Currently I am working on program where input is in the range 10^-6<=x<=10^6,and hence I want to use int64_t, but can't figure out how to take input using it.Please help!!

1`scanf` with the right specifier? – M.M Sep 01 '17 at 05:38

3There seems to be something missing from the question, since `10^-6` needs some sort of transformation before it can be represented as a `int` – user3386109 Sep 01 '17 at 06:06

1`10^-6` is `0.000001` and not an integer. Please explain coding goals. – chux - Reinstate Monica Sep 01 '17 at 19:24

The portable way is to use <inttypes.h> and do
scanf("%" SCNd64, &your_variable)

try this
int64_t x;
scanf("%lld", &x);
printf("ans is %lld", x);

There is no guarantee that `int64_t` is the same as `long long`, and you get undefined behavior if that's not the case. Use the format in Jabberwock's answer instead. – cmaster - reinstate monica Aug 31 '20 at 13:23
