In the C programming language, 'int' is a data type that represents signed integers. Its range can vary slightly depending on the compiler and computer architecture. Generally, standard C compilers adhere to the following rules: - The size of an 'int' type is at least 16 bits (capable of representing values from -32,767 to 32,767). - Typically, the size of an 'int' is 32 bits (allowing for values from -2,147,483,647 to 2,147,483,647). - The upper limit for 'int' can be represented by the constant INT_MAX defined in the <limits.h> header file. - The lower limit can be represented by INT_MIN also defined in <limits.h>. Additionally, there are other integer types such as short, long and long long which may have different sizes and ranges compared to 'int'. To ensure code portability when specific integer range requirements exist, fixed-size integer types defined in <stdint.h> (like int16_t or int32_t) should be used. In summary, according to standard specifications, the range for 'int' is at least from -32,767 to 32,767 and typically from -2,147,483,647 to 2,147-483-647.
