Answer / susie

Answer :

You can answer this if you know how values are
represented in memory

Explanation

~ (tilde operator or bit-wise negation operator) operates on
0 to produce all ones to fill the space for an integer. –1
is represented in unsigned value as all 1’s and so both are
equal.

#include<stdio.h> #include<conio.h> void main() { int a=(1,2,3,(1,2,3,4); switch(a) { printf("ans:"); case 1: printf("1");break; case 2: printf("2");break; case 3: printf("1");break; case 4: printf("4");break; printf("end"); } getch(); }
