Thread: any suggestion - pointer, strtok, function etc

Hi to all,

I have done the following code:

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

void decodeMorse(char *tokenPointer, char *plainText){

if((strcmp(tokenPointer,".-"))==0)
plainText="A";

if((strcmp(tokenPointer,"-..."))==0)
plainText="B";
}

void main(){
char inputStr[256];
char outputStr[256];
char *tokenPointer;
char *token=NULL;
int c;
int i=0;

while((c=getchar())!=EOF)
inputStr[i++]=c;
inputStr[i]='\0';

tokenPointer=strtok(inputStr," ");

/* we may have to include the following statements here too :
decodeMorse(tokenPointer,token);
strcat(outputStr, token); */ /* not really sure ****/

/*any suggestion??? ****/

while(tokenPointer != NULL){
strcat(outputStr, " ");
decodeMorse(tokenPointer,token);
strcat(outputStr, token);

tokenPointer=strtok(NULL, " ");

}
printf("%s\n",outputStr);
getchar();
}


In my system, I can compile this, but when I run it results exception.

Any pointers would be highly appreciated.

Code:

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

char *decodeMorse ( char *tokenPointer ) {
    char *result = "?";     // some unknown morse sequence...
    if((strcmp( tokenPointer,".-" ))==0)
        result = "A";
    if((strcmp( tokenPointer,"-..." ))==0)
        result = "B";
    return result;
}

int main () {           // never void
    char inputStr[256];
    char outputStr[256];
    char *morse;
    char *ascii;
    char *seps = " \n"; // spaces and newlines are separators

    /* read a whole line of morse */
    fgets( inputStr, sizeof(inputStr), stdin );

    outputStr[0] = '\0';    // empty the string

    /* split the line at each space */
    for ( morse = strtok(inputStr,seps) ;
          morse != NULL ;
          morse = strtok(NULL,seps) ) {
        ascii = decodeMorse( morse );
        strcat( outputStr, " " );
        strcat( outputStr, ascii );
    }
    printf( "%s\n",outputStr );

    getchar( );
    return 0;   // all successful programs return 0
}
