When to Use Enum in C Enums in C are used to define a set of named integral constants that represent a set of related values. Here are some situations where enums are commonly used: Improving Code Readability: Enums make code more readable by providing descriptive names for integral constan...

To find the value of B5, enter the formula in B8: =INDIRECT("B5") Example 2 – Using the Ampersand to Define the Row and Column Index with the INDIRECT Function To find the value of C8, enter the formula in E7: =INDIRECT("C"&8) Example 3 – Using the ROW Function inside the...
It is important to note thatvariablesin C programming must bedeclaredanddefinedat the beginning of a program or function. This is known as thevariable declarationsection or scope of the program, and it ensures that all variables are properly initialized before they are used in any operations. Co...
In this example, we define a function initializeStudents that takes a pointer to an array of Student structs and the number of students. The function prompts the user to enter the details for each student. This approach separates the logic of initialization from the main function, improving code...
Use Standard Notation to Return a Struct From a Function in C The struct keyword in C is used to implement user-defined data structures. Since we define the struct type in this example, it will be a cleaner notation for function declarations if we typedef the MyStruct structure. It will ...
When a user frequently uses a command or some commands, the user can use shortcut keys to define these commands. Only management-level users have the rights to define shortcut keys. The configurations are as follows: Run the system-view command to enter the system view. Run the hotkey {...
