Re: Number of commas
Consider:
Code:
#include <atlstr.h>
#include <stdio.h>
int count(const CString& cstr, char ch)
{
int cnt = 0;
for (int pos = -1; (pos = cstr.Find(ch, pos + 1)) >= 0; ++cnt);
return cnt;
}
int main()
{
const CString tst = ",qw,asd,zxc,";
printf("Number of ',' in '%s' is: %i\n", tst.GetString(), count(tst, ','));
}
giving:
Code:
Number of ',' in ',qw,asd,zxc,' is: 4
