Hi,I'm really new programming in C++ and I need your help.
I have to make a program which has to read from a .dat file a column of 9999 values (like 6548.098976) and from this file find the maximun, minimun and later on make an histogram with 90 intervals.
I have some problems because it read the data but it doesn't find the maximun and minimun, it write 57 for both.
On the other hand, I don't have any idea of how to draw an histogram. It should be something like this:
http://maps4twan.blo.../histogram.html
Here it's my attempt,
#include <iostream> #include <fstream> using namespace std; ifstream::pos_type size; char * memblock; int main () { int n, i, result=0; ifstream file ("data.dat", ios::in|ios::binary|ios::ate); if (file.is_open()) { size = file.tellg(); memblock = new char [size]; file.seekg (0, ios::beg); file.read (memblock, size); file.close(); cout << "the complete file content is in memory"; cout << memblock; for (i=0;i<9999;i++) { if (memblock[i]>result) result=memblock[i]; } cout<<"max numb is:"<<result; for (n=0;n<9999;n++) { if (memblock[n]<result) result=memblock[n]; } cout<<"min numb is:"<<result; } else cout << "Unable to open file"; return 0; }
Thanks

Your memblock is type char. You indicated in your original post that your expected data is floating point. If your .dat file is binary, you'll have to do some casting of data. If your .dat file is actually a text file, then you'll have to do some parsing of data.

Hi Skydiver,
As I said I'm a noob, so I don't know what I have to change to obtain a result. The .dat file is binary not text file so I think I have to put float instead of char, but I find a lot of compilation errors and I don't know what is the mistake if you could help me I will be very grateful.
Thanks
