问题
I am doing some emnedded work for which I am writing program in CPP. My machine has dos platform. In my program I am using long long keyword which is not working.I am using turboC++ 3.2 compiler.
I have searched a lot and find C99 library has stdint.h file but how can i use this file with my compiler. Or some other comiler to work on embedded keywords which made dos based executable file.
回答1:
You are using a platform from the 1980s, before C++ even existed as a standard. Even your int is only 16-bit.
It's not clear what you want to use long long for but if you're after a 64-bit type you're out of luck. Either way, your compiler simply does not support this type. You'll have to come up with a workaround that does not require use of this type.
Or use a compiler from now times.
回答2:
Instead of writing long long, try writing long long int .
Assumption : The error generator echoes that long long is not recognised.
