What are the command line arguments in C and the arguments of methods in C?

statement in the defined variables!

In C, the parameters of the sail of the method trembling hail are divided into the following types:

Value parameter: Data of the value type passed to the method, such as int, float, double, bool, and so on. Changes to these parameters inside the method do not affect the caller.

Reference parameter: The data passed to the method is the reference type, such as class, array, delegate, and so on. Changes to these parameters inside the method affect the caller because they share a reference to the same object.

Output Parameter: The output parameter is used to return the value computed internally by the method, defined by the keyword "out". The caller needs to allocate memory space for this parameter before the method can assign a value to it.

Optional parameter: An optional parameter is used to define the parameters that a method can have a default value. This is defined by appending the parameter type with "=Default". The optional argument must be at the end of the method's argument list.

Parameter array: A parameter array allows a method to accept any number of parameters, which are encapsulated into an array. This is defined by prefixing the parameter type with the keyword "params".

The parameter array must be at the end of the method's argument list.

It should be noted that in the same method, it is not allowed to overload methods with only different parameter types. That is, if both methods have the same number of arguments and parameter type, then they are the same method.

Value type parameters: These parameters are copied and passed to the method, and modifications to the parameter values inside the method do not affect the original values. Common value type parameters include integer type (int, float, double, etc.), character type (char), and boolean type (bool).

Reference type parameters: These parameters pass references, and modifications to the parameter values within the method will affect the original code starting value. Common reference type parameters include arrays, class instances, strings, and so on.

Output Parameters: Output parameters are used to return multiple values from Akira Hashieda in the method. When the method is declared, it is used'out

Optional parameters: C and later versions support optional parameters. You can use the default value to provide a default value for a parameter when the method is declared. This allows you to omit some of the parameters when calling the method and let the method use the default values. Min.
