 C program to study  typedef  keyword

typedef is a keyword used in C language to assign alternative names to existing types. Its mostly used with user-defined data types, when names of data types get slightly complicated. Following is the general syntax for using typedef

typedef unsigned char BYTE;

typedef can be used to give a name to user defined data type as well. Let's see its use with structures.

typedef struct
{
  type member1;
  type member2;
  type member3;
} type_name ;

Here is a sample C code that explains how to apply user-defined datatype. Output for the program is also shown below.

#include <stdio.h>
#include <conio.h>
void main()
{
typedef int newtypename;
newtypename x,y,z;
x=50;
y=20;
z=x+y;
printf(“Sum=%d”,z);
getch();
}

OUTPUT
