How do we declare double data type for C in sololearn IDE?

Question

I'm working on an apps and I'm using double data type because my apps involves real number but sololearn IDE cannot read my input if I use %f or %lf as conversion specifier? How do I solve this?

Answer 1

#include <stdio.h>

int main() {
double test;
scanf("%lf", &test);
printf("%f", test);
}
