+**Задание**:
+
+Let's get some object to be controlled. We want to control its temperature, which can be described by this differential equation:
+
+$$\Large\frac{dy(\tau)}{d\tau}=\frac{u(\tau)}{C}+\frac{Y_0-y(\tau)}{RC} $$ (1)
+
+where $\tau$ – time; $y(\tau)$ – input temperature; $u(\tau)$ – input warm; $Y_0$ – room temperature; $C,RC$ – some constants.
+
+After transformation we get these linear (2) and nonlinear (3) models:
+
+$$\Large y_{\tau+1}=ay_{\tau}+bu_{\tau}$$ (2)
+
+$$\Large y_{\tau+1}=ay_{\tau}-by_{\tau-1}^2+cu_{\tau}+d\sin(u_{\tau-1})$$ (3)
+
+where $\tau$ – time discrete moments ($1,2,3{\dots}n$); $a,b,c,d$ – some constants.
+
+Task is to write program (**С++**), which simulates this object temperature.
+
+Пример вывода программы:
+
+``` bash
+Enter the value for constant a: 1
+Enter the value for constant b: 2
+Enter the value for constant c: 3
+Enter the value for constant d: 4
+Enter the initial value for current temperature, y: 10
+Enter the initial control value, u: 5
+Enter the number of iterations, steps: 5
+
+Linear model simulation:
+Step 1: y = 20
+Step 2: y = 30
+Step 3: y = 40
+Step 4: y = 50
+Step 5: y = 60
+
+Nonlinear model simulation:
+Step 1: y = 25
+Step 2: y = -163.836
+Step 3: y = -1402.67
+Step 4: y = -55075.8
+Step 5: y = -3.99004e+06
