After declaring a pointer, we have to initialize the pointer with the standard variable address. If pointers are not initialized then there may be a problem in the output. Syntax:pointer= &variable; Example:p= &a; Types of Pointers in C ...

Here in the above example, the 'extra' is an array, and 'friends' and 'ban_firends_id' are subarrays. Geospatial Index To support efficient queries of geospatial coordinate data, MongoDB provides two special indexes: 2d indexes and 2sphere indexes uses for planar geometry when returning resu...
When you apply a decorator to a function, the decorator creates a new function that wraps the original function with some additional behavior. The resulting wrapped function can then be called just like the original function, but with the added behavior provided by the decorator. For example, co...
