O_oUnless its operand is a variable length array, sizeof does not evaluate its operand.
I think the statement could use some code.
SomaCode:#include <stdio.h> void DoSomething1() { printf("%zu\n", sizeof(char[printf("Hello, World!\n")])); } void DoSomething2() { printf("%zu\n", sizeof(printf("Hello, World!\n"))); } int main() { DoSomething1(); DoSomething2(); return(0); }
