有关C++的输入cin,getline,get, 大家是不是都明白了?这个东西看其来是不难,但是你如果不是很留心,马上就会出错的。呵呵!
现在给大家一个C++程序。^_^!大家先看看CPP程序,想一下程序运行结果,然后在C++编译器里编译一下。看看你想的和你运行的结果是不是一样??
// strtype4.cpp -- line input
#include <iostream>
#include <string> // make string class available
#include <cstring> // C-style string library
int main()
{
using namespace std;
char charr[20];
string str;
cout << "Length of string in charr before input: "
<< strlen(charr) << endl;
cout << "Length of string in str before input: "
<< str.size() << endl;
cout << "Enter a line of text:\n";
cin.getline(charr, 20); // indicate maximum length
cout << "You entered: " << charr << endl;
cout << "Enter another line of text:\n";
getline(cin, str); // cin now an argument; no length specifier
cout << "You entered: " << str << endl;
cout << "Length of string in charr after input: "
<< strlen(charr) << endl;
cout << "Length of string in str after input: "
<< str.size() << endl;
return 0;
}
