進階程式設計 12/26 練習五

#include<iostream>
#include<cstdlib>
#include<cstring>
using namespace std;


//主程式
int main()
{
    int a = 1023;  //宣告變數
    float b =23.45;
    char *str = "菜牛牛\n";

    //輸出字串內容
    cout << str;

    //輸出整數,浮點數和運算式
    cout << "a = " << a << endl;   //endl 換行  意思
    cout << "b = " << b << endl;
    cout << "a + b = " << a+b << endl;

    cout.put('a'); //put()成員函數
    cout.put('b').put('c');
    cout << endl;

    cout << strlen(str) << endl;    //字串長度
    cout.write(str, 2);  //write()成員函數
    cout << endl;

    cout.write(str,strlen(str)-1);
    cout.write(str,strlen(str));

  system("PAUSE");
  return 0;
