First write the data type for the variable, such as int, float, double and then write the variable name such as a, b, c or your name or anything except the keywords. And then write the value of your variable such as 5 or 500 or 2000.
For example:
int a = 5;

float b = 4.0;

[storage class] data_type variable_name [= value] // [ ] = optional

In C: type_name = value; e.g. int a;

In PHP: $name = value; e.g. $a; //No need to declar the type in PHP

Storage class = static, protected, private, public etc

depends on the language but generally you do:

<variable type> <variable name> (you can add =<some initializer> if you want) ;

example:

int num = 0;

string name;

bool flag;
