Using namespace std; The expansion of a steel bridge as it heated to a final Cel

Question

Using namespace std;

The expansion of a steel bridge as it heated to a final Celsius temperature, Tf, from an initial temperature T0 , can be approximated using the following formula:

Increase in length= a* L*(Tf-T0). Where a is the coefficient of expansion that is for steel is 11.7e-6, L is the length of bridge at temperature T0.

Using this formula, write a C++ program that displays a table of expansion length for a steel bridge that’s 7365 meters long at 0 degrees Celsius, as the temperature increases to 40 degrees in 5 degree increments.

Explanation / Answer

#include <bits/stdc++.h>
using namespace std;
float Length(int Tf)
{
const float a = 11.7E-6;
const float L = 7365;
const float To=0;
return a*L*(Tf-To);
}

int main(int argc, char const *argv[])
{
   cout<<"Intitial Temperature Final Temperature Increased Length ";
   for (int i=1;i<=8;i++)
       cout<<0<<" degrees "<<i*5<<" degrees "<<Length(i*5)<<endl;

  
   return 0;
}
