Data Structures/Records

Question

My current program looks like this. This program should ask 5 records of a person and display them.

#include<stdio.h>

struct rec {
    char name[100],address[100];
    double age,mobileno;
}x;

main()
{
    int i;
    clrscr();

    for(i=1;i<=5;i++)
    {
        printf("Enter Your Name: ");
        scanf("%s",&x.name);

        printf("Enter Your Age: ");
        scanf("%lf",&x.age);

        printf("Enter Your Address: ");
        scanf("%s",&x.address);

        printf("Enter Your Mobile No.: ");
        scanf("%lf",&x.mobileno);

    }

    printf("\n\nThe Information has been added");
    printf("\n\nNAME        AGE     ADDRESS     MOBILE NUMBER");

    for(i=1;i<=5;i++)
    {
        printf("\n%s        %.0lf       %s      %.0lf",x.name,x.age,x.address,x.mobileno);
    }
    getch();
}

I have a problem in displaying the 5 different record. How do I display the five records in one printf?

Answer 1

You simply need a collection of structures to save the data into, currently you're just overwriting the data each time. There are a lot of ways to do this, but you could do something like use a static array, for example:

struct rec {
    char name[100],address[100];
    double age,mobileno;
};

int main() {
    struct rec records[5];

    for(i=0;i<5;i++)        // <-- note this is 0 to 4, not 1 to 5
    {
        printf("Enter Your Name: ");
        scanf("%s",records[i].name);  // <-- don't add the & for the string input

Same for the printf() further down:

for(i=0; i<5; i++)
{
    printf("Name is: %s\n", records[i].name);
