[File Operate] XXXX

Description: C语言编程宝点之XXXX main()主函数 每一C 程序都必须有一main()函数, 可以根据自己的爱好把它放在程序的某 个地方。有些程序员把它放在最前面, 而另一些程序员把它放在最后面, 无论放 在哪个地方, 以下几点说明都是适合的。 1. main() 参数 在Turbo C2.0启动过程中, 传递main()函数三个参数: argc, argv和env。 * argc: 整数, 为传给main()的命令行参数个数。 * argv: 字符串数组。 在DOS 3.X 版本中, argv[0] 为程序运行的全路径名 对DOS 3.0 以下的版本, argv[0]为空串(\"\") 。 argv[1] 为在DOS命令行中执行程序名后的第一个字符串 argv[2] 为执行程序名后的第二个字符串 ... argv[argc]为NULL。 *env: 安符串数组。env[] 的每一个元素都包含ENVVAR=value形式的字符 串。其中ENVVAR为环境变量如PATH或87。value 为ENVVAR的对应值如C:\\DOS, C: \\TURBOC(对于PATH) 或YES(对于87)。 Turbo C2.0启动时总是把这三个参数传递给main()函数, 可以在用户程序中 说明(或不说明)它们, 如果说明了部分(或全部)参数, 它们就成为main()子程序 的局部变量。

4 {
5     QApplication app(argc, argv);
6     QLabel *label = new QLabel("Hello Qt!");
7     label->show();
8     return app.exec();
