候）是一样的吗？
程序一：
#include <string.h>
void main()
{
const int size=80;
char buffer1[size];
cout < < "input a sentence: " < <endl;
cin.getline(buffer1,size, ' ');
char c=buffer1[0];
for(static int n=0;c!= '\0 ';n++)
{
c=buffer1[n];
cout < < "the string read with cin.get is: " < <buffer1[n] < <endl;
}
}
程序二：
#include <string.h>
void main()
{
const int size=80;
char buffer1[size];
cout < < "input a sentence: " < <endl;
cin.get(buffer1,size, ' ');
char c=buffer1[0];
for(static int n=0;c!= '\0 ';n++)
{
c=buffer1[n];
cout < < "the string read with cin.get is: " < <buffer1[n] < <endl;
}
}
麻烦解释的详细点。

自己看吧
istream_type&
get(streambuf_type& sb,char_type delim);
Extracts characters and inserts them in the output sequence controlled by sb. Characters are extracted and inserted until any of the following occurs:
An end-of-file on the input sequence
A failure when inserting in the output sequence
The next available input character == delim.
An exception
If the function stores no characters, it calls the basic_ios member function setstate(failbit), which may throw ios_base::failure. If failure was due to catching an exception thrown while extracting characters from sb and failbit is on in exception(), then the caught exception is rethrown.
----------------------------------------------
istream_type&
getline(char_type* s, streamsize n, char_type delim);
Extracts characters and stores them into successive locations of an array whose first element is designated by s. Characters are extracted and stored until any of the following occurs:
n-1 characters are stored
An end-of-file on the input sequence
The next available input character == delim.
If the function stores no characters, it calls the basic_ios member function setstate(failbit), which may throw ios_base::failure. In any case, it stores a null character into the next successive location of the array.

cin.get()第一个用法，是读入一个字符。
cin.get()第二个用法，也是输入一行（同cin.getline()），但是区别就是，不输出分隔符~
getline默认情况下以回车( '\n ')作为结束,输入一行
