my c code is as shown below but when i compile in keil compailer it will show as c(4): warning C318: can't open file 'DELAY.H' c(21): warning C206: 'delay_ms': missing function-prototype (21): error C267: 'delay_ms': requires ANSI-style prototype Target not created please someone help me to correct this
