In C language, the maximum and minimum values of integer types can be used directly through the header file limits.h in the C standard library. Examples are as follows:
# Contains? & ltstdio.h & gt
# Contains? & lt restrictions & gt
int？ Master ()
{
Printf("char range: %d~%d\n "，CHAR_MIN，？ CHAR_MAX？ );
Printf ("unsigned? Character value range: %u~%u\n ",0,? UCHAR _ MAX)；
Printf("int value range: %d~%d\n ",? INT_MIN，？ INT _ MAX)；
Printf ("unsigned? Int value range: %u~%u\n ",? 0,? UINT _ MAX)；
Return? 0;
