Q1. What is the form of variable name? A1. 1. Should not begin with digit. 2. Sequence of letters and digits. Q2. What are identifiers? A2. Identifiers = symbols. They can refer to 1. variables 2. type 3. functions 4. labels Q3. What are elements of C language? A3. Following 1. Operator 2. Keywords 3. Identifiers 4. Constants 5. String Literals 6. Punctuation and special characters Q4. What are tokens? A4. The basic element recognized by the compiler is the "token". A token is source-program text that the compiler does not break down into component elements. Note: Elements of C language are discussed above.

L-values and R-values

Expressions in C++ can evaluate to l-values or r-values. L-values are expressions that evaluate to a type other than void and that designate a variable. L-values appear on the left side of an assignment statement (hence the "l" in l-value). Variables that would normally be l-values can be made nonmodifiable by using the const keyword; these cannot appear on the left of an assignment statement. Reference types are always l-values. The term r-value is sometimes used to describe the value of an expression and to distinguish it from an l-value. All l-values are r-values but not all r-values are l-values. // lValues_rValues.cppint main() { int i, j, *p; i = 7; // OK variable name is an l-value. 7 = i; // C2106 constant is an r-value. j * 4 = 7; // C2106 expression j * 4 yields an r-value. *p = i; // OK a dereferenced pointer is an l-value. const int ci = 7; ci = 9; // C3892 ci is a nonmodifiable l-value ((i

Glossary of mobile telephony terms

Dual mode phones They can be used as a GSM or CDMA phone according to your preference. These are essentially 2 phones in one device. OR Mobile phones containing both cellular and non-cellular radios used for voice and data communication purpose. Cellular radio contains GSM/CDMA/W-CDMA and non-cellular contains technology like IEEE 802.11 (Wi-Fi) radio or DECT (Digital Enhanced Cordless Telecommunications) radio. These phones can be used as cellular phones when connected to a wide area cellular network. When within range of a suitable WiFi or DECT network, the phone can be used as a WiFi/DECT phone for all communications purposes. e.g. GSM and WiFi phones using VoIP POTS Plain old telephone service Wi-Fi A Wi-Fi enabled device such as a PC, game console, mobile phone, MP3 Player or PDA can connect to the internet when within range of a wireless network connected to the internet.

Tips to develop C code from scratch.....

I have been blessed to get a chance to really write a from scratch code (before that deciding directory structure and creating blank file also ;)) but simultaneously punished for proceeding directionlessly with the team (even when there was a team leader leader :P). Out of hard things I have learnt following lessons while going for a from scratch development. 1. Decide return codes first. I think all the robust codes are formed due to proper handling of return codes of functions calls. If an enumeration comprising of all the required return codes is finalized before hand then the module writers can effectively use them so that alongwith robustness there is a consistency among the modules. Also to finalize on error codes one has to fully know what he wants to do - the big big key for success. 2. Decide upon coding style Yes, this has to be taken next. If you don't take it now you will never take it later when your code is functional. Even if you take it with lot of resolve (an of co...

Concentration and improving efficiency

Symptom of failure path: 1. Getting tempted for skipping text while reading. 2. Humming song or continuous movement of hand/leg. 3. Watching what others are doing or getting disturbed by passerby. Causes of lack of concentration: 1. Lack of energy required to do that kind of work. 2. Not fully understanding what you are doing. Way out: 1. Constructive interference of desires (use the desire enery as if it takes some cost). 2. Avoid listen-reasponse collision. Don't frame doubts while reading something. Otherwise there will be traffic jam of thoughts. 3. Do not force yourself to memorize something. Take some rest or use yoga methods to gather required energy so that you remember the things the way glue does and not like tying. 4. Best method for learning is learn by doing mistakes. Don't get bogged down by involving too much in gathering prereqisites and mastering them. 5. Appreciate others intelligence with candid heart. Just enjoy the moment and don't involve in any other ...

What is OSD (on screen display) module

The on-screen display unit (OSD) generates the output video signal. It mixes together the information from up to five hardware windows, one of which is a cursor, two YCrCb video data, and the last two are user-defined bitmaps that can be used to display a menu on the screen for example. The OSD windows priority is: (in the order of increasing priority.). - Video window 0 - Video window 1 - Bitmap window 0 - Bitmap window 1 - Cursor window. The priority order is fixed. If overlapping occurs between different windows, the color of each pixel corresponds to the color of the window with the highest priority. Although, transparency and blending factor can be setup for the bitmap windows. The DSC24 main video window supports 2 ping-pong buffers. The address of the buffers is stored in separate registers so that they can be switched easily with a select signal. This feature is particularly useful in video decoding to decode the video data into one buffer and display the data coming from the o...
