After line 8 has been executed we go round the main loop a second time. Operator ends up holding the character '*' and Operand ends up holding the value 3. The case statement executes line 9, which multiplies Result (3) by Operand (also 3) to give a new value of 9 for Result. Around the loop again, and Operator ends up holding a full stop at line 4. The result (9) is then displayed by line 5 before exiting from the main loop at line 6. g. ’) the section of the case statement at line 10 gets executed, which displays an error message.
Text_IO you will also discover the following procedure specification: procedure Put_Line (Item : in String); Put_Line is the same as Put except that it starts a new line after displaying the string supplied as its parameter; in other words, Put_Line is the same as Put followed by New_Line. "); end Hello; Input and output of integers is a bit more elaborate than it is for strings. Integer_Text_IO looks like this: procedure Put (Item : in Integer; Width : in Field := Default_Width; Base : in Number_Base := Default_Base); What this means is that there are two extra parameters called Width and Base which can be used when displaying integers.
2 Modify the calculator program so that after evaluating an expression it asks the user if he or she wants to evaluate another expression. If the answer is ‘y’ or ‘Y’ (yes), evaluate another expression; if it’s ‘n’ or ‘N’ (no) exit from the program. ’ to distinguish cats and dogs from elephants and giraffes.
