I am trying to sort a struct list in C and i get a 0xC0000005 problem. This is the struct i am using:

```
typedef struct Aqi Aqi;
struct Aqi{
int date; // format: yyyymmdd (20200101) - 1st Jan 2020
int time; // Either 9 , 12 or 19
int l1; // l stands for location
int l2;
int l3;
Aqi* next;
};
```

The list is presorted by date and there are three elements for each date (For each given time). So i am using this function to sort the list by times in ascending order:

```
Aqi* sort(Aqi* root){ // I am passing the root of the list
int date;
int tempInt;
int c = 0;
int min;
Aqi* temp = root;
Aqi* temp2 = NULL;
while(temp != NULL){
if(c == 3){ // Counter c is being used to restart values on every 3rd iteration because
c = 0; // that's when the new date starts.
}
if(c == 0){
date = temp->date;
temp2 = temp;
min = temp2->time;
}
while(temp2->date == date){
if(temp2->time < min){
min = temp2->time;
tempInt = temp->time;
temp1->time = min;
temp3->time = tempInt;
tempInt = temp->l1;
temp->l1 = temp2->l1;
temp2->l1 = tempInt;
tempInt = temp->l2;
temp->l2 = temp2->l2;
temp2->l2 = tempInt;
tempInt = temp->l3;
temp->l3 = temp2->l3;
temp2->l3 = tempInt;
}
temp2 = temp2->next;
}
++c;
temp = temp->next;
}
return root;
}
```

The list itself is fine (I can print it with no problem) but the program is having trouble with this function specifically. Why is it giving me an error?
