I am trying to use selection sort to sort the list in descending order and I have been on it , just having absolutely no progress. I don't know what to do anymore! This is my latest trial
// Practice working with structs // Practice applying sorting algorithms
#include "cs50.h" #include <stdio.h>
#define NUM_CITIES 10
typedef struct { string city; int temp; } avg_temp;
avg_temp temps[NUM_CITIES];
void sort_cities(void);
int main(void) { temps[0].city = "Austin"; temps[0].temp = 97;
temps[1].city = "Boston";
temps[1].temp = 82;
temps[2].city = "Chicago";
temps[2].temp = 85;
temps[3].city = "Denver";
temps[3].temp = 90;
temps[4].city = "Las Vegas";
temps[4].temp = 105;
temps[5].city = "Los Angeles";
temps[5].temp = 82;
temps[6].city = "Miami";
temps[6].temp = 97;
temps[7].city = "New York";
temps[7].temp = 85;
temps[8].city = "Phoenix";
temps[8].temp = 107;
temps[9].city = "San Francisco";
temps[9].temp = 66;
sort_cities();
printf("\nAverage July Temperatures by City\n\n");
for (int i = 0; i < NUM_CITIES; i++)
{
printf("%s: %i\n", temps[i].city, temps[i].temp);
}
}
// TODO: Sort cities by temperature in descending order void sort_cities(void) { for(int i =0; i < temps[NUM_CITIES]; i++) { for(int j = i+1; j < temps[i]; j++) { if(temps[NUM_CITIES].temp > temps[i]) { temps[NUM_CITIES].temp = temp[i].temp; } } }
}
