Reading a file and storing in a buffer.

C++

Hi Guys,

I am reading a file using fstream,
and storing the contents in a char buffer.
its size is 1200 bytes.
i want to write that buffer into a temp file by deleting contents and appending some bytes to the temp file.
example below

for(i=0;i<buffesize;i++)>
{
if i>200 && i<205) continue; 
// here it skips the 4bytes.i want to append in same position which existing should
// not print
tempfile<<buffer[i];
}

before writing into a file i want to delete 4bytes in a 200th position and append 8 bytes in the same poistion.

can anyone help in this regard


thanks
