How and Why ?

• *str is Pointer Variable and AddressOf(1+”Pritesh”) is Assigned to Pointer Variable
• It Tells that Address of “r” is Assigned as “Starting / Base Address”
• Refer : Here to Learn How to Solve printf(1+”%d”) type Problems ?.
• So Initially “ritesh” is Assigned to String Type Variable.

*str = "ritesh"

• Before Printing “str + 1″ prints “itesh”
