where, data_type is a valid data type (along with datatype modifiers, if required) and var_name is the name of the variable.
marks is the name of the variable, and it can store values of
Once we have declared or created the variable, then we can assign a value to it. This is called variable definition.
// variable declaration int marks; // variable definition marks = 10;
We can do declaration and definition in a single step too, like this (recommended).
int marks = 10;
