FILE *fp;

char any[8];

 

cout << "Enter a file name\n";

cin >> any;

 

fp = fopen(any,"wb");

    for(j=0;j<50;j++)

    {

       for(i=0;i<200;i++)

                   k = rand() % RAND_MAX;

                   fwrite(&k,sizeof(int),1,fp);

       }

    }

/*fclose(fp);

 

fp = fopen(any,"rb");   */

    i = 0;

    while (fread(&l,sizeof(int),1,fp) != 0)

    {

                  list[i] = l;

                  i = i + 1;

    }

fclose(fp);

 

for (i=0;i<50;i++)

    cout << list[i] << '\n';

 

/*for(i=0;i<900;i++)
