Write a Modular C Programming code for Searching Name & Updating Address Data structures (Pointers*)
Read the number of students, read their information, and display the details of the students:
CODE:
#include<stdio.h>
struct person
{
char name[30];
char address[100]
};
struct person b[1000];
struct person *p;
void readStructure(struct person *p ,int n);
void displayStructure(struct person *p ,int n);
void searchperson(struct person *p , int n);
void update(struct person *p , int n);
main()
{
p=&b;
int n;
int k;
printf("Enter the number of Persons: ");
scanf("%d",&n);
readStructure(b,n);
searchperson(b,n);
}
void readStructure(struct person *p ,int n)
{
int i;
for(i=0;i<n;i++) { printf("\nEnter Details of Person %d",i+1); printf("\nEnter the Name:"); scanf("%s",&(p+i)->name);
printf("Enter the Address: ");
scanf("%s",&(p+i)->address);
printf("\n+++++++++++++++++++++++++++++++++++++++++++++++++\n");
}
}
void displayStructure(struct person *p ,int n)
{
printf("\nDetails of person\n");
printf("\nName: %s",(p+n)->name);
printf("\nAddress: %s",(p+n)->address);
printf("\n+++++++++++++++++++++++++++++++++++++++++++++++++\n");
}
void searchperson(struct person *p , int n)
{
int i,j,x;
char k[30];
int flag=1;
printf("\nEnter the persons Name to search:");
scanf("%s",&k);
for(i=0;i<n;i++)
{
if((strcmp(k,(p+i)->name)) == 0)
{
printf("\nPerson found!!!\n");
printf("\nName= %s\nAddress= %s\n",(p+i)->name,(p+i)->address);
flag=1;
x=i;
update(b,x);
break;
}
else
flag=0;
}
if(flag==0)
{
printf("\nPerson not found!!!");
printf("\n-----------------------------------------------------------------------------------------------------------\n");
}
}
void update(struct person *p , int n)
{
printf("Enter Updated address: ");
scanf("%s",&(p+n)->address);
printf("\n+++++++++++++++++++++++++++++++++++++++++++++++++\n");
printf("\nUpdated address: ");
displayStructure(b,n);
}
OUTPUT
Enter the number of Persons: 3 Enter Details of Person 1 Enter the Name:Rocky Enter the Address: Mumbai +++++++++++++++++++++++++++++++++++++++++++++++++ Enter Details of Person 2 Enter the Name:Adheera Enter the Address: SouthIndia +++++++++++++++++++++++++++++++++++++++++++++++++ Enter Details of Person 3 Enter the Name:Inayath Enter the Address: Dubai +++++++++++++++++++++++++++++++++++++++++++++++++ Enter the persons Name to search:Rocky Person found!!! Name= Rocky Address= Mumbai Enter Updated address: KGF +++++++++++++++++++++++++++++++++++++++++++++++++ Updated address: Details of person Name: Rocky Address: KGF +++++++++++++++++++++++++++++++++++++++++++++++++ Process returned 0 (0x0) execution time : 206.041 s Press any key to continue.
