What is wrong with this code

[mat1989]

Hi guys after doing some research thought I had finally got my program to count html tags correctly. However its not working. When the program is run, it a weird amount for number of tags. The idea I tried was the following

if( str.find("<") !=string::npos && str.find(">") != string::npos)
{
    amounttag++;
}
	
      

The if statement is contained in a while loop and the string " str" is declared at the top of the code as string str("<>")

Could someone tell me what's up.

Thanks

Mat

may help the examples they have here they use the find out side of the if statement... you might try that

though it works

did you give amounttag a value? cuz i tried it and it didnt work tell i set amounttage to 0;

Perhaps if you showed the entire program it would help. Can there be more than one tag, or trick input? In that case, if a tag is any "<" followed by a ">" it seems your boolean might look more like:

while ( str.find("<") < string::npos && str.find(">") > str.find("<"))
{   amounttag++;  //then if >1 tags per str, str.assign(...remainder, if any, of str after first ">"...) 

Also, although it is probably overkill for your small app, there's always regular expressions:
