The question is:
  Yesterday my friend had taken interview in Microsft.If u know this
Plz answer this

main()   // line 1
{
   printf("TWO");



}   //line4


U don't change from line1 to line4.  u will add anything before the
main function only.
write the solution with 10 ways.
We want the ouput is->

One
Two            //注意，不是TWO！
Three

There are several ways to solve the question, the following is:
First：to ignore the main funcion
#include <stdio.h>
int main(int argc, char *argv[])
{
        printf("One\nTwo\nThree\n");
        return 0;
}

#define main XXX

main()   // line 1
{
   printf("TWO");



}   //line4

The second way:To ignore the printf function
int xxx(const char* x)
{
        return printf("One\nTwo\nThree\n");
}
#define printf xxx

main()   // line 1
{
   printf("TWO");



}   //line4

The last way: using struct
#include <stdio.h>

struct Foo
{
        Foo(){printf("One\nTwo\nThree\n");exit(0);}
}foo;

main()   // line 1
{
   printf("TWO");



}   //line4
