C Program to use typedef in pointer

The typedef may be used in declaration of a number of pointers of the same type. It does not change the type, it only creates a synonym, i.e., another name for the same type as illustrated below.

typedef float* FP; // Now FP represents float*

float x,y,z;

FP px =&x, py = &y, pz = &z ; // Use of FP

In the above code px, py, and pz are pointers initialized with addresses of x, y, and z respectively.

Illustrates use of typedef in pointer declaration.

#include <stdio.h> 
 void main() 
 { 
    typedef double* Dp; 
    double x = 10.5,y = 8.6, z = 12.5; 
    Dp px = &x , py = &y, pz = &z; 
    clrscr(); 
    printf("x = %.3lf,\t *px =  %.3lf\t px = %p \n", x, *px, px); 
    printf("y = %.3lf,\t *py =  %.3lf\t py = %p \n", y, *py, py); 
    printf("z = %.3lf,\t *pz =  %.3lf\t pz = %p \n", z, *pz, pz); 
 }   

The expected output is as given below.
