Array input and output in C programming

Loops are used for array input/outputs. To access the individual elements of array, we use subscripts as a[subscript], where subscript could be a constant integer like 0 , 1, 5 or a integer variable like i, j or a integer expression like (i+j+2). One important thing to note is that the value of subscript should be integer. e.g:

#include<stdio.h>

#include<conio.h>

void main()

{

int a[10], i;

clrscr();

printf("Enter 10 numbers:\n");

for(i=0;i<10;i++)

scanf("%d",&a[i]); /* array input */

printf("\n You have entered these 10 numbers:\n");

for(i=0;i<10;i++)

printf("\t%d",a[i]); /* array output*/

getch();

}

This example shows how to input array elements by users and output them. This program asks 10 integers from user and then displays these numbers.

Database Management System(DBMS)

Data and Information Data is an unprocessed raw fact which does not give complete meaning about any object,person, entity etc. But when various inter-related data arranged in a row, it gives a complete meaning which is referred to as information.

What is Java Applets?

An applet is a special kind of Java program that is designed to be transmitted over the Internet and automatically executed by a Java-compatible web browser. Furthermore, an applet is downloaded on demand, without further interaction with the user. If the user clicks a link that contains an applet, the applet will be automatically downloaded and run in the browser. Applets are intended to be small programs. They are typically used to display data provided by the server, handle user input, or provide simple functions, such as a loan calculator, that execute locally, rather than on the server. In essence, the applet allows some functionality to be moved from the server to the client.
