Function to Center Align Text in C++ Program

Posted on August 1, 2010 by Suresh Khanal

Though it is sim­ple and really intu­itive to align text in cen­ter of screen through C++ pro­gram, I found many new stu­dents are con­fused and keep look­ing for any built in func­tion. Thus, here I present the source code of func­tion that will cen­ter the text sup­plied in cen­ter of screen (horizontally).

func­tion centerText(char* s){

len=strlen(s);

int pos=(int)((80-len)/2);

for (int i=0; i<pos; i++)

   cout« “ ”;

cout«s;

}

C++ Tutorial and Online Ebook

Posted on June 30, 2010 by Suresh Khanal

There are flood of tuto­ri­als on C++ and Exam­ple source codes as well as sam­ple codes and videos. Today I’m refer­ring to a web­site ded­i­cated to C++ learn­ing – LearnCpp.com, ‘Tuto­ri­als to help you mas­ter C++ and object-oriented programming’.

This web­site is a com­plete online book as well. The site is divided into 18 chap­ters and an Appen­dix. The dif­fer­ence lies between an eBook and this site is that you can inter­act here but not in an eBook.

Source Code of Stack Data Structure

Down­load Stack Class Source Code stack.cpp

The day before, we talked about stack data struc­ture in http://data-structures-and-algorithms.psexam.com/stacks-data-structure/ regard­ing ‘What is data struc­ture?’, Stack Oper­a­tion, Uses of Stacks and Stack Rep­re­sen­ta­tion. We talked a lot on the­ory. The expla­na­tion is never com­plete with­out an exam­ple. Here is the code for a C++ class of stack data structure.

Fol­low­ing is the source code for stack class and a main func­tion to test if the class works well.

100 C/C++ Exam Questions

Posted on June 10, 2010 by Suresh Khanal

I have pre­sented fol­low­ing 100 ques­tions that were asked in dif­fer­ent exams from C/C++ chap­ter. It would take long to fin­ish answer­ing all these ques­tions and then pub­lish.  So, I pre­sented the ques­tions first and will go dig­ging for answers in com­ing posts, prob­a­bly. I’m plan­ning to cre­ate a small ebook of C++ Short Ques­tions and Answers. Will you help me by answer­ing these questions?

  1. What is vir­tual constructors/destructors?
  2. What is the dif­fer­ence between an object and a class?
  3. Why can’t we over­load the sizeof, :? , :: .,

Introduction to C/C++ Questions And Answers

Posted on June 7, 2010 by Suresh Khanal

Q.1. Who invented C pro­gram­ming lan­guage and when?

C pro­gram­ming lan­guage was invented by Den­nis Richie at Bell Tele­phone Lab­o­ra­to­ries in 1972.

Q.2. What were the pri­mary goals to develop C pro­gram­ming language?

C pro­gram­ming lan­guage was devel­oped pri­mar­ily as a sys­tem lan­guage, i.e. a lan­guage to write oper­at­ing sys­tems. The pri­mary goals were to:

  • pro­duce a min­i­mal­is­tic lan­guage that was easy to compile
  • allowed effi­cient access to memory
  • pro­duce efficient code
  • did not need exten­sive run-time support

Despite being a fairly low-level high level lan­guge, it was designed to encour­age machine and plat­form inde­pen­dent programming.

Q.3. Jus­tify “C and Unix…
