相信大家用C语言定义main函数时，大多数人的写法都是int main(void)。其实main函数是可以向其传递参数的，给个实例：

//给main函数传参实例：

#include
#include

//int main(int argc, char *argv[])
int main(int argc, char **argv)
{
char *array[3] = {"./main", "hello", "world"};

if (argc < 2)
{
printf("error!\n");
printf("./main str\n");

return -1;
}

printf("The first string of your command is:%s\n", argv[0]);
printf("The second string of your command is:%s\n", argv[1]);
printf("The third string of your command is:%s\n", argv[2]);

if (!strcmp(argv[0], array[0]))
{
printf("The first command execute successfully!\n");
}
if (!strcmp(argv[1], array[1]))
{
printf("The second command execute successfully!\n");
}
if (!strcmp(argv[2], array[2]))
{
printf("The third command execute successfully!\n");
}

return 0;
}

输出结果：
（1）若输入命令为：./main
则输出结果为：
error!
The command is:./main
（2）若输入命令为：./main hello world
则输出结果为：
The first string of your command is:./main
The second string of your command is:hello
The third string of your command is:world

The first command execute successfully!
The second command execute successfully!
The third command execute successfully!

大家可以利用这个程序模型干很多事呢！
