can you use simple operators, and use dev c++ please and thanks

Assuming the temperature on each side of equally sized surfaces is uniform, the rate at which heat flows through a material is given by Fourier's law of heat conduction. The formula is as follows: ho k(T2 -T.) Q W Where: Q is heat per unit time per unit area with units of watts/m? (SI units) or BTU/hr-I? (US Customary units) k is the thermal conductivity of the material with units of watts/mK (Si units) or BTU/hr-ft F (US Customary units). Note: a useful conversion factor is 1 wattmK = 0.5779 BTU/hrft F T2 is the hotter temperature in K (Si units) or F (US Customary units) Ti is the cooler temperature in K (Si units) or F (US Customary units) w is the width of the material in m (SI units) or ft (US Customary units) Program Requirements: Write a C++ program to calculate and display the heat transfer, through a material. The program should do the following: prompt the user for the name of the material prompt the user for the thermal conductivity, k, of the material o the user should be able to enter k in SI or US Customary units prompt the user for the width, w, of the material o the user should be able to enter w with units of m, cm, ft, or in prompt the user for the temperatures on either side of the material o the user should be able to enter the temperatures in F. C. K the program should convert units as necessary so that a consistent unit system (SI or US Customary) is used to calculate check to be sure that inputs from the user are valid: Ok>0 w>0 o temperatures > O'K o T2 >T Units are valid If any bad inputs are entered print out an appropriate descriptive error message and terminate the program using the command: return 1; For Example: if(Q
