I am working on a little hobby project, it reads user input and then stores it in a pointer to char array. The problem is that the output is not correct. So i dont know if it is the output, or the storing that is wrong. I am used to using C++, but always used vector <string> in c++ to create my list. Here is my code:
#include <stdio.h>
#include <string.h>
#include <stdlib.h>
#include <stdbool.h>
#define MAX_BUFFER_SIZE 512
int main(int argc, char *argv[])
{
char input[MAX_BUFFER_SIZE];
char *commands[20];
char *token;
int counter;
bool _continue = true;
while(_continue)
{
counter = 0;
// Read user input.
printf(">");
fgets(input, MAX_BUFFER_SIZE, stdin);
// Split string.
token = strtok(input, " ");
while(token != NULL)
{
token = strtok(NULL, " ");
if(counter > 20)
{
printf("\n<x>To many commands.\n");
break;
}
else
{
commands[counter] = token;
}
counter++;
}
for(int i = 0; i < counter; i++)
printf("%s\n", commands[i]);
}
return 0;
}
It gives this output when I enter h h:
h
(null)
I know that the (null) is a trailing character that i can just remove, but where is my second h?
