Question

how do i create a function to update the contents of the student record. The only field that should not be able to be updated is the student ID. Create a prompt for the user to enter the student ID number to search for. Create a prompt to determine which field the user wished to update then accept new input for that field and change the contents of the appropriate student. with the structure struct Node { void *nodeData; int nodeLink; }; typedef struct Student { int stuID; char stuName[61]; char stuMajor[5]; double stuGPA;

Explanation / Answer

#include <stdio.h>
#include <stdlib.h>
#include <string.h>

void main(void)
{
    FILE *fp;
struct Node List[15];
int Begin, current, newStuff, oldStuff;
double oldData;
int(*fnPtr)();

Begin = 0;

struct Student *stu;

for (int x = 0; x < 3; x++)
{
    newStuff = FindSpace(List);

    List[newStuff].nodeData = readData(stdin);

    addNode(Begin, List, newStuff);
}

for (int i = Begin; i != -1; i = List[i].nodeLink)
    fprintf(stdout,"%.2f ",((Stu*)List[i].nodeData));

for (int i = Begin; i != -1; i = List[i].nodeLink)
    free(List[i].nodeData);
}

void updateNode(struct Node List[], int current, int *NewData)
{

        int temp1;

    List[current].nodeLink = List[*NewData].nodeData;
    List[*NewData].nodeLink = NewData;

    printf("enter the student ID number ");

}
