Print statement

A statement in a program that displays the variables, object, or text to the output device (screen) is known as a print statement. The print statement consists of a function that forwards the output to standard output devices such as printers, monitors, etc. Depending on the programming language, the syntax of the print statement differs. The print statement allows the user to print the values of multiple variables in a single statement; however, the variables are separated using a separator (comma, plus, etc,).

Question

A. Trace the following pieces of code and give their exact output.
i.
int p
27;
switch (--p) {
case 28: System.out.println ("bbbb"); break;
case 27: System.out.println("abab"); break;
case 26: System.out.println ("aaaa");
default: System.out.println("@@ @ @ " ) ;
}
System.out.println(" After switch: P =
" + p);
ii.
int a = 100, b
17;
System.out.println (a%b);
System.out.println(a/b);
System.out.printf("%.3f\n",(double)a/b);
