Briefly explain local variables
In the programming language,
A variable is used to store some value.
The value store in the variable may change during the execution of the program.
A variable can store letter, string, number, floating-point number, the Boolean value depending on the data type.
Variables are declared in the program before using them.
The declaration of the variable is used to define the type, size, and scope of the variable.
The variable declaration is used to allocate the space in the memory.
A variable has a scope. The scope of the variable is the lifetime of the variable in a program.
A variable can be used multiple times in a program.
The syntax to declare a variable is:
datatype variableName;
For example:
int x;
string str;
if you want to assign a value to the variable at the declaration time then the variable declaration syntax is:
datatype variableName = value;
For example:
int x = 10;
string str = “Some Data”;
