newValues.a = 1; // Some new value. newValues.b = 2; // Another new value. return newValues; // Return a struct containing both values. } int main() { Pair values = getNewValues(); // Access returned values from
A function can be defined to accept one or more than one arguments, it is able to return a single value to the calling environment. However, the function can be defined to return an array of values. In C, a function can be made to return an array by one of following methods −...
the function body is the lines of code executed when the function is called and the return type is the type of value returned to the calling function. However, at times we need to return multiple values from a function

Return ValuesThe void keyword, used in the previous examples, indicates that the function should not return a value. If you want the function to return a value, you can use a data type (such as int or float, etc.) instead of void, and use the return keyword inside the function:...

永不返回的函数有一个特殊的返回类型!,称为 "永无类型(Never type)"。这类似于C语言中的noreturn注解。然而,使用类型为!的表达式必然是死代码,因此,!将隐含地强制到所有类型(这简化了类型检查,并且完全没有问题,因为这都发生在可证明的死代码中)。
The Simulink engine calls the mdlUpdate function once every major integration time step to update the discrete states' values. Because this function is an optional method, a #define statement must precede the function. The beginning of the function obtains pointers to the S-function discrete states...
2) Return type and value of scanf scanfis a library function ofstdio.h, it is used to take input from the standard input device (keyboard). scanfreturns an integer value, which is the total number of inputs. For example:if you are reading two values fromscanf, it will return 2. ...
