Operators in C | typedef

typedef statement

typedef statement helps us to give/assign a new name to an existing datatype. Further the new name can be used to declare variables.

Syntax:
typedef datatype newname;

Example:

typedef int hello;
int a,b; hello a,b;

typedef float real;
float x,y; real x,y;

typedef char hello;
char name[20]; hello name[20];

typedef char hello[20];
char name[20]; hello name;

/* 
typedef
*/
#include<stdio.h>
int main()
{
     typedef int hello;
     hello a,b,c;
     printf("Enter any no ");
     scanf("%d",&a);
     b=a*a;
     c=a*a*a;
     printf("Square = %d\n",b);
     printf("Cube = %d\n",c);
     return(0);
}

/* Output */
Enter any no 5
Square = 25
Cube = 125
