Thread: Looking for help with the array of structures problem :)

I'm trying to input the array of structs into the print_yearly_data function and then loop through the inputted array of structs, printing each individual structures data with the print_climate_data function.

Is there a way to do this using the current methods or do i need to learn something new.

Any help appreciated!

Code:

#include <stdio.h>
#include <string.h>
#include <math.h>


void print_climate_data(struct climatedata a);
void print_yearly_data(struct climatedata b[]);


struct climatedata
{
  char month[10];
  float high;
  float mean;
  float low;
};


int main(void)
{
  int m;


  struct climatedata auck[13];


  strcpy(auck[1].month, "Jan");
  strcpy(auck[2].month, "Feb");
  strcpy(auck[3].month, "Mar");
  strcpy(auck[4].month, "Apr");
  strcpy(auck[5].month, "May");
  strcpy(auck[6].month, "Jun");
  strcpy(auck[7].month, "Jul");
  strcpy(auck[8].month, "Aug");
  strcpy(auck[9].month, "Sep");
  strcpy(auck[10].month, "Oct");
  strcpy(auck[11].month, "Nov");
  strcpy(auck[12].month, "Dec");


  auck[1].high = 30.0f;
  auck[2].high = 30.5f;
  auck[3].high = 29.8f;
  auck[4].high = 26.0f;
  auck[5].high = 24.6f;
  auck[6].high = 23.8f;
  auck[7].high = 19.0f;
  auck[8].high = 20.6f;
  auck[9].high = 22.0f;
  auck[10].high = 23.6f;
  auck[11].high = 25.9f;
  auck[12].high = 28.3f;


  auck[1].low = 5.6f;
  auck[2].low = 8.7f;
  auck[3].low = 6.6f;
  auck[4].low = 3.9f;
  auck[5].low = 0.9f;
  auck[6].low = -1.1f;
  auck[7].low = -3.9f;
  auck[8].low = -1.7f;
  auck[9].low = 1.7f;
  auck[10].low = -0.6f;
  auck[11].low = 4.4f;
  auck[12].low = 7.0f;


  auck[1].mean = 19.1f;
  auck[2].mean = 19.7f;
  auck[3].mean = 18.4f;
  auck[4].mean = 16.1f;
  auck[5].mean = 14.0f;
  auck[6].mean = 11.8f;
  auck[7].mean = 10.9f;
  auck[8].mean = 11.3f;
  auck[9].mean = 12.7f;
  auck[10].mean = 14.2f;
  auck[11].mean = 15.7f;
  auck[12].mean = 17.8f;
  printf("Enter month number: ");
  scanf("%d", &m);


  print_climate_data(auck[m]);






  return 0;
}


void print_climate_data(struct climatedata a)
{
  printf("%s\n", a.month);
  printf("Record High: %.1f C\n", a.high);
  printf("Daily Mean: %.1f C\n", a.mean);
  printf("Record Low: %.1f C\n\n", a.low);


}


void print_yearly_data(struct climatedata b[])
{
  for (int i = 1; i > 13; i++)
  {
    print_climate_data(b[i]);
  }
}

> for (int i = 1; i > 13; i++)
Try < instead.

Other than that, it would seem to be fine.
