Storage classes specify the scope, lifetime and binding of variables.To fully define a variable, one needs to mention not only its ‘type’ but also its storage class.A variable name identifies some physical location within computer memory, where a collection of bits are allocated for storing values of variable.Storage class tells ...

We know that functions can be called by value and called by reference.If the actual parameter should not change in called function, pass the parameter-by value.If the value of actual parameter should get changed in called function, then use pass-by reference.If the function has to return more than one value, ...

Data structure is collection of data organized in a structured way. It is divided into two types as explained below −Linear data structure − Data is organized in a linear fashion. For example, arrays, structures, stacks, queues, linked lists.Nonlinear data structure − Data is organized in a hierarchical way. For ... Read More
