is Dev C++ stupid? Or......

I am trying to do string compares......I need to compare a user entry (stored in a string variable) against the elements of an array, until a match is found. Only trouble is, the compiler will not allow anything but a constant. That makes the function kind of useless, unless there is something specific I need to do.

You can't compare char* strings with ==. You need to use strcmp.

If you're using C++ you might want to try the C++ STL String class instead, it overloads the == operator so I can do this:

Code:

---

string stuff = "ASDF";
if("ASDF" == stuff) {
 //...
}

---

Nope.

In most cases, the general rule is:

"THE COMPILER IS NEVER WRONG. YOU ARE."

You don't think compilers are tested? They're beta tested out the ass....and in-house tested like mad before they even become beta versions...by many experts. Of course, this doesn't mean they're perfect.

Krak had to add in that last part because of Micro$oft. :p

That's just it.

Code:

---

strnicmp(char* yourmom,YourMom[i]) //within an index loop

---

I always get a 'cannot convert std::string to 'const' message.
If I put in constants as the arguments, it works, but that obviously defeats the purpose of the function.

Code:

---

strnicmp(char* yourmom,YourMom[i])

---

No semicolon (although I assume you have one in).
That char* shouldn't be there.
strnicmp() is a non-standard function.

Try string_variable.c_str().

You're definitely taking a backward step if you're trying to use strcmp() and one of the strings in question is a std::string.

Code:

---

#include <iostream>
#include <string>
using namespace std;
int main ( ) {
  string foo = "hello";
  if ( foo == "hello" ) {
    cout << "success" << endl;
  }
  return 0;
}
