[Pat]

Hi,

I want to write a int64 data into a file using fprintf(). In the fprintf
argument, which one (%d or %u or other) should be used?

Thanks.

There is no "int64" in C++ so you are using some language extension.
Read the manual for your compiler to find out.

Brief Answer - it depends.
Detailed -
%d - For integers.
%u - For unsigned ints.
%ld - For long.

Having said that, you choose the one , relevant to your application.
