C-Programming

We can use the pointer as an array. To access the member variable of this type of the variable we can follow syntax of this example:

Program to store and display the name and age of n students using the concept of both structure and pointer.

#include<stdio.h>

#include<conio.h>

void main()

{

struct student

{

char name[20];

int age;

};

struct student *std;

int n,i;

clrscr();

printf(“\nplease entere the number of students:\t”);

scanf(“%d”,&n);

for(i=0;i<n;i++)

     {

printf(“\nplease enter the name of the %dth student:\t”,i+1);

scanf(“%s”,(std+i)->name);

printf(“\nplease enter the age:\t”);

scanf(“%d”,&(std+i)->age);

}

//to display

printf(“\n\n\n\nS. no.\tName\t\tAge”);

for(i=0;i<n;i++)

printf(“%d.\t%s\t%d”,i+1,*((std+i)->name), *((std+i)->age));

getch();

}
