I have been working with java from a long time, I have never worked with C programming language...I am from electronics background so was not in touch with these languages...I have started learning C language these days...and I have found it awesome...atleast I will get something to write as a code...not like java where every thing is provided in packages...I have one question I am searching for the usage of ungetch function, I have found definition everywhere but I couldn't found an example which can explain the usage. Kindly help me on this. I hope to get a positive reply from you guys and also kindly let me know a good ID for C. Thanks!!
