Learn point C language (12): Data type

C Language Data type: Basic type, constructed type, pointer type, empty type.

Basic types include: integer, character, floating-point (single, double), enumeration.

The constructed types also include: arrays, structs, and common bodies.

1. Display the minimum and maximum values of int:

#include　<stdio.h>
#include　<limits.h>

int　main(void)
{
　　int　n1,n2;

　　n1　=　INT_MIN;
　　n2　=　INT_MAX;
　　printf("%d　..　%d",　n1,n2);

　　getchar();
　　return　0;
}

2. Display the minimum and maximum values for single precision type (float):

#include　<stdio.h>
#include　<float.h>

int　main(void)
{
　　float　f1　=　FLT_MIN;
　　float　f2　=　FLT_MAX;

　　printf("%e　..　%e\n",　f1,f2);

　　getchar();
　　return　0;
}

3. Display minimum and maximum values for double:

#include　<stdio.h>
#include　<float.h>

int　main(void)
{
　　double　d1　=　DBL_MIN;
　　double　d2　=　DBL_MAX;

　　printf("%e　..　%e\n",　d1,d2);

　　getchar();
　　return　0;
}
