Thread: Bus error

Hello to all,

Unable to locate the source of my error. Any help would be great. Here is the code:

Code:

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

    
int main()
    {
        char input[1000] ;        
        char *firstWord, *command ;
        
        for(;;)
            {
                printf("SeqTool> ") ;
                fgets(input, 1000, stdin) ;
                        
                firstWord = strtok( input, " \t" ) ;
                command = strtok( NULL, " \t" ) ;    
                
                // Load sequence in FASTA format
                if(strcmp ( command, "read" ))
                    {
                        printf("Not available");
                    }
                    
                // Write sequence in FASTA format
                else if (strcmp ( command, "write"))
                    {
                        printf("Not available");
                    }
                    
                // Display a detailed report for a selected sequence
                else if (strcmp ( command, "show"))
                    {
                        printf("Not available");
                    }
                    
                // Display a summary list of loaded sequences
                else if (strcmp ( command, "list"))
                    {
                        printf("Not available");
                    }
                    
                // Align two nucleotide sequences
                else if (strcmp (command, "align"))
                    {
                        printf("Not available");
                    }
                
                // Quit
                else if (strcmp (command, "quit"))
                    {
                        printf("Not available");
                    }
                
                // Any other command
                else
                    {
                        printf("Improper command");
                    }
                
                continue ;
            }
    
    return(0) ;
    }

How can I set a test for certain keywords using strcmp?

Thanks for the link. However, I am still receiving a bus error though.

What do you mean. Sorry, I am a newbie.

Maybe it will help if I tell you what I am trying to do. I want the program to act like a command line interface. I am trying to use strtok to take the first word of the command so that I can jump to the code that is activated by that keyword. for instance:

Seqtool> read <filename>

I want to capture the token "read" and the start performing the if loop for that command.

Sorry if I am confusing.

thanks.
