I am having several issues with my code to get the expectedoutput for output 3 without messing up my code with output 8. Ihave tried modifying my code several times but it hasn’t workedsuccessfully. I have posted my code, and outputs below. ThankYou.
CODE:
#include
#include
#include
#include
using namespace std;
const int MAX_COLUMNS = 5;
//readFile function reads the input file and populates thearray
int readFile(doublevalues[][MAX_COLUMNS], int maxRows, stringinputFileName)
{
//variable declaration
int i, j;
string line;
//Openin the file
ifstream fin;
fin.open(inputFileName.c_str(),ios::in);
//Check file exists or not
if (fin.fail())
{
//Failed to open file
return -1;
}
else
{
//Read the data
for (i = 0; i
{
for (j = 0; j
{
//Read the value from each row
fin >> values[i][j];
//Return 0 if the file contains no data
if (fin.fail() && i == 0)
{
return 0;
}
}
}
}
//Close the file
fin.close();
//Return the number of rows read
return i;
}
//Avearge function calcuates the average of the array
double average(doublevalues[][MAX_COLUMNS], int numberRows)
{
double sum = 0;
int i, j;
//Iterate over rows
for (i = 0; i
{
//Iterate over columns
for (j = 0; j
{
//Calculate the sum
sum = sum + values[i][j];
}
}
//Find the avearge and return it
return (sum /(double)(numberRows*MAX_COLUMNS));
}
//columnAverage function calculates the average of eachcolumn
double columnAverage(doublevalues[][MAX_COLUMNS], int column,int numberRows)
{
double sum = 0;
int i;
//Iterate over rows
for (i = 0; i
{
//Calculate the sum
sum += values[i][column];
}
//Find the avearge and return it
return (sum /(double)(numberRows));
}
//smallestValue function returns the smallest value in eachrow
double smallestValue(doublevalues[][MAX_COLUMNS], int rowNumber)
{
double minVal = values[rowNumber][0];
int i;
//Iterate over columns
for (i = 0; i
{
//Calculate the sum
if (values[rowNumber][i] < minVal)
{
//Update the minimum value
minVal = values[rowNumber][i];
}
}
//Return min value
return minVal;
}
//Main function
int main()
{
int rows, cols;
const int MAX_ROWS = 30;
string inputFileName;
double grades[MAX_ROWS][MAX_COLUMNS];
int actualRows;
//Set to two decimal places
cout << fixed << setprecision(2);
//Read file name
cout << “Enter input file name “;
cin >> inputFileName;
//Read data from file
actualRows = readFile(grades, MAX_ROWS, inputFileName);
//Check number of rows
if (actualRows == -1)
{
//Print error message
cout << endl << “File “” << inputFileName<< “” could not be opened ” << endl;
}
else if (actualRows == 0)
{
//Print error message
cout << endl << “The input file “” <<inputFileName << “” did not contain any data ” <<endl;
}
else
{
cout << “nProcessing ” << actualRows << “rows, and ” << MAX_COLUMNS << ” columns ” <<endl;
//Print average value
cout << “Average for all values is ” <<average(grades, actualRows) << endl;
//Print column wise average
for (cols = 0; cols < MAX_COLUMNS;cols++)
{
//Print column wise average
cout << “Average for column ” << cols << ” is” << columnAverage(grades, cols, actualRows) <<endl;
}
//Print row wise smallest value
for (rows = 0; rows < actualRows;rows++)
{
//Print row wise smallest value
cout << “Smallest value for row ” << rows << “is ” << smallestValue(grades, rows) << endl;
}
}
return 0;
}
For output 8 I get it correct but my other output 3 above getsproblems due to that but if I modify my code for it to work onoutput 3 (above) it will make my output 8 incorrect. I am justhaving trouble on making both outputs correct at the same time.
