Question

How would I change this program to create a struct for the three arrays of x, y, and z. Then create an array from that struct?



#include <stdio.h> #include <math.h> #define MAX 4.0 #define MIN 2.0 int main(void) {
FILE *inFile; //read file
inFile = fopen("ATOMS.DAT", "r"); //open file
//declare variable char line[100]; int n = 0; int id = 0; double dis = 0; int cnt = 0; double sum = 0; double avg = 0; fscanf(inFile, "%d", &n);
//create arrays for all x, y, and z coordinates double x[n]; double y[n]; double z[n]; //skip comments fscanf(inFile, "%s", line); fscanf(inFile, "%s", line);
for (int i = 0; i < n; i++) { //read file line by line and assign to variables fscanf(inFile, "%d", &id); fscanf(inFile, "%lf", &x[i]); fscanf(inFile, "%lf", &y[i]); fscanf(inFile, "%lf", &z[i]);
} for (int i = 0; i < n; i++) { //for loop for (int j = i + 1; j < n; j++) { //distance between i and j dis = sqrt( pow(x[i] - x[j], 2) + pow(y[i] - y[j], 2) + pow(z[i] - z[j], 2));// distance formula
//check dis in range or not if (dis >= MIN && dis <= MAX) { sum = sum + dis;
//increment the count cnt++;
}
} }
//calculate the avg avg = sum / cnt; //display printf("The average of distances in range is %lf", avg); }

Explanation / Answer

According to your problem code is below but there are some points

-: for access the array x,y,z(member of array) we use the dot(.) opretor

-: size of array x,y,z we can't decide so i take 100000. you can take size of x,y,z according to your problem

-: i don't have your file ("ATOMS.DAT") so it is not possible to run your program and attach output.

c code

#include <stdio.h>

#include <math.h>

#define MAX 4.0

#define MIN 2.0

int n;

struct coordinate//structure of array x,y,z;

{

double x[100];

double y[100];

double z[100];

};

int main(void) {

FILE *inFile; //read file

  

inFile = fopen("ATOMS.DAT", "r"); //open file

//declare variable

char line[100];

int n = 0;

int id = 0;

double dis = 0;

int cnt = 0;

double sum = 0;

double avg = 0;

fscanf(inFile, "%d", &n);

struct coordinate arr[n];//declare the array of structure coordinate

//create arrays for all x, y, and z coordinates

//double x[n];

//double y[n];

//double z[n];

//skip comments

fscanf(inFile, "%s", line);

fscanf(inFile, "%s", line);

for (int i = 0; i < n; i++) { //read file line by line and assign to variables

fscanf(inFile, "%d", &id);

fscanf(inFile, "%lf", &(arr[i].x[i]));//array x,y,z are the members of structure

fscanf(inFile, "%lf", &(arr[i].y[i]));//so for take input we use dot(.) opretor

fscanf(inFile, "%lf", &(arr[i].z[i]));

}

for (int i = 0; i < n; i++) { //for loop

for (int j = i + 1; j < n; j++) {

//distance between i and j

dis = sqrt(

pow(arr[i].x[i] - arr[j].x[j], 2) + pow(arr[i].y[i] - arr[j].y[j], 2)

+ pow(arr[i].z[i] - arr[j].z[j], 2));// distance formula

//check dis in range or not

if (dis >= MIN && dis <= MAX) {

sum = sum + dis;

//increment the count

cnt++;

}

}

}

//calculate the avg

avg = sum / cnt;

//display

printf("The average of distances in range is %lf", avg);

}

if you got my point then please like otherwise comment
