You can use Macro Arguments to change the output of printf(). #include stdio.h void fun() { #define printf(x, y) printf(x, 10); } int main() { int i = 10; fun(); i = 20; printf("%d", i); return 0; }

U should use the concepts of functions to get this answer . By using the function we should use the return statements accordingly.
