Question

This is a c programming course (not advanced). I have attempted to do this and failed completely. I can upload my attempt to if it helps, but i dont imagine it can help. Only perhaps to point my mistakes. Which are guaranteed and given. Can anyone help?

Your result for studentDB.c Program should be correct. To test: For the following inputs Alex Taylor "s4567", "Inf", f 23 Oliver "Ford", "s5678", "Eng", 'm', 18 "Daniel Thomas s6789 Inf 'm', 20. The result printed out by your 'main' should be: Alex Taylor, s 4567, Inf, f, 23 Extra: can you alter findoldest to take a length as well as the array, instead of assuming length 6? Extra: can you write a function called pretty to take an item of type student-t and print out the details of that student in a pretty fashion'? Submit your program with submit cp lab7 studentDB.c Stage C Running Club database and functions The starting point for this stage of the lab is the file running.c, which you may download from the course webpage. This file contains a suite of type declarations, as well as the function prototypes for this question (and the code for some helper functions). The first type declaration is a structured type runtime-t to store running results in hours, minutes and seconds. runner-t is another structured type containing the fields name, runid (unique id of the runner, guaranteed to be a positive integer), and two fields pb (personal best) and recent (most recent) of type runtime t. The structured type runclub-t consists of an array of size MAXRUNNERS of type runner-t, together with a field total which we will use to maintain a count of the current number of runners in the running club. Below are details of the structured data types: typedef struct int hr: int min int sec runtime-t typedef struct char name [30]; int runid; runtime-t pb; runtime-t recent t runner t typedef struct t int total runner-t runners DMAXRUNNERSJ run club t

Explanation / Answer

/* Student Data Base*/

#include <stdio.h>

struct studentDB

{

    char firstname[50];

    char lastname[50];

    int rollno;

    char stream[50];     

    char gender[10];     

    int age;

} s[10];

int main()

{

    int i;

    printf("Enter students Data Base: ");

    // storing information

    for(i=0; i<10; ++i)

    {

        s[i].rollno = i+1;

        printf(" For roll number%d, ",s[i].rollno);

        printf("Enter First name: ");

        scanf("%s",s[i].firstname);

        printf("Enter Last name: ");

        scanf("%s",s[i].lastname);

        printf("Enter Stream: ");

        scanf("%s",s[i].stream);

         printf("Enter gender: ");

        scanf("%s",s[i].gender);

        printf("Enter age: ");

        scanf("%d",s[i].age);

        printf(" ");

    }

    printf("Displaying Information: ");

    // displaying information

        for(i=0; i<10; ++i)

    {

        s[i].rollno = i+1;

        printf(" roll number%d, ",s[i].rollno);

        printf("First name: ");

        scanf("%s",s[i].firstname);

        printf("Last name: ");

        scanf("%s",s[i].lastname);

        printf("Stream: ");

        scanf("%s",s[i].stream);

         printf("gender: ");

        scanf("%s",s[i].gender);

        printf("age: ");

        scanf("%d",s[i].age);

        printf(" ");

    }

    return 0;

}
