how is iostream and <bits/stdc++.h>
that i saw most expert use in their video.
STL lib how to master it? can u suggest some good source online
Header file c++
hello @Kash-Moulik-3715574511847721 there is nothing to master about the header files .
all you need to learn is that all the header files are contained in the bits/stdc++.h and iostream is the sublibrary which is also there in bits/stdc++.h
with practice you will learn what operations are not there in iostream and why you have to use bits/stdc++.h
still read this you will be able to understand in the better way :
if you dont understand anything you can ask here .
Happy Learning !!
can u give examples of such operators?
like if you want to perform string operation then you have to include cstring library ,if you want to use vectors in place of arrays then you have to use vector etc etc.
