    Token Problem

    I have created a function that reads characters from the keyboard into a buffer. It terminates on reading a return or on recieving 128 characters.

    I now want to create a function that will take a token from this buffer and place it in another array.
    if i got:
    test test2
    I would want test holding in the array, with the space being the separator.

    Ne suggestions would be very welcome, code is show below.

    #include <stdio.h>
    #include <string.h>
    	int i;
    	char inbuff[128];
    	FILE *fp;
    	void query();
    	char *gettoken(char sep);
    	char inbuff[128];
    return 0;
    /*Reads characters from input stream into a buffer*/
    void query()
    { 	char c;
    	while ( (i<128) && (c!='\n') )
    printf( "Currently in the buffer: %s\n", inbuff );

    - don't use global variables unless you really need to. I see no reason to in your program.

    - Your input loop could fill all 128 bytes of the array, meaning the \0 byte will be written to position 129, which is outside the array bounds.

    - char c; The variable should be declared as an int to allow you to trap EOF.

    - Read up about fgets() and reading input

    Once you've done the reading, loop through the array, copying the bits you want to another array.
    When all else fails, read the instructions.
    If you're posting code, use code tags: [code] /* insert code here */ [/code]
