Main Question or Discussion Point

The circuit shown in the attachment is a clamper circuit. I want to know that during the first half of the positive input cycle the capacitor charges through the diode, but as soon as the capacitor starts charging its left plate will become negatively charged so it should make the diode reverse biased, then how the further charging of the capacitor is possible ?

The capacitor gets charged for only once (to the peak) and then it never gets discharged.
The Voltage waveform shown is that across the diode, which is applied voltage minus the constant capacitor voltage.
