实验1嘿嘿嘿

一、列小人
#include<stdio.h>
int main(){
    printf("0000000000\n"); 
    printf("0  0  0  0\n");
    printf("0    0   0 \n");
    printf("0  00000 0\n");
    printf("0000000000 \n");
    printf("   <  >\n");
    printf("  <    >  \n");
    printf(" < HHH >>>>>>>>> \n");
    printf(" <HHHHHH>  \n  ");
    printf("  <HHH>   \n");
    printf("   I  I  \n ");
    printf("   I  I  \n");
    printf("   III III\n");
    printf("0000000000\n"); 
    printf("0  0  0  0\n");
    printf("0    0   0 \n");
    printf("0  00000 0\n");
    printf("0000000000 \n");
    printf("   <  >\n");
    printf("  <    >  \n");
    printf(" < HHH >>>>>>>>> \n");
    printf(" <HHHHHH>  \n  ");
    printf("  <HHH>   \n");
    printf("   I  I  \n ");
    printf("   I  I  \n");
    printf("   III III\n");
    return 0; 
}
----------------------------------------------------------------------
二、算术1、
#include<stdio.h>
int main(){
    
    int x,y;
    int r1,r2,r3,r4;
    
    x=1;
    y=2;
    
    r1=x+y;
    r2=x-y;
    r3=x*y;
    r4=x/y;
    
    printf("r1=%d\n",r1);
    printf("r2=%d\n",r2);
    printf("r3=%d\n",r3);
    printf("r4=%d\n",r4);
    
    return 0;
    
    
    
    
}
------------------------------------------------------------------------------
三、算术2
#include<stdio.h>
int main(){
    
    float x,y;
    float r1,r2,r3,r4;
    
    x=1;
    y=2;
    
    r1=x+y;
    r2=x-y;
    r3=x*y;
    r4=x/y;
    
    printf("r1=%f\n",r1);
    printf("r2=%f\n",r2);
    printf("r3=%f\n",r3);
    printf("r4=%f\n",r4);
    
    return 0;
    } 
---------------------------------------------------------------------------------
四、算术3
#include<stdio.h>
int main(){
    int n,r1,r2,r3,r4;
    
    n=100;
    
    r1=n*(n+1)/2;
    r2=(n+1)*n/2;
    r3=n/2*(n+1); 
    r4=(n+1)/2*n ; 
    
    printf("n=%d\n",n);
    printf("r1=%d\n",r1);
    printf("r2=%d\n",r2);
    printf("r3=%d\n",r3);
    printf("r4=%d\n",r4);
    
    return 0;
}
----------------------------------------------------------------------------------
五、Question
#include<stdio.h>
int main(){
    int answer1,answer2;
    char words1[5000],words2[5000];
    
    printf("什么动物可以贴在墙上？\n");
    printf("1.大象\n");
    printf("2.老鼠\n");
    printf("3.海豹\n");
    printf("你的选择_____(小孩子才做选择，我全都要)\n");
    scanf("%d",&answer1);
    if(answer1==3)
        printf("请补充说明你的想法:\n");
    else if(answer1==2)
        printf("你确定吗？小老鼠又有什么坏心思呢？\n");
    else if(answer1==1){
        printf("那么把一头大象放进冰箱需要几步？\n");
        printf("4.3步\n");
        printf("5.n步\n");
        scanf("%d",&answer2);
        if(answer2==4)
            printf("clever！\n");
        else if(answer2==5){
            printf("建议选4呢亲\n");
            getchar();
            gets(words1);
               }    
        getchar();
        gets(words2);
    } 
    
    return 0;
    
    
}
