They are entirely different things; int is a type, typedef is a way to define types.

Typedef int a a a Is this possible in C?
No, but 'typedef int a;' is possible, it defines the type 'a'.
What is meant by array with in structure in c language?
It means a structure has a member that is an array: typedef struct foo { int x[42]; // an array of 42 integers // other members... };
How do you declare data types?
typedef data_type data_name, for instance:typedef int myDataType;
How typedef feature used with structure?
You use typedef to declare a synonym for an existing type. It's generally just a way of reducing a complex or cumbersome declaration outside your code to a more simplified, more easily understood declaration that you can use inside your code.Cumbersome example:void DoStuff( void (*)(int&, char& ), int&, char&); // Huh? Do what?Simplified example:typedef void (*pFunc) ( int&, char& );void DoStuff( pFunc, int&, char& ); // Aha! It's a function pointer!In relation to C structures, typedef provides a way to declare and name user-defined types, primarily so you don't have to use the struct keyword in the variable declaration. C++ structures are more flexible and the typedef keyword is optional.Structure examples for C:struct hard{ int i;double f;};// typedef is optional in C++, but required in C.typedef struct{int i;double f;} easy;int main(){struct hard hs; // Requires struct keywordeasy es; // Same as C++.}
What are the different types of integer constants in c language?
Well, uh, const unsigned int and const signed int..
Int a is literal in C language or not?
int a; -- variable definition"int a" -- string literal
What is the main use for type def seems to be defining structures?
When you define a structure, C does not provide a type for that structure. In order to subsequently declare an instance of that structure, you need to use the word struct again. The typedef allows you to declare a type equivalent to the structure. For example... struct person { char* name, int phone}; struct person myperson; With typedef, you can simplify to... typedef struct person { char * name, int phone} person;person myperson; In C++, this is automatic, but not in C.
Why should you use typedef in c language?
For no other reason than that it is required whenever you declare a type definition in C.
What is the keyword used in combination with a valid c data type to redefine the name of the data type?
The keyword is typedef. typedef int myInteger; myInteger is now an alias for int. This also works for more complex data types, such as arrays and structures. typedef struct { int a; double b; char c; } _myStruct myStruct; _myStruct is now an alias for the structure that contains a, b, and c. I also instantiated one of them, and called it myStruct. You could now repeat this with... _myStruct xyz; ...which would instantiate another one, called xyz. You can reference the members as xyz.a, xyz.b, and xyz.c.
What is the topNet class that everything is derived from in c?
C language: int (but C is NOT a .net language) C# language: object or System.Object
What is typdef in c language?
It is a keyword generally used to rename data types, using typedef you can create alias which can be used to declare the variable. e.g. typedef struct node { int info; struct node *next; }Node; now to declare variable of struct node type we can use the word Node in place of struct node
What is int in 'c' language?
data-type
