/*Above program a charcter is entered.using logical operator AND entered character's ASCII value is 
checked.If it is in between 65 to 90,the result displayed will be 1 otherwise 0.*/

The above program takes a character as input from the user and stores it in the variable x. The value of y is then evaluated using a conditional operator that checks if the ASCII value of x is between 65 and 90 (the range of uppercase letters in the ASCII table). If it is, y will be assigned the value 1, otherwise, it will be assigned the value 0. Finally, the value of y is displayed on the screen.
