C++ need help with vector. I have a text file and input it's content into a struct that holds an array for each entry as a string type.

for example:

struct container{

string ID[10000];

string anotherID[10000];

}

in the text file there is a huge list that looks something like this: 1 abc

3 xyz

1 abc

1 xyz

How can I use a vector to sort these so I can get an output like

ID: 1 and anotherID: abc found 2 time(s)

ID: 1 and anotherID: xyz found 1 time(s)

ID: 3 and anotherID: xyz found 1 time(s)
