• Enhanced performance and efficiency

    • Opportunities and realistic risks

    Variables are containers that hold values in a program. They are assigned a name, which can be used to refer to the value stored within. The purpose of variable definition is to declare the type and scope of the variable, allowing the compiler to check for errors and ensure that the code is correct. Variable definition involves specifying the data type, name, and initialization value of the variable. For example:
