erase range vector c++

To erase a range of elements from a vector in C++, you can use the erase function. Here are the steps to accomplish this:

1. Determine the range of elements you want to erase from the vector. This range is specified by two iterators: the first iterator points to the beginning of the range, and the second iterator points to one position past the end of the range.

2. Call the erase function on the vector, passing in the two iterators that define the range. The syntax for the erase function is as follows: vector.erase(first, last). Here, vector is the name of the vector, first is the iterator pointing to the first element of the range, and last is the iterator pointing to one position past the end of the range.

3. After calling erase, the vector will be modified, and the elements within the specified range will be removed. The iterators and references to the erased elements become invalid and should not be used.

4. If you want to erase a single element at a specific position, you can use the erase function with a single iterator parameter. For example, vector.erase(iterator) will remove the element at the position specified by the iterator.

Remember that when erasing elements from a vector, the remaining elements will be shifted to fill the gaps left by the erased elements.
