WebSIMD stands for single instruction, multiple data. SIMD allows us to give vector instructions which will allow the code to run faster. Vector instructions are instructions that handle short (length 2-16) vectors of integers / floats / characters in a parallel way by making use of the extra bits of space to do operations simultaneously. WebNow let us look at friend classes in C++. So far that we have an example here. Here we have a class called My and it is having only one private member that is integer a of value 10. Then we have another class called Your which is taking an object m of My class. This is having has a relationship. lyfe flyte hosting
