Question
COMP163 Pipe Length A plumbing company has a large inventory of pieces of pipe of various lengths. The data file pipeLength.txt contains a list of numbers representing the length of pieces of pipe. Each line of the file contains a number with a decimal point followed by the unit of measurement. The units can be ft, inch or m. The units might be in a mixture of upper and lower case. A. [85 points] Write a program that sums the length of all the pieces of pipe and displays the total length in meters. There are 0.3048 meters in a foot and 12 inches in a foot. B. [15 points] Display the sum of the pipe lengths with only three decimal digits of accuracy. Sample output The total length is 12021.326140600006 meters or The total length is 12021.326 meters

Explanation / Answer
#include<iostream>
#include<fstream>
#include<iomanip>
#include<string.h>
using namespace std;
int main()
{
ifstream f("pipeLength.txt"); //to read file
long double a,sum=0;
string s;
while(f>>a>>s) //read until end of file
{
//below,if s equals inch (after ignoring case and s.c_str() means, convert s to char array as the function needs it)
if(!strcasecmp(s.c_str(),"inch"))
{
a=a*(.0254);//to metre
}
if(!strcasecmp(s.c_str(),"ft"))
{
a=a*(.3048);//to metre
}
sum=sum+a;
}
//fixed, tells the cout to show without rounding all decimals, and setprecision, sets its rounding decimal places
cout<<"Total length = "<<fixed<<sum<<" m and also upto 3 decimal places, total length = "<<setprecision(3)<<fixed<<sum<<" m";
}
