Learn C with example
Input an alphabet and change its case
In this example we will learn how we can
convert cases of an alphabet. In this we have enter an alphabet. If it is
character between (a-z or A-Z). Then case will converted and if not then
"Have entered alphabet is not character.....:)" message will
display on screen.
In this we are including two header files
of C library #include<stdio.h> and #include<conio.h>.
In this example we are including five
predefined method. These are main(),clrscr(),printf(""),scanf()
and getch(). Here we are using scanf() method is used to take
input from keyboard.
In this we are declaring ch
as a character variable. Then print a message to enter a alphabet .When you
insert a alphabet then check .Is it between 65 -90?These are ASCII values
for A(65) -Z(90).If it is then to make lower case add 32 which gives equivalent
lower case of alphabet. else if character is between 97(a)-122(z) then
the alphabet is lower case. Then we have subtract 32 else alphabet
is not upper or lower character .Then print message "Have entered
alphabet is not character.....:)".
/* input an alphabets and change its case */
#include<stdio.h>
#include<conio.h>
void main()
{
char ch;
clrscr();
printf("Enter an alphabet:\t");
scanf("%c",&ch);
if(ch>=65 && ch<=90)
{
ch=ch+32;
printf("You have enter a Caps Latter");
printf("/n The lower case is =%c",ch);
}
else if(ch>=97 && ch<=122)
{
ch=ch-32;
printf("Change in to uppercase=%c",ch);
}
else
printf("Have entered alphabet is not character.....:)");
getch();
}

Output Of Example
Enter an alphabet: a
Change in to uppercase=A |
