Help us in Interfacing of EEPROM ,RTC, 4-BIT lcd with Microcontroller, plz provide us codes too........:roll::roll::roll:
Typically in the C language character strings are terminated with a NULL (\0) which has a byte value of 0x00. The pointer to type char s, which is initialized to the first character of the character string, is first dereferenced using the * operator, then checked by the while loop to ensure it is not the
