Thread: help with structures

I am working on a project using structures and when I compile it says " error: request for member `fName' in something not a structure or union" and it says the same thing for the different elements that I am trying to access. My code so far is:

Code:

#include <stdio.h>
#include <stdbool.h>
#define SIZE 30
   
 typedef  struct   //student records
{
   char fName[20];
   char lName[20];
   int gLevel;
   char ssn[11];
   int month;
   int day;
   int year;
}STUDENT;

void fillStruct(char** argv,STUDENT* sarr[],int num);
void getFile(char** argv,STUDENT* sarr[]);
void sortFile(STUDENT* sarr[]);
void srchSort(STUDENT* pstud[],int argc);
void prntFile(STUDENT* sarr[],int num);
void swap(int *num1, int *num2);
void search(int arr[]);
int  binSrch(int arr[], int item, int lb, int ub);
         
int main(int argc,char *argv[])
{
   STUDENT* stud[SIZE];
   int num;
   if(argc==3)
     { fillStruct(argv,stud,num);
       prntFile(stud, num);
     }
      
         
  return 0;
}

void prntFile(STUDENT* sarr[],int num)
{
   int i;
   char name[40];
   char bday[11];
         
     printf("\n%30s%7s%15s%13s","Name","Level","SSN","Birthdate");
     printf("\n%30s%7s%15s%13s","----","-----","---","---------");
     for(i=0;i<num;i++)
     {
         strcpy(name,sarr[i].fName); //put name on a sinle line
         strcat(name," ");
         strcat(name,sarr[i].lName);
 
         strcpy(bday,sarr[i].month); //put birthday on a single line
         strcat(bday,"/");
         strcat(bday,sarr[i].day);
         strcat(bday,"/");
         strcat(bday,sarr[i].year);
 
         printf("\n%30s%7d%15s%13s",name,sarr[i].level,sarr[i].ssn,bday);
     }
     printf("\n\n");
   
   
}

If anyone could please tell me what I am doing wrong I would greatly appreciate it.

I was able to get rid of that error by having a different function call it after filling it, but now that has caused a different problem. the code I changed is:

Code:

int main(int argc,char *argv[])
{
   STUDENT* stud[SIZE];
   int num;
   if(argc==3)
     { fillStruct(argv,stud,num);

     }
    
    
  return 0;
}  
void fillStruct(char** argv,STUDENT* sarr[],int num)
{  int i;
         
 num=atoi(argv[1]);
 if(num<SIZE)
   {for(i=0; i<num; i++)
      {
        getFile(argv, &sarr[i]);
        prntFile(sarr[i]);
       }
   }
         
 
}

void prntFile(STUDENT stud) 
{
   int i;
   char name[40];
   char bday[11];
         
     printf("\n&#37;30s%7s%15s%13s","Name","Level","SSN","Birthdate");
     printf("\n%30s%7s%15s%13s","----","-----","---","---------");
   
             
         strcpy(name,stud.fName); //put name on a sinle line
         strcat(name," ");
         strcat(name,stud.lName);
    
         strcpy(bday,stud.month); //put birthday on a single line
         strcat(bday,"/");
         strcat(bday,stud.day);
         strcat(bday,"/");
         strcat(bday,stud.year);
 
         printf("\n%30s%7d%15s%13s",name,stud.level,stud.ssn,bday);
 
     printf("\n\n");
   
   
}

now the error that is coming up is "In function `fillStruct':
proj5a.c:45: error: incompatible type for argument 1 of `prntFile'"
and " In function `prntFile':
proj5a.c:88: warning: passing arg 2 of `strcpy' makes pointer from integer without a cast"

sarr[i] is still a STUDENT *, not a STUDENT.

ok, i thought I understood what you were saying but I don't know how to fix it, with out causing more errors.
