C Pointer : Exercise-18 with Solution

Write a program in C to show the usage of pointer to structure.

Pictorial Presentation:

C Exercises: Pictorial: Show the usage of pointer to structure.

Sample Solution:

C Code:

#include <stdio.h>
struct EmpAddress
{
char *ename;
char stname[20];
int pincode;
}
employee={"John Alter","Court Street \n",654134},*pt=&employee;

int main()
{
 	printf("\n\n Pointer : Show the usage of pointer to structure :\n"); 
	printf("--------------------------------------------------------\n");
	printf(" %s from %s \n\n",pt->ename,(*pt).stname);
	return 0;
}

Sample Output:

 Pointer : Show the usage of pointer to structure :                                                           
--------------------------------------------------------

C Programming: Tips of the Day

Static variable inside of a function in C

The scope of variable is where the variable name can be seen. Here, x is visible only inside function foo().

The lifetime of a variable is the period over which it exists. If x were defined without the keyword static, the lifetime would be from the entry into foo() to the return from foo(); so it would be re-initialized to 5 on every call.

The keyword static acts to extend the lifetime of a variable to the lifetime of the programme; e.g. initialization occurs once and once only and then the variable retains its value - whatever it has come to be - over all future calls to foo().
