The command line arguments are handled using main() function arguments where argc refers to the number of arguments passed, and argv[] is a pointer array which points to each argument passed to the program. Following is a simple example which checks if there is any argument supplied from the...

$ ./repeat.exe Resistance is futile The command line has 3 arguments: 1: Resistance 2: is 3: futile 我这里的运行环境是windows下Cygwin模拟的命令终端的运行结果。其他环境输出结果是一样的。 运行原理: C编译器允许main()函数没有参数或两个参数(一些实现允许main()有更多参数,属于对标准的拓展)。main...
在编译并运行程序前,我们还需要在Qt Creator中做一些设置,以便指定程序运行的参数。在Qt Creator中选择“项目”页,在“运行设置”中将Command line arguments设置为33 777 103,这相当于给应用程序提了以空格分隔的三个参数,分别为33、777和103,如图6-7所示。请注意图中箭头以及黑色方框标识的内容。
