If you want to use a class in multiple files, you should put the class definition in a header file and define the class methods in a corresponding source file. (You an also useinline functionsfor the methods.) If you want to use a variable in multiple files, you should put the declara...
C Library and User Define Functions (UDF)Functions play a very useful role in modular programming, functions are also known as modules. A function is a set of statements which performs specific task.In Modular Programming, a program can be divided into modules, these modules are kno...
Functions In Python Python comes with a number of inbuilt function which we use pretty often print(), int(),float(), len() and many more. Besides built-ins we can also create our own functions to do more specific jobs, these are called user-defined functions ...
‘#define’ directive is written to initiate a macro. Arguments can also be sent to macros. Macros with parameters behave in the same way as functions do. When the compiler encounters a macro name, it substitutes the name with the macro’s definition. Semi-colon does not have to be used...

So far we have looked at functions with empty parentheses that do not take arguments, but we can define parameters in function definitions within their parentheses. Aparameteris a named entity in a function definition, specifying an argument that the function can accept. In Go, you must specify...
For example, I have following use case. There are bunch of helper functions in func.m file, which will use some global variable const. How can I declare them once, such that all helper functions in this function file can use them?
functionS = myConst() S.a = 2; S.b = 7; S.c = 15; S.name ='My Name'; S.age = 105; end When you call this function it will return a structure with all of the given variables in it. This is trivial to use: S = myConst(); ...
