main函数形参argc和argv解析

int main(int argc,char* argv[])
{
    int count = 0;

    //获取终端输入指令
    for (; count < argc; ++count)
    {
        printf("%s\n", argv[count]);
    }
    printf("has %d orders\n", count);

    return 0;
}

/*程序执行结果
reacher@ubuntu:~/projects/proj$ ./server hello  reacher
    ./server
    hello
    reacher

    has 3 orders

综合代码和程序运行:
    argc    统计终端输入多少条指令
    argv    存储终端输入指令集
