If a numeric parameter immediately follows the control word, this parameter becomes part of the control word.
如果一个数值参数紧跟着控制字,这个参数就是控制字的一部分。
Note that a numeric addition has occurred because the input parameter to the add function is bound to an int type argument at function execution time. Now, try this.
请注意,由于add函数的输入参数在运行时被绑定到int类自变量,因此产生了数值的增加。
The only part remaining is the handling of error reporting (such as an unknown parameter flag character or a numeric value out of range).
最后剩下的部分就是处理错误报告(例如一个未知的形参标记字符或者一个超出范围的数字值)。
