Thank You Sir for taking this session!! Though i missed the live streaming but now i had listened to the recording and this is really helpful in knowing the inner implementation of arrays.

But according to java language specification, arrays, in java, will store elements in contiguous memory location may not be true because that depends on the JVM. it may or may not store. Now my doubt is how will array work in the other cas ewhn elements aren't stored on contiguous locations?

Hi,
How the compiler knows the starting address of an array

[prathibhar]

Sir, please make a detailed video on STL in C++ for beginners, pls provide example programs for the same.
Thank you Sir.
