Simple Problems in C++ Part III

Yesterday I was having a look at my traffic statistics when I came to know about one thing. I saw that most of the visitors to this blog paying attention to the two of my recent articles Simple Problems in C++ Part I and Simple Problems in C++ part II.

Seeing that, I made up my mind to write the third part of the Problems in C++ series with some more interesting problems. Now, without wasting your time anymore, I present you with some more Simple problems in C++. Here they are :-

Problem No. 1:

#include<iostream.h>

   void main(void)
   {
   int i=1;

   for(;;)
     {
     cout<<i++;
     if (i>10) break;
     }
   }

QUESTION: Is there any error in the program?

Problem No. 2:

   #include<iostream.h>

   void main(void)
   {
   int i=1;

   while()
     {
     cout<<i++;
     if (i>10) break;
     }
   }

QUESTION: Is there any error in the program?

Problem No. 3:

   #include<iostream.h>

   void main(void)
   {
   int a=10,b=20;

   if(!(!a) && a)
     cout<<"a="<<a;
   else
     cout<<"b="<<b;
   }

QUESTION: What will be the output of this program?

Problem No. 4

   #include<iostream.h>

   void main(void)
   {
   int a=10;

   if(a>5);
   if(a=10) cout<<"YES";
   else;
   cout<<"NO";
   }

QUESTION: What will be the output of this program?

Problem No. 5:

   #include<iostream.h>

   void main(void)
   {
   unsigned short int i=65536;

   while(i++!=0)
     cout<<++i;
   }

QUESTION: What will be the output of this program?

Answers:

1. No error

2. Error, while loop must have condition.

3. a=10

4. YESNO

5. NO OUTPUT, condition in the while loop is false to begin with.

Hope this helps...

"RTC Battery" stands for Real-Time Clock battery which almost all laptops and PCs have on their motherboard to power the clock and sometimes to also keep the CMOS settings from getting erased while the system is switched off.  It is not uncommon for these batteries to last for years before requiring a replacement as the clock consumes very less power.

Creating a Simple Phone Book in PHP

This is a short follow-up of the post Storing and Retrieving Data from MySQL Database . Here we’ll expand the Phone Book Script that we’ve created to include the following three features: Use an efficient table structure to store data with proper INDEX (primary key) defined. Display previously stored phone numbers in different orders. Include a Search feature to let user easily find the person’s phone number he/she is seeking. To create efficient table Read the MySQL Data Types and Properties post to know more. We’ll create a table having an ID field having serial numbers auto_incremented. We’ll set it to be the primary key. We can do this with the help of the following SQL query: CREATE TABLE phno( id int AUTO_INCREMENT PRIMARY KEY , name varchar( 50 ) , phnum varchar( 20 ) ) Retrieving data in other orders For our table we’d easily be able to retrieve data in the following four orders: Newe

The Best Way(s) to Comment out PHP/HTML Code

PHP supports various styles of comments. Please check the following example: <?php // Single line comment code (); # Single line Comment code2 (); /* Multi Line comment code(); The code inside doesn't run */ // /* This doesn NOT start a multi-line comment block /* Multi line comment block The following line still ends the multi-line comment block //*/ The " # " comment style, though, is rarely used. Do note, in the example, that anything (even a multi-block comment /* ) after a " // " or " # " is a comment, and /* */ around any single-line comment overrides it. This information will come in handy when we learn about some neat tricks next. Comment out PHP Code Blocks Check the following code <?php //* Toggle line if ( 1 ) {      // } else {      // } //*/ //* Toggle line if ( 2 ) {      // } else {      // } //*/ Now see how easy it is to toggle a part of PHP code by just removing or adding a single " / " from th
