The simple answer is you don't. The primary purpose of a flowchart is to show the flow of execution through an algorithm, with all primary functions and decisions described in broad, abstract terms.
There is no need to distinguish between local and global variables because that is an implementation detail -- it's far too low-level a concept for algorithm design.
All variables utilised by an algorithm should essentially be declared up front at the start of the flowchart and should therefore be treated as being local to that particular flowchart. It doesn't matter where those variables came from, only that they be initialised accordingly. The decision to make a variable global comes much later, once the interactions between different flowcharts have been established. Even so, a global variable should only ever be considered when the variable represents a truly global concept. In the vast majority of cases, passing arguments into functions is often the better option. Especially when separate algorithms are intended to run concurrently because making a global variable thread-safe can seriously impact performance. But this is not a concern in algorithm design, they are only of importance to the implementers; the class designers.

whose variables are also known as global variables?
The variables which are declared outside the main() function is known as global variables and they can be used anywhere in the program. And, the variables which used declare inside the main() function is known as local variables and they can be used inside the main() function only. Example: #include<stdio.h> #include<conio.h> int x,y; // global variables void main() { int a,b; // Local variables ------------ ---------------------- --------------------- getch(); }
How do you declare local and global variables in pseudo code?
Pseudocode is not a programming language (it's specifically intended for human interpretation), so there is no need to declare variables, you simply define them as and when you require them. For instance: Let x = 42 Let y = x * 2
Are C variables initialized to 0 by default?
Only global/static variables are, local variables aren't.
Why all variables are declared with in the function?
It is not necessary to to declare variables inside the function in C. If you declare a variable inside a function, the variable becomes local for the function and another variable of same name can be declared in any other function, but you can not use the variable declared in other function. When you declare any variable outside the function body then the variable becomes global and can be used in any function of the program. Note: errno is an example for a variable declared outside any function.
What are local variables and global variables?
Local variables: These variables only exist inside the specific function that creates them. They are unknown to other functions and to the main program. As such, they are normally implemented using a stack. Local variables cease to exist once the function that created them is completed. They are recreated each time a function is executed or called. Global variables: These variables can be accessed (ie known) by any function comprising the program. They are implemented by associating memory locations with variable names. They do not get recreated if the function is recalled.

What are the differences between global variables and local variables in C plus plus?
Global variables can be seen in all blocks of your program, when local variables are visible only within the block where it's declared.
Are C variables initialized to 0 by default?
Only global/static variables are, local variables aren't.
How do you hide local variables in c and give precedence to global variables inside the function?
Hi, I would like to answr the question.So, if you want the to give more precedence to global variables with respect to a local one.Just add a pair of curly braces in the local variable and by doing so u can access global variable.
If most variables are local in a program instead of global the result is a program with low or high coupling?
Coupling is the interdependency of a program. A program that uses local variables is more independent than one that uses global variables. Therefore, the program would be considered to have lower coupling.
When is better to use global variables rather than utilizing local variables in a program?
In my opinion it is rarely a good idea to use global variables, unless you need to refer to them across modules, or their values need to be keep for a long period of program execution. Local variables should always be used when their lifetime is short, usually only in the module they are declared in. Global variables lifetime will be for the length of the program execution.
What is the difference between a static variable a global variable and a local variable?
A static variable is a variable allocated in static storage. A local variable is a variable declared inside a function. A global variable is a variable declared outside of any class or function. Note that local variables and global variables can both be allocated in static storage.
What is the difference between global variable and extern variable?
Global variables are non-local variables. That is, variables that are not defined in a function or class. They are globally accessible to all code in the same translation unit. External variables are global variables that have external linkage; they are accessible across translation units.
What is the difference between declaring static variable as local and global?
There are two ways to declare varibles. 1. Locally 2. Globally When you declare a variable locally in any function that means it is only accessible by that function. When you declare a variable globally so it is accessible by all the functions in the program. Declaring variables with static keyword means you are setting its value null.
Why all variables are declared with in the function?
