C Objective

main()

{
         unsigned int i;
         for(i=1;i>-2;i--)
              printf("c aptitude");
}

Explanation:
i is an unsigned integer. It is compared with a signed value. Since the both types doesn't match, signed is promoted to unsigned value. The unsigned equivalent of -2 is a huge value so condition becomes false and control comes out of the loop.




main(){
          float i=1.5;
   switch(i){
           case 1: printf("1");
           case 2: printf("2");
           default : printf("0");
   }
}
Answer:
Compiler Error: switch expression not integral
