What is the output of this C code?
int x = 5;
void main()
{
int x = 3;
m();
printf("%d", x);
}
void m()
{
x = 8;
n();
}
void n()
{
printf("%d", x);
}
Answer: A
Correct answer: 8 3
main declares a local x = 3, which shadows the file-scope x = 5 inside main only. m is outside that scope, so its x = 8 assigns to the global, and n prints that 8. Back in main, the local is still 3.
