    #include <stdio.h>
    #include <stdlib.h>
    #include <string.h>
    #define NUM_LINE 21
    
    typedef struct
    {
    	char states[100];
    	char cities[100];
    	int tempt;
    } INFO;
    void getData(FILE *spData, INFO list[]);  
    void insertionSort(INFO list[], int last);
    
    int main (void)
    {
    
    // Local Declarations
    
    FILE *spData = fopen("in.txt", "r");
    INFO list[NUM_LINE];
    
    
    // Statements
    getData(spData, list);
    
    return 0;
    }
    
    /*========================== getData========================
    Pre: FILE *spData
    Post: FILE *spData 
    */
    // Local Declarations
    int i;  
    
    void getData(FILE *spData, INFO list[NUM_LINE])
    {
    	if((spData = fopen("in.text", "r")) = NULL)
            printf("Error openning in.txt\n");
     
    for (i = 0; i < NUM_LINE; i++)
    fscanf(spData,"%s %s %d", list->states, list->cities, list->tempt );

    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.
