Programming languages (e.g. c, c++, and java) usually have several types for integer arithmetic: signed and unsigned types types of different size: short , int , long , long long types of guaranteed and non guaranteed (i.e.implementation dependent) size: e.g. int32_t vs int (and I know that int32_t is not part of the language) How would you summarize when one should use each of them?

When to use different integer types?

Programming languages (e.g. c, c++, and java) usually have several types for integer arithmetic:

signed and unsigned types
types of different size: short, int, long, long long
types of guaranteed and non guaranteed (i.e.implementation dependent) size:
e.g. int32_t vs int (and I know that int32_t is not part of the language)

How would you summarize when one should use each of them?
