c语言整数和浮点数的最大最小值 。
代码如下：
#include <stdio.h>
#include <limits.h>
#include <float.h>
int main()
{
printf(“CHAR_MIN = %d\n”, CHAR_MIN);
printf(“CHAR_MAX = %d\n”, CHAR_MAX);
printf(“SCHAR_MIN = %d\n”, SCHAR_MIN);
printf(“SCHAR_MAX = %d\n”, SCHAR_MAX);
printf(“UCHAR_MAX = %d\n”, UCHAR_MAX);
printf(“CHAR_BIT = %d\n”, CHAR_BIT);
printf(“SHRT_MIN = %d\n”, SHRT_MIN);
printf(“SHRT_MAX = %d\n”, SHRT_MAX);
printf(“USHRT_MAX = %d\n”, USHRT_MAX);
printf(“INT_MIN = %d\n”, INT_MIN);
printf(“INT_MAX = %d\n”, INT_MAX);
printf(“UINT_MAX = %u\n”, UINT_MAX);
printf(“LONG_MIN = %d\n”, LONG_MIN);
printf(“LONG_MAX = %d\n”, LONG_MAX);
printf(“ULONG_MAX = %u\n”, ULONG_MAX);
printf(“FLT_MIN = %g\n”, FLT_MIN);
printf(“FLT_MAX = %g\n”, FLT_MAX);
printf(“DBL_MIN = %g\n”, DBL_MIN);
printf(“DBL_MAX = %g\n”, DBL_MAX);
printf(“LDBL_MIN = %g\n”, LDBL_MIN);
printf(“LDBL_MAX = %g\n”, LDBL_MAX);
return 0;
}
运行如下：
CHAR_MIN = -128
CHAR_MAX = 127
SCHAR_MIN = -128
SCHAR_MAX = 127
UCHAR_MAX = 255
CHAR_BIT = 8
SHRT_MIN = -32768
SHRT_MAX = 32767
USHRT_MAX = 65535
INT_MIN = -2147483648
INT_MAX = 2147483647
UINT_MAX = 4294967295
LONG_MIN = -2147483648
LONG_MAX = 2147483647
ULONG_MAX = 4294967295
FLT_MIN = 1.17549e-038
FLT_MAX = 3.40282e+038
DBL_MIN = 2.22507e-308
DBL_MAX = 1.79769e+308
LDBL_MIN = 2.22507e-308
LDBL_MAX = 1.79769e+308
请按任意键继续. . .
可以看出，long其实就是int，long double其实就是double。
