Name Abbreviation Program in C++

In this article, we are going to design a program that abbreviates the first and middle name leaving the last name as it is.

Suppose if the user inputs the following name: William Henry Gates

Then the output of the program would be: W. H. Gates

Without further a due I present you with the Steps:-

  1. We have declared two character arrays (strings), name[4] and abname[30], which stores the name input by the user and abbreviated name respectively.
  2. Suppose if the user inputs the following name: William Henry Gates Then the two arrays would have the following values: Name[40]="William Henry Gates" (unchanged) Abname[30]=EMPTY
  3. The next step is to store the first character of the array name[40] to the abname[30] array and put a dot (.) and a space( ) after it.
  4. Next, we set-up a loop which finds space in the array name[40] (space separates first, middle and last names). As soon as a space is detected the character immediately after the space is stored to the abname[30] array, followed by a dot (.) and a space. Now the two arrays have these values: Name[40]=”William Henry Gates” (unchanged) Abname[30]="W. H. "
  5. Now that we have abbreviated the first and middle name, we need to store the last name as it is. For this, we again search for a space, as it is found, the control goes to the while loop where the whole of the last name is copied to the abname[30] array. Now the two arrays have the following values: Name[40]=”William Henry Gates” (unchanged) Abname[30]="W. H. Gates"


   //C++ program to abbreviate first and middle name
   void main(void)
   char name[40];
   char abname[30];
   int i,len,m=1,j=0;
   //puts is used to print string of characters
   //although cout is equivalent to it but gets
   //and cout should not be mixed in one program
   puts("Enter Name: ");
   //gets is used to take string input with spaces
   //strlen is a built-in function, declared in
   //the string.h header file
   //it returns the length of a string
   abname[j++]=' ';
   for (i=0;i<len;i++)
     if(name[i]==' ')
     if(m==1)//check to see if it is the
     //middle name
       abname[j++]=' ';
       m=0;//middle name has been fetched
     else//if it is not the middle name
       //copy characters until the end of
       //the string is reached which is
       //represented by the \0 constant
   abname[j++]='\0';//put the end of string constant
   puts("Abbreviated Name: ");

Although this program has little or no use as it is, I don’t think there is any harm in learning how things are done.

You may also incorporate this in other programs where you need to do such abbreviations.

Hope this helps…

Fix For Toshiba Satellite "RTC Battery is Low" Error (with Pictures)

RTC Battery is Low Error on a Toshiba Satellite laptop "RTC Battery is Low..." An error message flashing while you try to boot your laptop is enough to panic many people. But worry not! "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. And contrary to what some people tell you - they are not rechargeable or getting charged while your computer or laptop is running. In this article, we'll learn everything about RTC batteries and how to fix the error on your Toshiba Satellite laptop. What is an RTC Battery? RTC or CMOS batteries are small coin-shaped lithium batteries with a 3-volts output. Most laptops use

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

How to Remove Bullet Points in CSS

This will be a short guide on how to remove bullet points from ordered/unordered lists with CSS, you only need two lines of CSS for this. The first removes the actual bullet points and the second one removes the space to the left, as evident from the following video: We'll also be doing some bullet beautification in the last section if that's what you are looking to do. How to Remove Bullet Points in HTML/CSS Now that we know what CSS properties actually accomplish what we want let's see how we can implement this in our HTML code. Using Inline "style" Tag (The quick and dirty way) As the title suggests, this is the quickest way to remove bullet points in which you wouldn't have to edit any CSS files (for example, for Blogger or WordPress). This method would be useful for a one-off case - just add the following " style " attribute to the list you want to remove the bullet points from: <h1>Ordered List</h1> <ol  style="list-styl
