hi,
I am reading data from a text file into a multiset. After getting all the data into the multiset, I want to compare the value in each element of the container(unsorted) to the previous one.
I tried using an iterator, but unfortunately, the iterator sorts out the values, and the results become meaningless.
how do I run a compare in a multiset of the raw data copied from the text file?
this is the relevant code I have so far:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15
std::multiset<int> test;
std::multiset<int>::const_iterator iter;
std::ifstream p("f.txt");
if(p.is_open())
{
while(p>>x)
{
test.insert(x);
std::cout<<"x is: "<<x<<std::endl;
}
for(iter=test.begin();iter!=test.end();iter++)
std::cout<<"value is "<<*iter<<std::endl; //this shows the data sorted in ascending order
}
else std::cout<<"unable to open file! "<<std::endl;
