Program 12_1.java Write a program as follows: prompt the user to enter a positive value of type byte. cast this input first to type int and then to type char. if the char is a printable ASCII character (from 32 to 122 ), display it. if the user's input is bad, the program should end gracefully with an error message. Sample Run 1 Enter a positive byte value 67 In ASCII, that is character C Sample Run 2 Enter a positive byte value 300 Bad input. Run program again Sample Run 3 Enter a positive byte value twelve Bad input. Run program again
Control structures
Control structures are block of statements that analyze the value of variables and determine the flow of execution based on those values. When a program is running, the CPU executes the code line by line. After sometime, the program reaches the point where it has to make a decision on whether it has to go to another part of the code or repeat execution of certain part of the code. These results affect the flow of the program's code and these are called control structures.
Switch Statement
The switch statement is a key feature that is used by the programmers a lot in the world of programming and coding, as well as in information technology in general. The switch statement is a selection control mechanism that allows the variable value to change the order of the individual statements in the software execution via search.
Write a program as follows:
- prompt the user to enter a positive value of type byte.
- cast this input first to type int and then to type char.
- if the char is a printable ASCII character (from 32 to 122 ), display it.
- if the user's input is bad, the program should end gracefully with an error message.
Sample Run 1
Enter a positive byte value 67
In ASCII, that is character C
Sample Run 2
Enter a positive byte value 300
Bad input. Run program again
Sample Run 3
Enter a positive byte value twelve
Bad input. Run program again
