任务1
源代码
#include <stdio.h>
int main()
{
printf(" O O \n");
printf("<H> <H>\n");
printf("I I I I\n");
return 0;
}
#include <stdio.h> int main() { printf(" O \n"); printf("<H>\n"); printf("I I\n"); printf(" O \n"); printf("<H>\n"); printf("I I\n"); return 0; }
运行结果

#include <stdio.h> int main() { char ans1, ans2; printf("每次课前认真预习、课后及时复习了没? (输入y或Y表示有,输入n或N表示没有) :"); ans1 = getchar(); getchar(); printf("\n动手敲代码实践了没? (输入y或Y表示敲了,输入n或N表示木有敲) :"); ans2 = getchar(); if ((ans1 == 'y' || ans1 == 'Y') && (ans2 == 'y' || ans2 == 'Y')) printf("\n罗马不是一天建成的, 继续保持哦:)\n"); else printf("\n罗马不是一天毁灭的, 我们来建设吧\n"); return 0; }
如果删去那一段,则无法进行第二个问题,这一行是为了给ans2赋值
