Теория информации ! Опишите два точных сравнения различных кривых, описывающих зависимость вероятности появления ошибочного бита от отношения (E с индексом b / N-нулевое).

Добрый день! К сожалению я не работаю с C++, но если это то вот эта задача в Pascal VAR a,b,c,d:REAL; PROCEDURE Print_S(x,y,z:REAL); VAR p,S:REAL; begin If ((x+y)>z) and ((x+z)>y) and ((y+z)>x) then begin p:=x+y+z; S:=SQRT(p*(p-x)*(p-y)*(p-z)); WriteLn('S= ',S); end else Writeln('Треугольник не существует!'); end; BEGIN Write('a= '); ReadLn(a); Write('b= '); ReadLn(b); Write('c= '); ReadLn(c); Write('d= '); ReadLn(d); WriteLn; WriteLn('Стороны ',a,'; ',b,'; ',c); Print_S(a,b,c); WriteLn; WriteLn('Стороны ',a,'; ',b,'; ',d); Print_S(a,b,d); WriteLn; WriteLn('Стороны ',a,'; ',c,'; ',d); Print_S(a,c,d); WriteLn; WriteLn('Стороны ',b,'; ',c,'; ',d); Print_S(b,c,d); END.
