#include<stdio.h> #include<conio.h> main() { char c; clrscr(); printf("Enter the character\n"); scanf("%c",&c); printf("\n The ASCII value of %c is %d",c,c); printf("\n Previous character of %c is %c",c,c-1); printf("\n Next Character of %c is %c",c,c+1); } OUTPUT : Enter the character s The ASCII value of s is 115 Previous character of s is r Next Character of s is t

Scanner is used in JAVA to accept the values from the user through the Standard I/O devices. Below is a basic program to demonstrate the use of scanner : import java.util.Scanner; public class scan { public static void main(String[] args) { Scanner s=new Scanner(System.in); System.out.println("Enter any string"); String a=s.nextLine(); System.out.println("String is :"+a); } }  OUTPUT : Enter any string codeground String is :codeground

This program demonstrates the use of switch() case : #include<stdio.h> #include<conio.h> #include<stdlib.h> main() { int ch; float s,l,b; float arect,asquare; clrscr(); do { printf("\t Main Menu\n"); printf("\t 1. Area of Rectangle.\n"); printf("\t 2. Area of Square.\n"); printf("\t 3. Exit\n"); printf("\n\tEnter your choice:\n"); scanf("%d",&ch); switch(ch) { case 1 : printf("\n\tEnter length and bredth:\n"); scanf("%f%f",&l,&b); arect=l*b; printf("\n\tArea of rectangle is : %f\n\n",arect); break; case 2 : printf("\n\tEnter side of the Square:\n"); scanf("%f",&s); asquare=s*s; printf("\n\tArea of Square is : %f\n\n",asquare); break; case 3 : exit(0); } }
