Thread: Basic C programming help needed

You need to get the size of your array of structs, BEFORE you create the array.

For now, perhaps just use a number like 5 or 10?

If you put comments in your code, please keep the line length short. The font used for code is quite wide, and long lines "break" the forum tables, and make your posts hard to read.

Better to put long comments on code, outside the code tags.

well would any of you mind giving me a simple array of structures with directly inputted values and then prints them out?

I still can't understand it from your posts but if i just saw an example (i dont need/want it to be with the info my program is using just a simple array of structures so i can see how it works and looks)

Any help?

Code:

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

struct Info{                //global definition of struct Info
  char name[81];  
  int phone;    
  char street[81];
  char email[81];
};                          //no Info struct exists yet


void print(struct Info info){
  printf("Name: %s\n", info.name);
  printf("Phone Number: %d\n", info.phone);
  printf("Street address: %s\n", info.street);
  printf("E-mail: %s\n", info.email);
}


int main(void){
	
  int i;
  /* declare an instance of the Info struct and assign some values */
  struct Info info = {"Buzz Lightyear", 12345, "999 Infinity Way", "[email protected]" };
  struct Info *pinfo = &info;         //declare a pointer to struct
                                      //and assign it the address of info
  printf("\n\n\n\n\n");
	print(info);	                      //print via struct members

  printf("\n\n");                     //print via pointer to struct members
  printf("Name: %s\n", pinfo->name);
  printf("Phone Number: %d\n", pinfo->phone);
  printf("Street address: %s\n", pinfo->street);
  printf("E-mail: %s\n", pinfo->email);
	 
  printf("\n\n\t\t\t    press enter when ready");
  i=getchar(); ++i;
  return 0;
}

yes Adak that definitely helps.
