Problem with reading of file

Hi all,
I am generating a value by calling some fn which returns uint32_t and storing these values in file. Part of Code as shown below

Code:

//to write content in file
uint32_t c;
ofstream outfile;
	outfile.open("output",ios::app|ios::out|ios::binary);
// putting value in file using loop
outfile<<c;
//to read content of file
ifstream myfile ("output");
	myfile.is_open();
	myfile>>num;  // for first record display
printf("value fetched from file: %.8x\n", num); 

int record = 2* sizeof(uint32_t);     //offset to reach third record
	myfile.seekg( record, ios::beg);
	myfile>>num1;
	printf("value fetched from file: %.8x\n", num1); 
	myfile.close();

the above code gives some garble value. I tried the next code which gives me just the first value and with offset again gives garble values.

Code:

ofstream outfile;
	outfile.open("output");
outfile<<c<<endl;

File "output" contains the value but i am not able to read the value, may be problem with the offset.

It is probably a good idea to open your input file with binary if you wrote it with binary.

Hi
I have refined my code as under but no success so far

Code:

ifstream myfile ("output",ios::in|ios::binary);

You should probably be using the read() and write() member functions when dealing with binary files, as there may not be any separation of the values ,
