STEP-1 First of all open Visual Basics 6.0 and choose project type as standard EXE STEP-2 Now in form, draw a new label using label tool from general tools section(located in left side of working area). STEP-3 Now go to properties and design lable-1 as required...and in caption, type the first fieldname for bio data, which is 'Name'. STEP-4 Now make labels for all fields like address, class, city, contact no., email address etc. You can also use copy paste option as well but remember to change caption for every field... while copy-pasting...it may show a dialog box asking if you want to create control array, simply choose no. STEP-5 Now add a textbox in front of every field...you can use copy-paste for this as well. Also clear text using text property from properties box. You can also make change into more properties if required... STEP-6 Now add CommandButton using CommandButton tool from general tools section and caption it as 'BIODATA'. STEP-7(Optional) You can also ...

  VARCHAR: The VARCHAR data type is used to store character values. It's fixed value data type means once it's initialized, we cannot change the size at the execution time. So, it's called static data type . It can store maximum 2000 bytes of character data. For each character one byte will be stored in memory. If you store 5 characters in varchar(10), the 5 bytes will be stored in oracle and other 5 bytes will lead to memory wastage. Varchar is external data type. It's ANSI SQL standard and it's definition may change in future by oracle. Varchar can identify null and empty strings separately. VARCHAR2: The VARCHAR2 data type is also used to store character values. It's variable length -data type means it's character value can be changed while execution. So, it's called dynamic data type . It can store maximum 4000bytes of data. For  each character one byte will be stored in memory. Since it's dynamic data type , memory will not wasted. If you stor...

  What is Data? Data is collection of details of any object. It is always related to input. What is Information? Information is what we get after doing proper process on data. It is always related to output. What is Database? Database is a collection of interrelated data. What is DBMS? DBMS or DataBase Management System is a computerized process of efficiently and effectively recording(managing) the data.

  The code for this program is given below: #include<stdio.h> #include<conio.h> void swap(int *x,int *y) { int temp; temp=*x; *x=*y; *y=temp; } int main() { int a , b; clrscr(); printf("Enter Value Of A:"); scanf("%d",&a); printf("Enter Value Of B:"); scanf("%d",&b); swap(&a,&b); printf("After Swapping..."); printf("\nA=%d",a); printf("\nB=%d",b); getch(); return 0; } Output:

 POST -  All the code given below is compiled using turbo CPP and working totally fine but if you are using any new IDE there might be some difference in code... #include<iostream.h> #include<conio.h> void swap (int &x , int &y) {      int temp;     temp=x;     x=y;     y=temp; } main() {      int a, b;      clrscr();      cout<<"Enter The Value Of A : ";      cin>>a;      cout<<"Enter The Value Of B : ";      cin>>b;      swap(a,b);      cout<<"After Swapping..."<<endl;      cout<<"A= "<<a<<endl;      cout<<"B= "<<b<<endl;      getch();      return(0); }  OUTPUT:

POST-3 Introduction to basic parts of computer(Processor, Motherboard, RAM, Floppy Drive, CD/DVD Drive, Hard disk, Monitor, Keyboard, Mouse, SMPS, Printer, Scanner Etc.) Processor: The Processor is an integrated electronic circuit that performs the tasks that run a computer. A processor performs arithmetical, logical, input/output (I/O) and other basic instructions that are passed from an operating system(OS). Most other processes are dependent on the operation of the processor. Each processor is constituted of one or more individual processing units called "cores". Each core processes instructions from single computing task at a certain speed, defined as 'clock speed' and measured in gigahertz (GHz). Increasing clock speed beyond certain point is so difficult and because of this modern computers nowadays have several cores(dual-core, quad-core, octa-core etc.). They work together to process instructions and complete multiple tasks at the same time. Motherboard: Mothe...
