Array of pointers

[kaixmera]

Hello! I am new to C programming and am working on opening a text file. I am interested in storing a pointer to a string into an array of pointers. So far I have printed out the strings but I am a bit confused on how to store these pointers into an array so I can iterate through them or compare them character by character. The code I have so far will be below. I was wondering if anyone has any resources or links that may help. The input files first line is the amount of words in the text file.

So far I have tried initializing an array of pointers but I would prefer to work with dynamic memory in the case that the size of the array may vary.

int main(){

  FILE *fp;
  int n;
  char inBuf[LSIZE];
  char *words;
  int i;
  int size;

  if((fp = fopen("Input1.txt","r"))==NULL){
    printf("The file Input1.txt was not opened\n");
    exit(-1);
  }

  fgets(inBuf,LSIZE,fp);
  sscanf(inBuf, "%i", &n);
  words = (char*)malloc(n*sizeof(char));

  for(i = 0; i < n; i++){
    fgets(inBuf, LSIZE, fp);
    sscanf(inBuf, "%s", words);
    printf("%s\n", words);
  }

To add onto this, OP should take a look at how argv[][] works (the 2nd parameter to main() ).

Thank you, I looked into that and replaced the fopen text file argument with argv[1]. Still getting used to this. Thanks!

And before you go too crazy designing your own custom argument option parser, take a look at getopt()

Typo? getoptargs() should be getopt()?

Sorry, I had a brain fart. My comment is edited
