If unable to open it, returns false. Otherwise load the account information from the text file into the integer, double and character arrays and return true at the end. The first char pointer is the string holding the name of the file to open, int * is the account ID array, double * is the amount array, the second char * is the designation array and the last int is the size or the number of records. Use fscanf or other library functions to read in the data.

Explanation / Answer

Please find my implementation of both methods.

Please let me know in case of any issue.

bool load_data(char *file, int *id, double *amt,char *desig, int n){

   int i = 0;

   FILE * fp(file, "r");

   // error check in opening file
   if(fp == NULL){
       return false;
   }

   // trading designation, id and amt in each ineration
   while(i < n){
       fscanf(fp, "%s%d%lf", &desig[i], &id[i], &amt[i]);
       i++;
   }

   fclose(fp); // closing file

   return true;
}

void print_data(int *id, double *amt, char *desig, int n){

   int i;

   for(i=0; i<n; i++){

       printf("%d %.3lf %s ", id[i], amt[i], desig[i]);
   }
}
