strcmp question

Part of my file:

Code:

---

int main(void)
{

  int done = 0;
  char line[300];

  do
  {
      printf("> ");
      fgets(line, 300, stdin);
      line[strlen(line) - 1] = '\0';

      if(strcmp(line, "area items") == 0)
      {
        areaItems(current, startPtr);
      }

      if(strcmp(line, "commands") == 0)
      {
        commands();
      }

//...etc

  }while(! done);

  return(0);
}

The code is working fine. However, I'd like the user to be able to type "grab butter" or "grab toast" or "grab [item]". Can I still use strcmp to read in grab but store the second word in a char name[10]? Or is there something much better to use than strcmp?

Hope that makes sense. Thanks

You can use strtok to parse any command the user enters into a series of tokens. Then you can use strcmp on the first token to see if it's "grab", and then do whatever you want with the remaining tokens.

sscanf will do what you want.


Quzah.

As quzah suggested, you would want an fgets / sscanf pair; which is the easiest way, IMO, to get user input. So something like this:

Code:

---

#include <stdio.h>

int main(void){

        char inputBuffer[100]={0};
        char word1[10]={0}, word2[10]={0};

        printf("> ");
        //grab entire lineof input
        fgets(inputBuffer, sizeof(inputBuffer), stdin);
       
        //Parse the line into, in this case 2 different strings seperated by spaces
        //it could be any format you want, e.g. %s %d %s %c, ect.
        sscanf(inputBuffer, "%s %s", word1, word2);
       
        printf("Word1:%s Word2:%s ", word1, word2);
       
        getchar();
        return (0);
}

Thanks! Got sscanf to work

If you only care if the words are present... but arent worried about the order... you could use strstr() which might be faster...
