实验1

1.垂直小人源码


#include <stdio.h>
#include <stdlib.h>
int main(){
  int i;
  for(i=0;i<=1;i++){
    printf(" O\n");
    printf("<H>\n");
    printf("I I\n");

}
  system("pause");
  return 0;
}

 2 #include <stdlib.h>
 3 int main (){
 4     printf(" O       O\n");
 5     printf("<H>   <H>\n");
 6     printf("I I   I I\n");
 7 
 8     system("pause");
 9     return 0;
10 }

 3 #include<math.h>
 4 int main()
 5 {
 6     float a, b, c;
 7 
 8     scanf_s("%f%f%f", &a, &b, &c);
 9 
10     if (a+b>c || a+c>b || b+c>a) {
11         printf("能构成三角形\n");
12     }
13     else
14     {
15         printf("不能构成三角形\n");
16     }
17 }

 

 

 

三.实验三

  1.源码部分展示

 1 #include <stdio.h>
 2 #include <stdlib.h>
 3 int main(){
 4     char ans1,ans2;
 5     printf("每次课前认真预习、课后复习了没(输入y或者Y表示有,输入n或N表示没有):");
 6 
 7     ans1 = getchar();
 8     getchar();
 9     printf("\n动手敲代码实践了没?(输入y或Y表示敲了,输入n或者N表示没敲):");
10     ans2 = getchar();
11     if((ans1 == 121 || ans1 == 89 ) && (ans2 == 121 || ans2 == 89)){
12         printf("\n罗马不是一天建成的,继续保持哦\n");
13     }
14     else
15         printf("\n罗马不是一天毁灭的,我们来建设吧\n");
16     system("pause");
17     
18 }
