65. #include
int main()
{
printf("%d", printf("%d", printf("%d",543210)));
return 0;
}
Answer:
Explanation:Note: First prints inner message 543210
then its length in outer printf 6 then its length in outer printf 1
Hence output : 54321061

70. #include
main()
{
int x=10,y=-10;
printf("%x \t",x<<2); // %X hexadeciamal value displayed
printf("%x\t",y>>2);
}
Answer:
Explanation:Note : here 16 bit computer is considered.
In bitwise operations if number is +ve then simply specied number of bits shifted in specified direction L or R.
If Number is –VE then 2's complement is used Therefore -10 = 1111 0110 = F5 (2's complement)
after 2positions shift → 1111 1101 → FD
in decimal → 1111 1101→10000 0011 → -03
