首先:
编程思维 ==》想法 == 》目标(需要规划) ==》面向过程
将大目标变成小目标。
举一个扑克牌游戏的例子:
1. 程序中储存一副牌 2.洗牌3发牌
一.程序中储存一副牌
用什么存 (全局变量)
多大 (54)
怎么表达牌
1、 数字
2、 花色 几种 (4种)
Int Char g_card[54]
Int Char g_colour[54]
设定本地语言切换代码页
用法 setlocal(LC_ALL , ” 语言 ”) 或者setlocal(LC_ALL , ” . 代码页 ”)
二、洗牌
1、洗谁 ? Int Char g_card[54]Int Char g_colour[54]
2、怎么洗
1、算法选择(乱牌)
2、随机一个数(下标1-53)
3、交换数据
//随机种子的初始化 srand((unsigned)time(NULL));
3、发牌
三个玩家
1、怎么表达玩家
2、每个玩家几张牌
Char player_card[3][20]
Char player_colour[3][20]
怎么发牌
1、一张一张的发。发完第一圈后重复17次
排序玩家牌面
一、冒泡排序
1、后面如果有比第一个数字大的就和第一个交换
2、后面如果有比第二个数字大的就和第二个交换
3、···········
[0]3 [1] 2 [2] 1 [3] 4 [4]5 [5]6
[0] 1 [1] 2 [2] 3 [3] 4 [4]5 [5]6
二、选择排序
[0]3 [1] 2 [2] 1 [3] 4 [4]5 [5]6
[2] 3 [1] 2 [0] 1 [3] 4 [4]5 [5]6
(结尾附上以前写的代码)
问题:绘制菱形
6 * 将他看成数学的平面图,求二元一次方程解
5 * * y = - x + 3
4 * * y = - x + 9
3 * * y = x + 3
2 * * y = x + -3
1 * *
0 *
0 1 2 3 4 5 6
for(y = 0;y < 7; y++) { for(i = 0 ;i < 7 ; i++) { if(y = - x + 3||y = - x + 9||y = x + 3||y = x + -3) { printf(“* ”); } else { printf(“ ”); } }
两个早期的bug
go to现阶段仅使用多重循环跳出或者低级语言模拟,其他情况不允许使用。
低版本bug
foo() { goto NEXT; return 0; NEXT ; }
死循环 NEXT: goto NEXT;
float f scanf(“%f”,&f);
系统蹦了
环境浮点初始化麻烦
如果没有浮点运算,就没有初期化浮点环境。Scanf相当于用了浮点运算,所以系统崩溃。
