Question

Need help with copying array object to a temp array object using a for loop (see code + comments below)….. Thanks in advance!!!!

    int counter;
    char buffer[] = "this is what i want 0 ignore the rest after the zero"; //
    char command[sizeof(buffer)];

    for ( counter = 0; counter < sizeof(buffer); counter++ ){
        if ( buffer[counter] == '0' ){      
            break; // Exit loop (Should Exit)
        }
        command[counter] = buffer[counter]; // Copy array object into new array
        printf("%c",command[counter]);
    }
    printf("\n",NULL);
    printf("%s\n",command); // However when I print it contains the whole array this shouldnt be is should only contain "this is what i want "

Your code is working fine:

output:
this is what i want
this is what i want

Edit: That being said, you need to initialize your output buffer:

char command[sizeof(buffer)]={}; // now the string will be null-termiated
                                 // no matter where the copy ends
