C++
Dev-C is a full-featured C and C Integrated Development Environment (IDE) for Windows platforms. Millions of developers, students and researchers use Dev-C since the first version was released in 1998. It has been featured in dozens of C and scientific books and remains one of the favorite learning tool among universities & schools. I'm trying to use the outportb function to send a signal to a RS-232 serial port. I understand that in order to use the function I need to #include. I am using Dev-C as my compiler and am having no luck when compiling the code. I am told that the function is undefined. At the time of this writing (C17) and to my knowledge, C doesn’t offer such a feature. A library called timercpp, that replicates in C this handy functionality of other languages, was on the front page of HN. It has a nice interface that allows for expressive code, however I don’t think it is quite ready for being used in production. The header file graphics.h contains putpixel function which plots a pixel at location (x, y) of specified color. Syntax: void putpixel(int x, int y, int color); where, (x, y) is the location at which pixel is to be put, and color specifies the color of the pixel. In today’s C programming language tutorial we take a look at how to use time and date from C programs. To make use of time and date function you need to include the time.h header file from the standard C library. This header file contains functions and macros that provide standardized access to time and date.
