Problem: A little preprocessor mischief. What output does this program produce? (t does compile and execute without errors.) #include #define magic 13 #ifdef number #define number 17 #endif #mder number #define number 42 #endif #define doubleplus(x,y) x2+y #define plusdouble(x,y) x+2*(y) int main printf("magic number is %d %dn', magic, number) printf("%din", doubleplus(1+2.3+4)); printf("%dn", plusdouble(3+4.1+2)); return 0; Output
