Debug the following code. When it runs, it prints out "That is NOT correct!" no matter what the user enters. Why is this occurring and how do you fix it:

#include

int main (int argc, char* argv { } )

{

int a=42, b-42;

int answer;

print ("What is %d-%d ", a, b);

scanf ("%d", &answer);

if (answer=0)

{

printf ("That is correct! ");

}

else

{

printf ("That is NOT correct!");

}

return 0;

}
