What is the difference between Typedef and Reference in C plus plus?
A typedef is a compiler macro. A reference is a pointer, usually implemented with transparent syntax. They have no relationship between each other.
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 is the use of loader in c language?
There is no part called 'loader' in C language.
What computer language java or C plus plus should you use to design an app for the ipod or should i use a software?

What are the different reserve words in c-language?
Reserve words, also known as keywords are words whose meaning are already defined by a compiler. C language has a total of 32 reserve words. Short, union, else, for, goto, unsigned, enum, extern, char, continue, switch, struct, typedef are some examples.
How is typedef different from int in c language?
They are entirely different things; int is a type, typedef is a way to define types.
What is the use of type def in c?
A typedef is used to define a type. The clue is in the name: typedef = type definition.
User defined data type in c plus plus?
Use "typedef" : both in C and C++.
Typedef int a a a Is this possible in C?
No, but 'typedef int a;' is possible, it defines the type 'a'.
How many types in header file in mathh header file in c language?
Look for typedef in it, but I don't think you will find any.
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
Why you are use to c language?
I do use am a programmer, because C-language.
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.
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... };
What are the modofier in turbo C?
You can use every standard C modifier in TurboC: long, short, signed, unsigned; and every storage class as well: static, extern, auto, register, typedef.
