Write a function mostExpensive that:
• takes as argument a string, filename, which is the name of a text file containing lines looking like this:
bicycle ??? dollars
• The function finds the most expensive item in the file and returns it (as a string).
For example, suppose that file \"inventory.txt\" has these contents:
bicycle 80 dollars
table 150 dollars
chair 40 dollars
watch 25 dollars
Then: mostExpensive(\"inventory.txt\") returns \"table\".
Solution
#include<iostream>
#include<fstream>
#include<string>
using namespace std;
string mostExpensive(char* filename){
ifstream infile;
infile.open (filename);
string s,smax,dollar;
int n,nmax;
infile>>smax;
infile>>nmax;
infile>>dollar;
while(infile>>s){
infile>>n;
infile>>dollar;
if(n>nmax){
nmax = n;
smax = s;
}
}
return smax;
}
int main(){
cout<<mostExpensive(\"inventory.txt\");
return 0;
}
.
