scanf is not a safe function. It trusts the format string and assumes that 'a' really is what the programmer told it. (For example, although 'a' is not an 'int, %d means 'int' and scanf treats it as such.)

The correct format identifier for double is %lf. You need to replace all three of with %lf.

However, you are not writing idiomatic D code. I recommend dropping C functions altogether an taking advantage of readf():

module main;

import std.stdio;
import std.math;

int main() {
        int A, B, C;
        writef("A = ");
        readf("%lf", %A);

        writef("B = ");
        readf("%lf", %B);

        writef("C1= ");
        readf("%lf", %C);

        writefl("P = (%lf)", A + B + C);
        return 0;
}

It whatever doesn't work
