In C++ STL, iswdigit() function is a built-in function that is used to check if the given wide character is a decimal digit character or some other character. This function is present in a cwctype header file in C/C++.What are the decimal digit characters?Decimal digit character are the numeric values ... Read More

Given the task is to show the working of deque::crbegin() in C++.Deque is a double ended queue that gives insertion and deletion at each end i.e. front and back with high performance, in contrast to vector that gives high performance insertion at the end i.e. back only.Also, it provides random ...

Given is the task to show the working of forward_list::emplace_after() and forward_list::emplace_front() functions in c++.A forward_list only keeps linkage with the next element unlike normal list that keeps linkage with the next as well as the preceding elements, which helps iterations in both directions. But forward_list can only iterate in ... Read More
