send int pointer array to a function and return code example

Example 1: how to create and return a struct array in C

fentry *read_fentries(FILE *fp){
    fentry *files[MAXFILES];

    // EXTRACT FENTRIES AND FNODES FROM FILE
    if ((fread(files, sizeof(fentry), MAXFILES, fp)) == 0) {
        fprintf(stderr, "Error: could not read file entries\n");
        closefs(fp);
        exit(1);
    }
    return files;
}

Example 2: c++ function return array

#include <iostream>
#include <ctime>

using namespace std;

// function to generate and retrun random numbers.
int * getRandom( ) {

   static int  r[10];

   // set the seed
   srand( (unsigned)time( NULL ) );
   
   for (int i = 0; i < 10; ++i) {
      r[i] = rand();
      cout << r[i] << endl;
   }

   return r;
}

// main function to call above defined function.
int main () {

   // a pointer to an int.
   int *p;

   p = getRandom();
   
   for ( int i = 0; i < 10; i++ ) {
      cout << "*(p + " << i << ") : ";
      cout << *(p + i) << endl;
   }

   return 0;
}
