Programs using characters in C++

Character:
/* write a program to demonstrate character*/
#include<iostream.h>
#include<conio.h>
void main()
{
char ch=’c’;
clrscr( );
cout<<“\nch=“<<ch;
getch( );
}

Result:

Output:

Ch=c
#include<iostream.h>
#include<conio.h>
void main()
{
char ch;
clrscr( );
cout<<“enter the character:”;
cin>>ch;
cout<<“\nch=“<<ch;
getch( );
}

Result:
Input:
Enter the character: p

Output:
Ch=p

Note: with using characters we can perform arithmetical operations.
program
#include<iostream.h>
#include<conio.h>
void main()
{
char ch;
clrscr( );
cout<<“enter the character:”;
cin>>ch;
ch=ch+1;
cout<<“\nch=“<<ch;
getch( );
}

Result:
Input:
Enter the character: k

Output:
Ch=l

/* write a program to convert uppercase to lowercase alphabet*/
/* write a program to convert lowercase to uppercase alphabet*/
#include<iostream.h>
#include<conio.h>
void main()
{
char ch;
clrscr( );
cout<<“enter the upper case alphabet:”;
cin>>ch;
ch=ch+32;
cout<<“\nch=“<<ch;
getch( );
}

Result:
Input:
Enter the uppercase alphabet: A

Output:
Ch=a
#include<iostream.h>
#include<conio.h>
void main()
{
char ch;
clrscr( );
cout<<“enter the lower case alphabet:”;
cin>>ch;
ch=ch-32;
cout<<“\nch=“<<ch;
getch( );
}

Result:
Input:
Enter the lowercase alphabet: k

Output:
Ch=K



/* write a program to find given alphabet is vowel or not using else if */
/* write a program to find given alphabet is vowel or not using switch */
#include<iostream.h>
#include<conio.h>
void main()
{
char ch;
clrscr( );
cout<<“enter the alphabet:”;
cin>>ch;
if(ch==’a’||ch==’e’||ch==’I’||ch==’o’||ch==’u’)

{
cout<<“it is lower case vowel”;
}
else  if(ch==’A’||ch==’E’||ch==’I’||ch==’O’||ch==’U’)
{
cout<<“it is upper case vowel”;
}
else
{
cout<<“it is not a vowel”;

}
getch( );
}

#include<iostream.h>
#include<conio.h>
void main()
{
char ch;
clrscr( );
cout<<“enter the alphabet:”;
cin>>ch;
switch(ch)
{
case ‘a’:
case ‘e’:

case ‘i’:

case ‘o’:

case ‘u’:

cout<<“it is lower case vowel”;
          break;
case ‘A’:
case ‘E’:

case ‘I’:

case ‘O’:

case ‘U’:

cout<<“it is upper case vowel”;
        break;

default:
cout<<“it is not a vowel”;
         break;

}
getch( );
}
Result:
Input:
Enter the alphabet: A

Output:
it is vowel
Result:
Input:
Enter the alphabet: A

Output:
it is vowel
