Test case 1:
Ener two numbers
: 15 25
Ener an operator (+, -, / ,-)
:+
: 40
Output:
Do you want to continue, exit or compute two numbers? (con, exit, com] exit
<program ends>
Test case 2:
Ener two numbers
: 11.50 6
Ener an operator (+, -, /,-)
:-
Output:
:5.50
Do you want to continue, exit or compute another two numbers? (con, exit, com] con
Enter another number
: 25
Ener an operator (+, -, 7,-)
Output:
