In your circuit, both switches must be closed to charge the capacitor. If either or both switches are opened the capacitor will not discharge but will retain the voltage it has when the switch is opened. Closing the both switches again will allow charging to continue until the capacitor voltage reaches 100V. Your circuit will not allow discharge.
