整型int可添加short和long:
short int:簡為short;
long int: 簡為long;
long long int: 簡為long long
它們都可以再添加 unsigned:
unsigned int: 簡為unsigned
unsigned short int: 簡為unsigned short
unsigned long int: 簡為unsigned long
unsigned long long int: 簡為unsigned long long
char 可添加 unsigned:
unsigned char
double 可添加 long:
long double
1. short 的最小、最大值:
#include <stdio.h>
#include <limits.h>
int main(void)
{
short n1 = SHRT_MIN;
short n2 = SHRT_MAX;
printf("%d .. %d\n", n1,n2);
getchar();
return 0;
}
2. long 的最小、最大值:
#include <stdio.h>
#include <limits.h>
int main(void)
{
long n1 = LONG_MIN;
long n2 = LONG_MAX;
printf("%ld .. %ld\n", n1,n2);
getchar();
return 0;
}
3. long long 的最小、最大值:
#include <stdio.h>
#include <limits.h>
int main(void)
{
long long n1 = LLONG_MIN;
long long n2 = LLONG_MAX;
printf("%lld .. %lld\n", n1,n2);
getchar();
return 0;
}
4. unsigned 系列的最小值都是 0:
#include <stdio.h>
#include <limits.h>
int main(void)
{
unsigned short n1 = USHRT_MAX;
unsigned n2 = UINT_MAX;
unsigned long n3 = ULONG_MAX;
unsigned long long n4 = ULLONG_MAX;
unsigned char c = UCHAR_MAX;
printf("0 .. %u\n", n1);
printf("0 .. %u\n", n2);
printf("0 .. %lu\n", n3);
printf("0 .. %llu\n", n4);
printf("\n0 .. %u\n", c);
getchar();
return 0;
}
5. long double 的最小、最大值:
#include <stdio.h>
#include <float.h>
int main(void)
{
long double ld1 = LDBL_MIN;
long double ld2 = LDBL_MAX;
printf("%Le .. %Le\n", ld1,ld2);
getchar();
return 0;
}
