Look at the code here:

if (pos != -1)
{
	goto badsearch;
}

I think you meant:

if (pos == -1)
{
	goto badsearch;
}

Another thing is that string::search() returns string::npos if the search function does not find what it was told to find, and not -1, so the code should be:

if (pos == string::npos)
{
	goto badsearch;
}
cout << search;
pos = search.find("=");
if (pos != string::npos)
{
	cout << "\n" << pos;
}

And one last thing: you can avoid using goto in your 'if' statement by replacing it with the statement continue; - this will jump to the beginning of the while loop:

if (pos == string::npos)
{
	continue;
}

Hi all,
what is the bug in the following code:

#include <iostream> 
#include <string>
int main()
{
string str = "Hello World!"
cout << str << endl;
cout << float x = 5.0f * str << endl;
int 65Num = 65;
cout << "65Num = " << 65Num << endl;
}

There are a lot of "bugs" in your code.
Frist, you miss the using namespace std; line before the main() function, so the compiler might not recognize cout and string .
You also missed a semicolon after "Hello World!" .
Another thing is that you can't declare variables inside cout , so you should take float x = 5.0f * str outside cout . The multiplication operation of a float type and string type is not even declared, so float x = 5.0f * str has no meaning. The variable 65Num has an "illegal" name - variables' names cannot begin with a digit.

We won't do your homework. You should provide us some code so we can know you've at least tried.

I think you swapped these two letters
