Hey guys, I managed to write a program that woudl read in an .ASE file (its a file that 3d studio max can export about a model, and its an ascii file). But since it's an ascii file, its pretty large. So i wanted to resave all the data to a data file. But i kept having problems reading the data once I wrote it to the file. I coudln't figure out what was wrong, so I wrote a smaller program to just write 750,000 floating point numbers to a file, and then read them back in. And i'm having the same problem I did before, It will write all the data out, but it won't read them all in. here's the entire code:

#include <stdio.h>
#include <stdlib.h>
#include <time.h>

float* read(char* location){
     FILE* mFile = fopen(location, "r");     
     float * numbers;
     
     
     numbers = new float[750000];
     
     if(numbers == NULL){
            printf("not enough memory\n");
            system("PAUSE");
     }
     
     printf("Number's read: %d\n\n", fread(numbers,  sizeof(float), 750000, mFile));     
     system("PAUSE");
     
     fclose(mFile);       
     
     return(numbers);
}

void write(float * numbers, char* location){
     
     FILE* mFile = fopen(location, "w");
     
     printf("wrote %d numbers\n", fwrite(numbers, sizeof(float), 750000, mFile));
     fclose(mFile);
}


int main(int argc, char *argv[])
{    
    float * numbers;    
    srand( time(NULL));
    
    numbers = new float[750000];
    
    for(int x=0;x<750000;x++){
            numbers[x] = (float) ((rand()%RAND_MAX))/RAND_MAX * 1000;
    }
    
    write(numbers, "test.txt");     //write the numbers to the data file
    delete[] numbers;


    numbers = read("test.txt");    //read the numbers back in
    delete[] numbers;
    
    system("PAUSE");
    return EXIT_SUCCESS;
}

I hope someone can tell me what i'm doing wrong, I've spent almost 5 hours trying to get this read/write working :( Thanks Gavin

Have yout tried writing say 10 numbers to the file (something readable) to verify that they are all being written correctly?

Holy crap Rpg_code_master. I LOVE YOU SO MUCH.

It worked. I've been pulling my hair out over this.

Thank's so much.

Yes, I did test it with smaller numbers, and it did work properly with smaller numbers (between 20-70 float values), but when i had more than that, it would mess up.
