Return from void functions in C - The void functions are called void because they do not return anything. “A void function cannot return anything” this statement is not always true. From a void function, we cannot return any values, but we can return
Void as a Function Parameter The void can also appear in the parameter list part of the code to indicate the function takes no actual parameters. C++ can take the empty parentheses, but C requires the word "void" in this usage. In C, the code takes the form: void printmessage (void )...

Another use of void pointers in C is infunction pointers, which are variables that store the memory address of a function. Void pointers can be used to store the memory address of any function, regardless of its return type or parameter list, allowing for more flexibility in function pointer ...
In this lesson, we’ll explore functions with a return type of void. Void return values Functions are not required to return a value back to the caller. To tell the compiler that a function does not return a value, a return type of void is used. For example: #include <iostream> //...

调用void in - C 编程语言 在C语言中,定义函数时可以指定函数的返回值类型,即函数结束时返回给调用者的值。有时候,我们需要定义一个函数,在函数中执行某些操作,但没有需要返回的值。 这时候,我们可以使用 void 关键字来定义这样的函数。void 表示函数没有返回值,因此在函数定义中不需要声明返回值类型。 以下是...
