Hi,
Could any explain the below code.
The output of the above code is 12, but if I try as below it gives error why is it so, and if any know about the tutorial on such things please let me knowCode:#include<stdio.h> #include<string.h> #define f(a,b) a##b int main() { printf("%d\n",f(1,2)); }
Code:#include<stdio.h> int main() { printf("%d\n", 1##2); }
