returnType functionName(parameter1, parameter2, parameter3) { // code to be executed}In the example below, the function takes a string of characters with name as parameter. When the function is called, we pass along a name, which is used inside the function to print "Hello" and the nam...
Create a Function To create (often referred to asdeclare) your own function, specify the name of the function, followed by parentheses()and curly brackets{}: Syntax voidmyFunction() { // code to be executed } Example Explained myFunction()is the name of the function ...
https://en.cppreference.com/w/c/language/variadic 参数可变函数 The declaration of a variadic function uses an ellipsis as the last parameter, e.g. int printf(const char* format, ...); See variadic arguments for additional detail on the syntax and automatic argument conversions. 参数可变函数...

all parameter checking is turned off. This special meaning of the empty argument list is intended to permit older C programs to compile with new compilers. But it’s a bad idea to use it with new programs. If the function takes arguments, declare them; if it takes no arguments, use void...
If the S-function parameter count passes, mdlInitializeSizes next sets the number of continuous and discrete states using ssSetNumContStates and ssSetNumDiscStates, respectively. This example has zero continuous states and two discrete states. Next, the method configures the S-function to have a...
If the direct-declarator includes a parameter-type-list, the list specifies the types of all the parameters. Such a declarator also serves as a function prototype for later calls to the function.A declaration in the declaration-list in function definitions can't contain a storage-class-specifier...
