Help with file I/O in visual C/C++

[bigk376]

Hi,

For class I have to right a console application in visual c/c++ 6.0 that reads a text file stores the text file as an array of integers. Then the program has to perform a bottom-up heap construction on the array. I’ve figured out the bottom-up heap construction and the down heap bubbling. What I haven’t been able to do is figure out how to read this(http://www.utdallas.edu/~besp/CS3345/keys.txt (keys.txt)) txt file into an array of integers, none of the courses I’ve taken so far have covered this, and none of the books I have really show any insight on how to do this. If anyone could show me how to do this or give a hint... I’d really appreciate it.

Thanks,

bigk

Have you written any code yet? If so, it would help if you posted it.

Also, your link is not working.

You need to use the fstream.h library.

Here's some code I got from a program of mine...it should get you started:
ifstream in_file;
int i=0;
char inBuff, buffSize;
in_file.open("inventoryfile.txt");

in_file.getline(inBuff,buffSize);

in_file>>stock[i];

in_file>>price[i];

while(! in_file.eof())
{
i=i+1;
in_file.getline(inBuff,buffSize);

in_file>>stock[i];

in_file>>price[i];

}

in_file.close();
