SpletThe std::all_of () function is a STL Algorithm in C++. It can be used to check if all the elements of a sequence satisfies a condition or not. The sequence can be a vector, array, list or any other sequential container. We need to include the header file to use the std::all_of () function. SpletIn C++, you can iterate through arrays by using loops in the statements. That is, you can use a “for loop,” “while loop” and “for each loop.”. “For each loop” is the statement just like for loop but there is a small difference in both terms. A “for each loop” has a specific range/limit, however the “for loop” has no ...
