I often see source code using types like uint32, uint64 and I wonder if they should be defined by the programmer in the application code or if they are defined in a standard lib header.
What's the best way to have these types on my application source code?

Int64: This Struct is used to represents 64-bit signed integer. The Int64 can store both types of values including negative and positive between the ranges of -9,223,372,036,854,775,808 to +9, 223,372,036,854,775,807. Example : C#
This type is defined in the C header <stdint. h> which is part of the C++11 standard but not standard in C++03. According to the Wikipedia page on the header, it hasn't shipped with Visual Studio until VS2010. Hope this helps!
The UInt32 value type represents unsigned integers with values ranging from 0 to 4,294,967,295. UInt32 provides methods to compare instances of this type, convert the value of an instance to its String representation, and convert the String representation of a number to an instance of this type.
The C99 stdint.h defines these:
int8_tint16_tint32_tuint8_tuint16_tuint32_tAnd, if the architecture supports them:
int64_tuint64_tThere are various other integer typedefs in stdint.h as well.
If you're stuck without a C99 environment then you should probably supply your own typedefs and use the C99 ones anyway.
The uint32 and uint64 (i.e. without the _t suffix) are probably application specific.

Those integer types are all defined in stdint.h

If you are using C99 just include stdint.h. BTW, the 64bit types are there iff the processor supports them.
