Introduction to Variables
In the realm of programming languages, variables play an important role in storing and manipulating data. The process of creating a variable involves two essential steps: declaration and initialization.
- Declaration: the process of introducing a variable to the compiler. It involves specifying the variable's data type and, optionally, giving it a name;
- Initialization: the process of assigning a value to a declared variable. It is crucial to prevent the variable from containing unpredictable or garbage values.
main.cpp
Note
You can provide an initial value to the variable at the time of declaration.
Also when declaring multiple variables that hold the same type of data, it is convenient to specify the data type only once.
Naming Conventions
Choosing meaningful and descriptive names for variables is crucial for writing maintainable and understandable code.
Variable names in C++ can consist of letters and numbers but cannot start with numbers, nor can they contain spaces or arithmetic operators. Also avoid using names that coincide with reserved keywords. This can lead to compilation errors.
