Thread: Passing Structs Into An Array Of Structs.

Here I have a C program that is supposed to pass structs that it reads from a .csv file to get the fields for the individual structs. Then it should pass the filled struct into the array. But it's not putting the information in the right slots in the array. I'm pretty new to C. I generally work with C#. So I'm not used to pointers and addresses and the like. I might have done something wrong there. If someone can point me in the right direction that would be great!

Thanks!

Code:

#include <stdio.h>
#include <stdlib.h>
#include <fcntl.h>
#include <string.h>


typedef struct {
    //COUNTRY ID, COUNTRY NAME, POPULATION, LIFE EXPECTANCY, AND DATE OF FOUNDING
    char *id;
    char *name;
    int population;
    float lifeExpectancy;
    int year;
}CountryData;
CountryData FormatData(char *data);
int main()
{
    int         fr                      =   open("SampleCountriesInput.csv", O_RDONLY);
    int         inputSize               =   200;
    int         i                       =   0;
    int         j                       =   0;
    char        line[inputSize];
    char        buff[1];
    ssize_t     n;
    CountryData countries[50];
    CountryData country;
    do
    {
        n = read(fr,buff,1);
        if(buff[0] == '\n')
        {
            country = FormatData(line);
            //countries[j] = FormatData(line);
            strncpy(&countries[j].id, &country.id,3);
            strncpy(&countries[j].name, &country.name, 18);
            countries[j].population = country.population;
            countries[j].year = country.year;
            countries[j].lifeExpectancy = country.lifeExpectancy;
            j++;
            i=0;
        }
        else
            line[i] = buff[0];
        i++;
    }while( n != 0);
    j--;
    while(j!=0)
    {
        printf(countries[j].name);
        j--;
    }
    return 0;
}

CountryData FormatData(char *data)
{
    CountryData country;
    char *token[20];
    int j, i = 0;
    token[0] = strtok(data, ",");
    while(token[i] != NULL)
    {
        i++;
        token[i] = strtok(NULL, ",");
    }
    country.id = token[1];
    country.name = token[2];
    country.lifeExpectancy = atof(token[8]);
    country.population = atoi(token[7]);
