+**Задание**:
+
+Let's consider the wrong object, the control of which consists of controlling its temperature, described by the following differential equations:
+
+After transformations we have the following linear (2) and nonlinear (3) models:
+
+The goal is to write a program in C++ that will simulate the temperature of a given object.
+
+Пример вывода программы:
+
+``` bash
+Enter the constant alpha for the model: 0.08
+Enter the constant beta for the linear model: 0.06
+Enter the constant gamma for the nonlinear model: 0.02
+Enter the constant delta for the nonlinear model: 0.01
+Enter the initial temperature (initialTemp): 20
+Enter the number of discrete time moments: 5
+Enter the heat values (heatInput) for each time moment:
+heatInput[1]: 10
+heatInput[2]: 15
+heatInput[3]: 20
+heatInput[4]: 25
+heatInput[5]: 30
+
+Linear Model Simulation:
+Time 1: Temperature = 20
+Time 2: Temperature = 2.2
+Time 3: Temperature = 1.076
+Time 4: Temperature = 1.28608
+Time 5: Temperature = 1.60289
+
+Non-linear Model Simulation:
+Time 1: Temperature = 20
+Time 2: Temperature = -22.2054
+Time 3: Temperature = -31.0548
+Time 4: Temperature = -59.9394
+Time 5: Temperature = -219.86
