QT QBytearray count character

Question

How I can count characters in QByteArray, for example I have QByteArray and I want to know how many "*" in this array.

Answer 1

From QByteArray documentation:

int QByteArray::count ( const char * str ) const

This is an overloaded function.

Returns the number of (potentially overlapping) occurrences of string str in the byte array.

count.

Answer 2

You could use QByteArray::indexOf(char ch, int from = 0) const inside a loop.

Maybe this:

int i = 0, counter = 0;

while((i = array.indexOf("*", i)) >= 0)
 counter++;
