Declaring an array of character pointers (arg passing)
- by Isaac Copper
This is something that should be easy to answer, but is more difficult for me to find a particular right answer on Google or in K&R. I could totally be overlooking this, too, and if so please set me straight!
The pertinent code is below:
int main(){
char tokens[100][100];
char str = "This is my string";
tokenize(str, tokens);
for(int i = 0; i < 100; i++){
printf("%s is a token\n", token[i]);
}
}
void tokenize(char *str, char tokens[][]){
//do stuff with string and tokens, putting
//chars into the token array like so:
tokens[i][j] = <A CHAR>
}
So I realize that I can't have char tokens[][] in my tokenize function, but if I put in char **tokens instead, I get a compiler warning. Also, when I try to put a char into my char array with tokens[i][j] = <A CHAR>, I segfault.
Where am I going wrong? (And in how many ways... and how can I fix it?)
Thanks so much!
