See your code is not working even for sample testcase. This is because your code needs a and b as input even if your ch is invalid. So comment out line 8 and take cin>>a>>b inside each if condition.
Also when ch is invalid, You have to print “Invalid operation. Try again.” you have missed a space after full stop. Check it
