    Post write value from char * to char[] ?

    hi, i have this:

    BOOL function(const char *Text)
        // func
    but i need to cut text from one character occurance to the end like this:
                    char txt[32];
    		if ((ptr = strstr(txt, ":")) != 0)
    			*ptr = '\0';
    so i wanted to make txt = Text and do operations above but i can't =\

    would appreciate any help ^^

    First you need to use strcpy() to copy from text to txt
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.

    You can't assign directly to an array. For strings (char), you need to use strcpy. For other things, it's usually memcpy. Or in C++, we tend to use C++ constructs such as std::vector which allows us to copy stuff merely be assigning one object to another.

    Outside of your DOS world, your header file is meaningless.
