Reading in a ile of data points using multidimensional array Read the coordinate values of the location of the mass and the value of the mass from Calculate the center of mass Formula e Center of mass in x direction Center of mass in y direction = Center of mass in z direction %1(mi) 2i1(m) File would be formatted in a similar fashion (x,y,z) mass (2,4,8) 20 (12,7,16) 30 (23,40,12) 12

Explanation / Answer

#include<iostream.h>

#include<conio.h>

#include<fstream.h>

#include<ctype.h>

#include<stdlib.h>

void main()

{

ifstream file1("data.txt");

char a[100][4]; char ch; int i=0,j=0;

clrscr();

while(!file1.eof())

{

file1>>ch;

if(isdigit(ch))

a[i][j++]=ch;

if(j>3)

{ i++; j=0;}

}//while

int n1=0,n2=0,x=0,y=0,z=0,mass=0;

for(n1=0;n1<=i;n1++)

{

x+=a[n1][0];

y+=a[n1][1];

z+=a[n1][2];

mass+=a[n1][3];

}

double massx=x/mass;

double massy=y/mass;

double massz=z/mass;

cout<<" center of mass in X Direction ="<<massx;

cout<<" center of mass in Y Direction ="<<massy;

cout<<" center of mass in Z Direction ="<<massz;

getch();

}
