Question

So I was given a code in class to help with this assignment...Ihave modified it a bit but I just read the part where I have toprompt the user for a filename....

In the same folder as this C file I have a txt file with the infoneeded...

How can I change this code so I can ask a user for a txt file toread?

#include <stdio.h>

int main()
{

//variables
FILE* pFile = NULL;
int nsid = 0;
char lastname[255];
float midterm = 0;
float final = 0;
float wavg = 0;
char decision = 0;

// r means open for reading can only open for reading nowriting
pFile = fopen("input.txt", "r");
if (pFile == NULL)
{
    printf ("Error opening file! ");
    return -1;
}

printf("%-10s %-10s %-10s %-10s ", "nsid" , "lastname" ,"midterm" , "final");
while (!feof(pFile))
{
    // -10s aligns the columns
    fscanf(pFile, "%d %s %f %f ", &nsid,lastname, &midterm, &final);
   
   
    printf("%-10d %-10s %-10f %-10f ", nsid,lastname, midterm, final);
   
}

   fclose(pFile);

return 0;
}
