c++ - How to compare 2 QStringList's and show the results? -

i want know how can compare 2 qstringlist , display results in next way:

i have 2 qplaintextedit , b

in have, example, 10 lines of 6 numbers per line; in b have, example, 100 lines of 6 numbers per line;

what want this: take each line in b , compare lines in a. if, in 1 line-line comparison, 6 equal int n6 (for example) add together 1. if 5 equal, int n5 add together 1 , on.

i've tried few things none of them worked. if give lite on i'll appreciate.

start calculating number of matching digits per string

int matchingdigits(qstring str1, qstring str2) { int matches = 0; int minsize = str1.size() < str2.size() ? str1.size() : srt2.size(); (int pos = 0; pos < minsize; ++pos) { if (str1.at(pos) == str2.at(pos) ++matches; } homecoming matches; }

now compare strings each other (iterating on both stringlists) , if matchingdigits() > 0 can increment result counters.

qstringlist lista; qstringlist listb; foreach (qstring a, lista) { foreach (qstring b, listb) { int matches = matchingdigits(a, b); if (matches > 0) { // fancy } } }
