It whatever doesn't work
The line "int A, B, C;" should be "double A, B, C;" if you want
to be able to operate non-integer lengths as well.
The lines like "readf("%lf", %A);" should be "readf(" %s",
&A);".
Please read the reasoning again carefully in Ali's book:
http://ddili.org/ders/d.en/input.html. The " %s" can be " %f"
but not " %lf" (that would be the correct string for C's printf
but not for D's readf), and the leading space is important.
On the output line, you perhaps meant "writefln" instead of
"writefl". Again, "%lf" should be changed into "%f" or "%s".
import std.stdio;
import std.math;
void main() {
writef("Enter side A: ");
double A;
readf("%s", &A);
writef("Enter side B: ");
double B;
readf("%s", &B);
writef("Enter side C: ");
double C;
readf("%s", &C);
writefln("Perimetr is", A + B + C, " centimetrs.");
return 0;
}
Is there smth wrong again?
