My inFile will be something like this
6
1 2 3 4 5 6
0 1000 1 0 -999 1
-2 1 -3 -1 2 3
-10 -30 -20 -5 -15 -50
so, the first number is the number of numbers in each line.
I have to calculate the ave, min, max and total for each line and outfile it like this;
1 2 3 4 5 6
Min: 1
Max: 6
Ave: 3.5
Total: 21
0 1000 1 0 -999 1
MIn: ....
and so on.
My problem so far is that I cant find out how to inFile the first number into a variable, then input the following numbers of each line into variables, here is what I have so far;
#include%26lt;iostream%26gt;
#include%26lt;cmath%26gt;
#include%26lt;iomanip%26gt;
#include%26lt;fstream%26gt;
using namespace std;
int main ( )
{
int j,i;
ifstream inFile;
ofstream outFile;
inFile.open("inFile.txt");
outFile.open("outFile.txt");
if((inFile.fail())||(outFile.fail()))
cout%26lt;%26lt;"Error: File open failure"%26lt;%26lt;endl;
else
{
do
{
if(j!='\n')
{
inFile%26gt;%26gt;j;
}
for(i=0; i!='\n', i%26lt;=j; i++)
{
inFile%26gt;%26gt;i;
}
cout%26lt;%26lt;setw(50)%26lt;%26lt;i%26lt;%26lt;endl;
cout%26lt;%26lt;j%26lt;%26lt;endl;
}
while(!inFile.eof());
}
return 0;
}
Intro to C++ Problem please help!?
Here is the solution
#include %26lt;iostream%26gt;
#include %26lt;fstream%26gt;
#include %26lt;string%26gt;
#include %26lt;sstream%26gt;
#include %26lt;algorithm%26gt;
using namespace std;
ifstream inFile("inFile.txt");
#define cin inFile
ofstream outFile("outFile.txt");
#define cout outFile
int main()
{
string line;
int n,total,index;
int *elements;
cin%26gt;%26gt;n;
getline(cin,line);
elements=new int [n];
while (getline(cin,line))
{
istringstream ss(line);
index=0;
while (!ss.eof())
ss%26gt;%26gt;elements[index++];
cout%26lt;%26lt;"Min: "%26lt;%26lt;*min_element(elements,elements+n)%26lt;%26lt;en...
cout%26lt;%26lt;"Max: "%26lt;%26lt;*max_element(elements,elements+n)%26lt;%26lt;en...
total=0;
for (int j=0;j%26lt;n;j++)
total+=elements[j];
cout%26lt;%26lt;"Ave: "%26lt;%26lt;(float)total/n%26lt;%26lt;endl;
cout%26lt;%26lt;"Total: "%26lt;%26lt;total%26lt;%26lt;endl%26lt;%26lt;endl;
}
delete []elements;
return 0;
}
hope i helped u
