SUP!, well i need help, im using visual C++, and i need to write a simple program that reads 100 numbers from 1 to 100 on a txt file, calculates their average, and the standard deviation and then inputs the standard deviation and average into the original file at the bottom:? .....k i know you start off with the basic library's you'll be using and the basic setup and such,, but from there on i am completely lost8O ,........be great if someone could help me writing this out so i can understand what i should be doing..shouldn't take long since i was peeping the forum and people seem C++ savy here...
btw the file im using is called data.txt...and is in the "Temp" folder of my c drive...THIS is attempt so far ....keep in mind im mad beginner ...in essence i need help in the whole std deviation part.
THANKS!
btw this is my code so far, be great if someone could tell me if im ok so far, aslo how i could do the standard deviation, i cant find a way to do it..
Code:
#include <iostream>
#include <cmath>
#include <fstream>
#include <iomanip>
using namespace std;
int main()
{
float sum = 0, StdDev = 0;
int x = 0;
ifstream inFile;
inFile.open("data.txt");
while ( inFile >> x )
{
sum += x;
}
inFile.close();
ofstream outFile( "data.txt", ios::app );
outFile.seekp( ios::end );
outFile << sum << endl;
outFile.close();
return 0;
}
