We know that, global variables are accessible in all other functions in c programming language, but we cannot access them normally in a function if function have the variables with the same names as the global variables. Let's consider the following example ...
In this program,Global variables are: a and bLocal variables are: x and yHere, a and b are using within the function setValues() and main() function because they are global and can be accessed anywhere. While x and y are using within the main() function only because they are local ...
CServer Side ProgrammingProgramming We will understand how C and C++ behave differently in case we re-declare a global variable without initializing, redeclaring global variables with initialization, redeclaring global variables and initializing them twice. Also, we will repeat above combinations with ...

This part of the code, where the global variables are declared. All the global variable used are declared in this part. The user-defined functions are also declared in this part of the code. Example: float a (float rd); int x;
you must declare all pointers to memory-mapped registers and global variables that are shared between threads (or a thread and an ISR) with the keyword volatile. And if you miss just one of them, Murphy’s Law will come back to haunt you in the final days of your project. I guarantee...

The variables defined in a function are external variables, and variables defined outside the function are called local variables, and the external variables are global variables (also known as whole variables). ~n ~~~7 Local variables can be shared by other functions in this document. Its ran...
