表达式由数据结构、绑定的变量(即具有值的变量)、数学操作符和函数调用 组成。 The expression is composed of data structures, bound variables(that is, those with a value), mathematical operations and function calls . 跳转语句break、continue、goto和return表达式,其中表达式不含函数调用 。 The jump statements break, continue, goto, and return expression, where expression does not contain a function call . 表达式的基础由文字(比如674、3.14、true和‘X')、变量和函数调用 组成。 The basic building blocks of expressions are literals(such as 674, 3.14, true, and'X'), variables, and function calls . 比如,对std::vector类型来说,v2=v1通常包含一次函数调用 、一次内存分配和一个循环。 For example, for std::vectors, v2=v1 typically involves a function call , a memory allocation, and a loop. 如果你正在做BPM,然后只是说“步骤=服务”;然后你就开始做VISUALCobol,用服务替换掉函数调用 。 If you are doing BPM and then just saying"step= service" then you are doing VISUAL Cobol and replacing function calls with service.
习题4.2将上面程序的最后一行调到最开始,这样函数调用 就出现在函数定义之前。 Exercise 3.1 Move the last line of this program to the top, so the function call appears before the definitions. 任何产生值的东西都是JavaScript中的表达式,这意味着可以在较大的表达式中使用函数调用 。 Anything that produces a value is an expression in JavaScript, which means function calls can be used within larger expressions. X里面唯一的不同,是里面的print表达式应该是函数调用 的方式(print(numbers))。 X, in which the only difference, is inside the print expression should be a function call .(print(numbers)). 静态变量仅在函数中首次定义,并且其值可以在函数调用 期间进行如下修改:. A static variable is defined within a function only the first time, and its value can be modified during function calls as follows. 这个语法更加简洁,和替代array()的[]一样,这个新的语法不像是函数调用 。 This syntax is more concise, and like the[] alternative to array(), this new syntax does not resemble a function call . 对于普通的函数调用 ,函数的返回值成为调用表达式的值。 For regular function invocation , the return value of the function becomes the value of the invocation expression. 正如你所看到的,这两个函数调用 finish来执行onDestory方法,从而关闭应用程序。 As you can see, both functions call finish to execute onDestory method, which closes the application. 这里,在函数调用 的参数数目应当与函数定义完全匹配。 Here the number of arguments in the function call should match exactly with the function definition. 如果构造函数调用 非final方法,则子类可能会以令人惊讶的或不希望的结果重新定义该方法。 If a constructor calls a non-final method, a subclass may redefine that method with surprising or undesirable results. 这意味着您正在进行函数调用 (几个cpu周期)并将其转换为网络调用。 This means that you are using the function call (several CPU cycles) into a network call. . 当函数调用 另一个函数时,为该调用创建一个新的本地符号表。 When a function calls another function, a new local symbol table is created for that call. . 这意味着您正在进行函数调用 (几个cpu周期)并将其转换为网络调用。 This means you are taking what was a function call (a couple cpu cycles) and turning it into a network call. . 栈:保存函数调用 时的返回地址、函数的形参、局部变量,以及CPU的当前状态。 Stack: Holds the return adress of function calls , arguments to functions, and local variables, also used to save the current state of the CPU. 函数调用 或重载运算符表达式,其返回类型是非引用,例如str.A function call or an overloaded operator expression, whose return type is non-reference, such as str.类似函数调用 ,服务通过返回动作相关的值来回应控制消息。 Much like function calls , the service returns any action-specific values in response to the control message.
