Thread: Command Line Arguements

what am I doing wrong here? Can somebody help me figure it out? I'm grateful for everything I've been shown thus far, I wish I would have known about this site sooner.

Code:

void openFile(char *pFPIn, int argc, char strArray[][MAXLEN])
{
 int i;
 
 if (argc !=  3) 
   printf("\nNot enough Command Line arguments.");      
  else if (argv[2] < 1 || argv[2]  > 15)
   printf("\nNumber %d is not between 1 and 15.", argv[1]);
 
 if((*pFPIN = fopen(argv[2], "r")) !=NULL)
  {
    for (i = 0; i < argv[2]; i++)
    fscanf(*pFPIN, "%s", strArray[i]); 
   
  }
  
 
}

fscanf(*pFPIN, "%s", &strArray[i]);
You've dereferenced a pointer to the file. So you end up passing the wrong thing to fscanf: just send it the pointer.
Also notice my addition of the address-of operator.

Code:

if (argc !=  3) 
   printf("\nNot enough Command Line arguments.");      
else if (argv[2] < 1 || argv[2]  > 15)
   printf("\nNumber %d is not between 1 and 15.", argv[1]);

Do this stuff in main() especially because you didn't pass the argv[] array to openFile()

Code:

#include <stdio.h> 
#include <ctype.h>
#include <string.h>
 
 
#define MAXWORD 15
#define MAXLEN 20

 

void printName (void);
void sort(char strArray[][MAXLEN], int currentsize);
int binSrch(char strArray[][MAXLEN], char *item,
            int lowerbound, int upperbound);
void printArray(char strArray[][MAXLEN], int currentsize);
void openFile(char *pFPIN, char strArray[][MAXLEN]);
int srch(char srtArray[][MAXLEN], int *item);
int getValue(void);
 

int main (int argc, char *argv[])
{
 char strArray[MAXWORD][MAXLEN];
 int item, result;
 int currentsize;

 printName(void);   
 
  if (argv[2] !=  3)
   printf("\nNot enough Command Line arguments.");
  else if (argv[2] < 1 || argv[2]  > 15)
   printf("\nNumber %d is not between 1 and 15.", argv[1]);

 openFile(argv[2], *strArray);

 return 0;
}





void openFile(char *pFPIN, char strArray[][MAXLEN])
{
 if((*pFPIN = fopen(argv[2], "r")) !=NULL)
  {
    for (i = 0; i < argv[2]; i++)
    fscanf(*pFPIN, "%s", &strArray[i]);
 
  }
   
  
}

What else do I need to add/modify to get this thing to work (just read in the strings), I'm still confused as to how to make all of this work... Everytime I think I get the hang of it, it throws me for another loop.
The code above is just the function definition for the openFile code, as well as the main( ) code.
What else needs to be done?
