separating line of arrays into array of arrays

If anyone can help -much appreciate

I want to take a line of input from the user using an array of cmd[100]; then take that input and separating them out with spaces as a delimiter into an array of arrays cmdarg[][].

I think the code below does separate them out, but for some reason i can't cout anything other than cmdarg[0]. Nothing else comes out???

this will be use as a command line with arguments in a program, but i am having a tough time separating the commands and arguments into its own vector of arrays. Is better to do it with strings??? I am not sure of what to use?

thanks in advance





//partial codes
char *c[1000];
char cmd[100];
char cmdarg[1000][1000];
int status,i=0,j=0,k=0;


cin.ignore();

cout<<"Commands:";
cin.getline(cmd,100);

for(i=0;i<100;i++){
if(cmd[i]==' '){//space
j++; //increase row
k==-1;//reset column
}
if(cmd[i]!=' '){//put in next column
cmdarg[j][k]=cmd[i];//insert in array of arrays
}
k++;//increase column
}

is this a typo ?

k==-1;//reset column

k=-1 is not a column, because once the space is found, it has to go thru the loop which will increase (k++) to zero again.

thanks

Code:

---

int main ( ) {
    char cmd[100] = "this is a test";
    char cmd_words[20][100];
    int  i,nwords=0,nword_chars=0;
    for ( i = 0 ; i < strlen(cmd) ; i++ ) {
        if ( cmd[i] != ' ' ) {
            // copy the char, and keep the word a proper string (the \0)
            cmd_words[nwords][nword_chars++] = cmd[i];
            cmd_words[nwords][nword_chars] = '\0';
        } else {
            nword_chars = 0;  // start of...
            nwords++;  // the next word
        }
    }
    // trap last word not ending in a space
    if ( nword_chars != 0 ) nwords++;

    for ( i = 0 ; i < nwords ; i++ ) {
        printf( "Word %d is %s\n", i, cmd_words[i] );
    }
    return 0;
}

Bear in mind that this is almost 1MB in size - you don't want too many of these lying around.
