variable exit within a function and curly braces is local variable
int main()
{
int x;
}
A local variable is a variable declared inside a construct, such as a class or function, while a global variable is a variable declared outside of any construct.
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
Variable declaration is when you declare a variable. For example: String foo; The data type is String and now I can modify foo and don't need to type String again. It can be an instance variable or a local variable.
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.
When you declare a variable and it's data type in a function, it is stored in the specific space for memory allocated by the variable type identifier known as the "stack."
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.

A local variable is a variable that can only be called on by the module. Where as a global variable can be called upon by any module. Only statements made inside the same module can call on a local variable.
A variable declaration is a math or programming term. A variable is an unnamed component. In the problem the wording will declare what the value of the variable is.
you have to give a statement in the following syntax datatype variable;
To declare a double precision variable in Fortran, you can use the "real(kind8)" declaration. This specifies that the variable should be of double precision, which is typically 8 bytes in size.
