Difference Between Enum and Macro Example of Enum Example of Macro Conclusion Learn the fundamentals of C by watching the video below: What is Enum in C? In C programming, an enum (enumeration) is a user-defined data type that is used to define a set of named integral constants; these...
But what if your float value is defined as another macro expression? In this case, you’ll need to use a two-level macro approach to ensure the correct conversion. Consider this example: #include<iostream>#include<string>using std::cout;using std::endl;using std::string;#defineSTRINGIFY(x...
Normally, there aren’t any object files in source code distributions, but you might find some in rare cases when the package maintainer is not permitted to release certain source code and you need to do something special in order to use the object files. In most cases, object (or binary ...
Before we can filter a vector of custom structs, we need to define what our struct looks like. Let’s create a simple struct called Person that has a name and an age. struct Person { name: String, age: u32, } fn main() { let people = vec![ Person { name: String::from("Alice...

1. The Concept of C Macros Macros are generally used to define constant values that are being used repeatedly in program. Macros can even accept arguments and such macros are known as function-like macros. It can be useful if tokens are concatenated into code to simplify some complex declarati...
Name the macro,Concatenate_StringIntegerPlus(). Define the variablesStr1, Str2, Int1,andResultand assign theIntegerandStringdata types. Store the values of theD5andF5cells in theStr1andInt1variables. Use theCStr functionto convert theInt1variable to a string and store it in theStr2variable...
Order1:=xlAscending→ Sorts the column in ascending order. Use xlDescending for descending order. Header:= xlNo→ Since the column has no header, we set this option. Press F5 or click the Run Sub/UserForm icon to execute the macro. Your column will be sorted in ascending order. Note tha...
