What's the meaning of typecast?

Typecast means to convert from one type to other, eg, suppose we are storing an integer type in a string, we need to explicitly convert the int type to string.

In pure C, it is not necessary to typecast malloc. However, you will have to typecast it if you want to access that value pointed to by the pointer. There will be no compiler error anyhow.

malloc return a generic type pointer.Because generic pointer is of type void (void *p,p is generic pointer).Void pointer can hold any type of data so it is needed to typecast it.

Explain malloc and calloc functions in c.

malloc returns generic pointer(void *). So no need to typecast at all. It's not mandatory and there is no wrong if we typecast.

Actually its true! Its not necessary in C but in C++ its necessary. If you want your program to be generic (portable) then better you typecast it properly.

Type casting is a way to convert a variable from one data type to another data type. For example, if you want to store a long value into a simple integer then you can type cast long to int.
