C Program To Accept A Character And Determine Whether It’s Upper Case Or Lower Case.

Q17. Write a C program to accept a character and determine whether it’s upper case or lower case.

Solution:

#include<stdio.h> //standard input/output header file

#include<conio.h> //for clrscr()

 

int main()

{

char a;

 

clrscr(); //for clearing the screen

 

printf(“\n Enter any character: “);

scanf(“%c”,&a);

 

a>=90?printf(“\n It is a lower case letter.”) :printf(“\n It is an upper case letter.”);

 

getch(); //holds the screen until any key is pressed

return 0; //makes main() finish

}

 

OUTPUT:

CASE 1:

 

Enter any character: r

 

It is a lower case letter.

 

CASE 2:

 

Enter any character: R

 

It is an upper case letter.
