使用来自float.h和limits的数据，找到该系统的一些数字限制

#include <stdio.h>
#include <limits.h>    // integer limits
#include <float.h>     // floating-point limits

int main(void){    
    printf("Biggest int: %d/n", INT_MAX);
    printf("Smallest long long: %lld/n", LLONG_MIN);
    printf("One byte = %d bits on this system./n", CHAR_BIT);
    printf("Largest double: %e/n", DBL_MAX);
    printf("Smallest normal float: %e/n", FLT_MIN);
    printf("float precision = %d digits/n", FLT_DIG);
    printf("float epsilon = %e/n", FLT_EPSILON);
    return 0;
}
