erase element from vector c++

To erase an element from a vector in C++, you can use the erase() function provided by the standard library. Here are the steps to do so:

1. Determine the position of the element you want to erase from the vector.

2. Use the erase() function by providing the iterator pointing to the position of the element you want to remove.

3. The erase() function will remove the element at the specified position from the vector.

4. After erasing the element, the size of the vector will be reduced by 1, and the elements following the erased element will be shifted to fill the gap.

5. Ensure that the iterator used with the erase() function is still valid after the operation, as it may be invalidated by the erase operation.

6. Verify the vector after the erase operation to ensure that the element has been removed as intended.
