if u want to remove the value whose index value you dont know then how do you remove that value from the vector?

to use erase, we need to use iterators and we need the exact location of the element to be deleted. how do we get the exact location of the element we want to delete in a vector.

You do exaclty what you say. Iterate through the elements. Start at the first one and see if it mathces the data you want to delete. If it doesnt move on to the next one. Try it out yourself, if you are having problem with the code, post your code here (inside some code blocks) so we can have a look at it and see how we can help you.
