i need help in c++ program I'm asked to make a phone book which can sort all the names in it alphabetically plllllz i need help

Why don't you show us what you have started and we'll go from there. If you have nothing started start and you'll be more likely to get help.

i don't have a clue a bout the sort i've tried many functions from the internet but they didn't work but i've began in the other function in the phone book and that is what i get thnx
