Write a program that reads different names and addresses into the computer and rearrange them into alphabetical order using the structure variables.

#include<stdio.h>

#include<conio.h>

#include<string.h>

struct student

{

char name[30];

char add [30];

}std[100];

void main()

{

char tname[30],tadd[30];

int i,j,n;

printf("\n Enter how many students: ");

scanf("%d",&n);

printf("Enter names and addresses for %d srudents: ",n);

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

scanf("%s%s",std[i].name, std[i].add);

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

for(j=i+1;j<n;j++)
