How to use the conditional operator?

i know

Code:

(condition) ? true-clause : false-clause

but how do you use an array as the condition, how will the code look?

For example i want to write

Code:

string numbers[5] = {"one","two","three","four","five"};
    
    numbers == "one" ? thumb : again;

thumb and again will replace something else. Don't worry about them.
how do i say that if the numbers array is representing "one" then it replaces as "thumb", otherwise "again".

Like this.

Code:

numbers[i] = numbers[i] == "one" ? thumb : again;

Note that numbers cannot represent "one", because it's an array of strings. numbers[i] can.

Code:

numbers[i] == "one"

won't work because you can't compare strings with the == operator in C. You have to use strcmp().

Bye, Andreas

What does the declaration `string' mean in C, anyway? There is std::string in C++, and there is the string.h header file in C. You probably mean

Code:

char *numbers[5] = {"one", "two", "three", "four", "five"};

As was already mentioned, strcmp() is for comparing strings. However, if you *really* want to compare strings with the == operator, then you must make sure you are comparing objects with the same address:

Code:

char *S_ONE = "one";
char *S_TWO = "two";
/* ... */

int main(void) {
  char *numbers[5] = {S_ONE, S_TWO, S_THREE, S_FOUR, S_FIVE};
  char *s = numbers[2];
  printf("%s\n", s == S_THREE ? "You got it." : "Nope.");
  return 0;
}

Yeah I read string, and assumed it was std::string, not realizing that this is the C forum. In c++ you can compare strings like that, but not C.

Or there's the obvious possiblity that this was posted in the wrong forum.
