今日完成《Programming Abstractions In C》阅读P69-p71。
一、技术总结
涉及到的技术知识点有“symbolic constant”,”Array declaration”，“Array selection”。

#include <stdio.h>
#define  NJudges 5

int main(int argc, char const *argv[])
{
    // Array declaration p69: type name[size];
    double scores[NJudges]; // 为了方便后续修改，所以数组的大小声明为symbolic constant

    // Array selection p70: array[index]
    scores[0] = 9.2;
    scores[0] = 9.9;
    scores[0] = 9.7;
    scores[0] = 9.0;
    scores[0] = 9.5;

    return 0;
}

二、英语总结
1、 pictorially
pictorial > pictorially：pictorius(of a painter) + -al(of, like, related to pertain to)。所以，pictorially的意思是in a way that related to pictures or photographs(图像化地，以绘画的方式)。
2、 gymnastics
phicical exercise that increase th body’s strength, balance and ability to move gracefully(体操)。
3、 figure skating
a type of skating that involves circular patterns and often includes jumps(花样滑冰)。
4、 effective size
effective 在这里的意思是：in fact，所以 effective size的意思是“实际大小”，“有效大小”。
