C 语言设计了"函数类型":"函数类型/function type" 用来描述, 说明为 return 类型的函数. 因此与 return 概念密切相关, 可以称为"返回(对象类型)的函数类型", 或者干脆说 "(被 return 派生的)函数类型".2. 表达式隐式进行"函数转换":表达式执行转换, 将"函数指明符/function designator" 的类型

int myFunction(int x, int y) { return x + y;}int main() { cout << myFunction(5, 3); return 0;} // Outputs 8 (5 + 3) Try it Yourself » You can also store the result in a variable:Example int myFunction(int x, int y) { return x + y;}int main() { int z = ...

Use Pointer to Pointer Notation to Return 2D Array From Function in C++ As an alternative, we can use a pointer to pointer notation to return the array from the function. This method has an advantage over others if the objects to be returned are allocated dynamically. Usually, one should mo...

A value-returning function will return a value each time it is called. Let’s take a look at a simple function that returns an integer value, and a sample program that calls it: #include<iostream>// int is the return type// A return type of int means the function will return some ...

result;}```在上面的例子中，`add`方法将两个参数相加，并将结果返回。注意，在Java中需要指定返回值的类型。3. JavaScript在JavaScript中，`return`用于从函数中返回一个值，并且可以指定返回的数据类型。例如：```javascriptfunction add(a, b) { var result = a + b; return result;}```在...
