关于swich语句求助大神们

[newcomer_mz]

大神们帮帮忙啊 、、、%>_<%
程序老是 出错或者得不到想要的，程序主体没错，我其实就是想用switch语句编辑一个菜单方便我输入数字1 2 后就可以得到
我想要的。其实就是使用菜单选择操作，提示用户进行相应操作， 但是我的swich语句 用的不对劲额。。。程序主体的求解部分没有错误（这个单独试过）关键是SWICH语句的使用
各位教教我哈~十分感谢。。最好教我怎么用，简略点帮我改改~O(∩_∩)O谢谢
#include<stdio.h>

教你一个方法，case呢，对应一个函数，把你那么长的代码都放到函数里实现，代码好看又容易检查

[xiaoboalex]

case1 --> case 1
caes2 --> case 2

#include<stdio.h> 
int score[4][4],choose; 
void main() 
{
	printf("welcome to my design !my c is who run the least fast \n");
	printf("if you want to go the program without thinking ,please put into 1\n");
	printf("if you wan to go over slightly, please put into 2\n ");
	scanf("%d",&choose);//你没读入选择啊
	switch(choose)
	{
	case 1://case和1要有个空格
		{
			int i,j,k,who; 
			score[1][1]=7; 
			score[2][1]=8; 
			score[3][1]=9; 
			for(i=1;i<=3;i++)

scanf("%d",&choose);//1.
switch(choose)
{
case1:{int i,j,k,who;
score[1][1]=7;
...

[xiaoboalex]

在switch(choose)之前添加scanf("%d", &choose);

[huanmie_09]

没有看你逻辑的处理，switch语句case分支后，如果你想处理完后就跳出switch,就在每个case后面添加一个break;

#include<stdio.h> 

int score[4][4],choose; 

void main() 
{ 
	printf("welcome to my design !my c is who run the least fast \n");
	printf("if you want to go the program without thinking ,please put into 1\n");
	printf("if you wan to go over slightly, please put into 2\n ");
	switch(choose) {
		case1: {
			int i,j,k,who; 
			score[1][1]=7; 
			score[2][1]=8; 
			score[3][1]=9; 
			for(i=1;i<=3;i++) 
				for(j=1;j<=3;j++) 
					for(k=1;i!=j&&k<=3;k++) 
						if(k!=i&&k!=j&&15-i-score[1][1]!=15-j-score[2][1] 
							&&15-i-score[1][1]!=15-k-score[3][1] 
							&&15-j-score[2][1]!=15-k-score[3][1]
							&&15-i-score[1][1]!=i+1
							&&15-j-score[2][1]!=j+1
							&&15-k-score[2][1]!=k+1) 
						{ 
							score[1][2]=i;
							score[1][3]=15-i-7; 
							score[2][2]=j;
							score[2][3]=15-j-8; 
							score[3][2]=k;
							score[3][3]=15-k-9; 
						} 
			for(who=0,i=1;i<=3;i++,printf("\n")) 
				for(j=1;j<=3;j++) { 	
					printf("%d",score[i][j]); 
					if(score[i][j]==1)
						who=i; 
				} 
			if(who==1) 
				printf("The last one arrived to end is a child from family Zhang.\n"); 
			else if(who==2) 
				printf("The last one arrived to end is a child from family Wang.\n"); 
			else 
				printf("The last one arrived to end is a child from family Li.\n");
			break;  /*添加break*/
		} 
		caes2:
			printf("the program is over, thank you for your fitting\n");
			break;    /*添加break*/
		default:break; 
	}
}

没有输入choose变量，因为定义的是全局变量，因此会初始化为0.
如果要接受输入，可以在switch语句前面添加scanf("%d", choose);

谢谢各位大神额。。代码好了 谢谢！O(∩_∩)O~

单步调试和设断点调试是程序员必须掌握的技能之一。
