What is an integer variable?

Inccessive variable is the type of numeric variables in computer programming designed to store the whole number. This differs from other types of numerical variables in that it cannot store decimal values. It is not possible to use integer variables such as text or boolean variables to store values ​​of another data type.

The integer variables are useful if the programmer needs to extract only an integer from an existing number with a decimal value. If the decimal value is expected but is either external or undesirable, the value can be placed in the entire variable. This automatically destroys the decimal part of the value. Variables

in computer programming work in almost the same way as the variables work in algebers. Traditional name algebra variables can be "x" or "y." They represent an unknown value that can later be determined by calculations. One of the main differences between algebraic and programming variables is ER complication languagesEnter the name of the variable to the programmer. This name can be "x", "y" or other name that gives a clearer indication of what the variable represents.

Variable computer programming All storage of different types. These data types determine how to handle the variable. Logical calculations designed for an integer variable cannot be done on text chains or Boolean variables. On the other hand, the integer variable does not allow logical calculations suitable for types of non-semheric variables.

6 This means that the programmer must specify that the variable it declares is an integer. The programming language can use a specific keyword designed for this purpose. For example, the keyword for declaring an integer variable into C ++ is "int".

in programming languages ​​such as Perl, variables may not be declared nor have the type specified before using variables. HammerThe urchin or compiler determines the type of variable according to the operators used on the variables. For example, the pearl uses an operator == to determine whether two numeric values ​​store exactly the same information. The "EQ" operator determines whether two variable text strings contain identical data.

Determination of types of variables can cause problems, occupy multiple system resources and can also slow the program. Therefore, most languages ​​require explicit variable statements.
