Message: [QUOTE="v32457_p, post: 8381, member: 5"] Local and Global Variables Local and Global Variables define the scope and lifetime of data within a program. A Global variable is declared outside any function or block and can be accessed and modified from any part of the code. They exist for the entire duration of the program. While convenient, overuse can lead to naming conflicts and make code harder to debug. A Local variable is declared inside a function or block. It can only be accessed within that specific scope. Once the function or block finishes execution, the local variable is destroyed. This limits its effect, preventing interference with other parts of the program and promoting cleaner, modular code.
