Question

PLease code a C++ program that prompts a user to enter 10 numbers. this program should read the numbers into an array and find the smallest number in the list, the largest numbers in the list the sum of the 10 numbers and the average of the 10 numbers please use file i/o and input measures for Handling Errors in C++ When Opening a File

Answer 1

Code:

#include <iostream>

#include <iomanip>

#include <fstream>

using namespace std;

int main() {

float numbers[10],sum = 0,smallest,largest,average,x;

ifstream inFile;

int i=0;

inFile.open("test.txt"); //open input file

if (!inFile) {

cout << "Unable to open file"; //if file will not open

exit(1); // terminate with error

}

else //if file sucessfully open

{

while (inFile >> x) //read 10 numbers from file and store in array

numbers[i++]=x;

}

smallest=numbers[0]; //Consider first element as smallest

largest=numbers[0]; //Consider first element as largest

for(i=0;i<10;i++)

{

sum=sum+numbers[i]; //calculate sum of the numbers

if (numbers[i] < smallest) //find smallest number

smallest = numbers[i];

if (numbers[i] > largest) //find largest number

largest = numbers[i];

}

average=sum/10; //calculate average

inFile.close(); //close the input file

//print outputs

cout << "Smallest number = " << smallest << endl;

cout << "Largest number = " << largest << endl;

cout << "Sum = " << sum << endl;

cout << "Average = " << average << endl;

return 0;

}
