Exercise 7, spring 2006 ----------------------- Get familiar with standard library's(STL) containers. Examine the following containers in particular: vector, list, string and map - what they are and how to use them. A few basic things to find out: -Vector/list: Adding and removing elements, accessing elements. -String: using with cout/cin, behavior of operators =, +, == etc. -Map: Adding/finding elements As an example: 1.Create a program that asks strings from user and adds them to a list - loops until user enters for example "stop". Then it creates a new string which is the 'sum' of strings in the list - so if the list would have strings "a", "b" and "c", then the 'sum string' was "abc". 2. Create a simple 'examresultlist' with map. The 'key' could be the name of the participant, and the 'value' the grade. Test it with main program.
