Find index of vector in c++
WebIndex of vector elements: Each elements of a vector can be accessed by using its index. It works similar to array, i.e. the index of the first element is 0, index of the second element is 1 etc. We can access an element in two different ways: By using the [] operator and By using at () method. Let’s check how to do that with example for both. WebThe 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 …
