How to select any one from QStringList array that satisfies conditions?

Question

Qt

First I add the words to the array:
mtowns << line;
Then I need to find a word that starts with a certain letter.
I do it through a loop:
for(i=0;i<count;i++)
And if it satisfies the conditions, then I show the result.
How can I make a random word output to this letter, and not just the first one that came up?

Answer 1

for etc. - not the best practice, try using the standard function mtowns.filter(QRegEx("ваш образец для поиска"))
