In C programming, you have the option to initializevariablesalong with their declaration. Initialization means assigning a default value to a variable. For example,“int z = 0;”initializes an integer variable named“z”with a default value of 0. Initializingvariablescan help prevent them from c...
I would like to define variable in the top of my VBA to reference file and range (column) to make then Index/match function. Defining variable at the top of my code will be more convenient to update my code later on. However, I always face an error message on this line: R...
A variable can be declare/define in a C Header without any kind of compilational/ logical errors. But it is against the coding specifications and it is not normally practiced. If proper Multiple inclusion protection macro is used, then there will be no problem even the header is included in...

Code that needs to know the details of what is in MyClass can't work--you can't do this: class MyClass; MyClass an_object; class MyClass { int _a_field; }; Because the compiler needs to know the size of the variable an_object, and it can't do that from the declaration of ...
ISPF provides the binary string data format to support dialog applications written in the C language. When a variable defined as BINSTR is updated in the function pool, ISPF pads with binary zeros. This is desirable within C function programs, because the C language uses binary zeros to mark...
In your handler code, you can reference any environment variables by using the System.Environment.GetEnvironmentVariable method. In this example, we reference the defined RECEIPT_BUCKET environment variable using the following lines of code: string? bucketName = Environment.GetEnvironmentVariable("RECEIPT...
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?
