将开发过程比较重要的一些内容段做个记录，下面内容段是关于C++编写的一个简单的猜数字游戏的内容。

#include <iostream>#include <string>#include <cstdlib>#include <cctype>#include <ctime>#include <conio.h>using namespace std;int main (){ int wins = 0; int losses = 0; int tries = 0; int guess; unsigned int number; char playAgain = 'Y'; srand((unsigned)time(NULL)); number = rand() % 101; while (toupper(playAgain) == 'Y') { while (tries < 21) { cout << "Enter a number between 0 and 100: "; cin >> guess; if (guess == number) { wins = wins + 1; break; } else tries = tries + 1; } if (tries > 20) { losses = losses + 1; cout << "Try Again "; } else cout << "You won! "; cout << "Want to play again?"; cin >> playAgain; } cout << "Your total wins: " << wins; cout << " Your total losses: " << losses;getch();return 0;}
