Question

I am using programming language of DEV C++, and here is my assignment.

Write a program, maxmin.c to find the maximum and minimum of values in the file maxminin.txt.

Your output should look like:

There are 6 values in the file

The maximum value is 9.500000

The minimum value is 1.100000

and this is maxminin.txt:

8.2
1.1
3.7
2.2
9.5
4.3

Answer 1

MaxMin.cpp

#include <iostream>
#include<fstream>
#include<cfloat>
using namespace std;

int main()
{
ifstream inputFile;
inputFile.open("maxminin.txt");
double max = DBL_MIN, min =DBL_MAX;
int numbersCount = 0;
double eachValue = 0;
if (inputFile.is_open()) {
while (!inputFile.eof()) {
numbersCount++;

inputFile >> eachValue;
if(max < eachValue){
max = eachValue;
}
if(min > eachValue){
min = eachValue;
}

}
}
cout<<"There are "<<numbersCount<<" values in the file"<<endl;
cout<<"The maximum value is "<<max<<endl;
cout<<"The minimum value is "<<min<<endl;
inputFile.close();

return 0;
}

Output:

sh-4.3$ g++ -std-c++11 -o main*.cpp sh-4.3$ main There are 6 values in the file The maximum value is 9.5 The minimum value is 1.1
