How can I send those values to the addData() function using two functions as shown above.

string getName( void )
{
}
 
char getGender( void )
{
}
...
addData(getName(), getGender());

second question is that can you provide me the stuff: for example: %d,if%, and so forth

int i= 100;
float f = 3.14159;
printf("An integer, i=%d, a float f=%f\n", i, f);

where can i find ofs.write() and ofs.read() function explanation? thanks

int i, j, k;
double a[10][3][4];

for (i=0; i<10; i++)
  for (j=0; j<3; j++)
    for (k=0; k<4; k++)
      a[i][j][k] = (double)rand()/RAND_MAX;

FILE * fp = fopen("arrays.bin","wb");
fwrite(a, sizeof(double), 10 * 3 * 4, fp);
fclose(fp);

double b[10][3][4];
FILE * fp = fopen("arrays.bin","rb");
fread(b, sizeof(double), 10 * 3 * 4, fp);
fclose(fp);
// now b contains the same values the original arrays have.

double c[3][4]; // we want to initialise c with the values of the original a[6] array
FILE * fp = fopen("arrays.bin","rb");
fseek(fp, sizeof(double) * 6 * 4 * 3, SEEK_SET); 
fread(c, sizeof(double), 3 * 4, fp);
fclose(fp);

cout <<" "<<a[i][j][0]<<" "<<a[i][j][1]<<" "<<a[i][j][2]<<" "<<a[i][j][3];
cout << endl;
}
}

but however i couldn't get solution, for example,
a[5]
display 3x4 array
