You can use a “ for loop ,” “ while loop ,” and for “ each loop .”. Here we learn C++ iteration or C++ loop through array in all these loops one by one. The easiest method is to use a loop with a counter variable that accesses each element one at a time.
While you can probably achieve what you want with std::shift_right, the appropriate algorithm to do what you've described is std::rotate, which you can use without c++20 as well: std::rotate (seq.begin (), seq.end () - 1, seq.end ()); Here's a demo. The reason the shift_right version doesn't work is that you have an iterator to the last element. WebOct 28, 2024 · insert (): This function is used to add a new element before a specified position inside the vector. erase (): It is used to remove the element from the container at a specified position or a range. swap (): It is used to swap the contents between the vectors, but it should be of the same type.

WebSyntax : vector_name.push_back (pushvalue) this pushes the value passed as the parameter to the calling vector. In our case, vec.push_back (i); this function call pushes the current value of i to the vector. Therefore, the vector will contain the numbers from 1 to 10 at the end of the loop.
