Convert Centigrade to Fahrenheit
This programming challenge is from an initial C++ programming course I took in Fall 2007. The Chapter (3) was titled “Expressions and Interactivity”.
I post these old academic challenges for a few reasons. One is to demonstrate my programming learning, experience, and progression. Another reason is to make sure my code and solutions are indexed by search engines, so that other beginning programmers may get help if they need it.
3.10: Write a program that converts centigrade temperatures to Fahrenheit temperatures. The formula is:
F = 9/5 * C + 32
F is the Fahrenheit temperature and C is the centigrade temperature.
My solution:

#include
using namespace std;
int main()
{
float cent, fahr;
cout << "What is the Centigrade temperature?" << endl;
cin >> cent;
fahr = 9 / 5.0 * cent + 32;
cout << cent << " degrees Centigrade equals " << fahr;
cout << " degrees Fahrenheit." << endl;
return 0;
}
Here is the capture script I turned in for grading:

What is the Centigrade temperature?
100
100 degrees Centigrade equals 212 degrees Fahrenheit.
