1. Look at the code below (funny question)
void main() { if(X) { printf("Hello"); } else { printf(" World"); } }What should X be replaced with inorder to get the output as "Hello World"?
And here comes the answer....
#include int main(){ if(!printf("Hello")) { printf("Hello"); } else { printf(" World"); } }
2.
#include
int main()
{
int i=448;
printf("%d\n",printf("%d",printf("%d",i))); return 0;
}
Output: 44831
3.
main()
{
int i=0;
for(;i++;printf("%d",i)) ;
printf("%d",i);
}
Answer:
1
Explanation:
before entering into the for loop the checking condition is "evaluated".
Here it evaluates to 0 (false) and comes out of the loop, and i is
incremented (note the semicolon after the for loop).
