hello @pd.pankajdahiya
…

pls share that question with me in which u have doubt

#3

Q9. bitmask 1<<32 32 bit long long x = (1 << 32) ; What will be the value of x ?

#4

it will result in compilation error. because 1 is int and we can shift it till [0…31] not more than that.

#5

In answer there are 4 options- compile error, 2^31, 2^32, none(correct), so is it a runtime error and why?

#6

its a compile error. compiler will check this thing at the time of compiling

u can run the same program and check

#7

Finished in N/A Line 2: Char 23: runtime error: shift exponent 32 is too large for 32-bit type ‘int’ (solution.cpp) SUMMARY: UndefinedBehaviorSanitizer: undefined-behavior prog_joined.cpp:7:23

your compiler might not be checking this at compile time.

#9

But the solution of the questions says its none of the above so finally its a warning/runtime . is it?

#10

…

its compilation error->
