include <stdio.h>
int main(){
int age = 18;
float height = 1.85;
char unit = 'm';
printf("小明今年%d岁\n", age);
printf("小明身高%f,%c\n", height, unit);
printf("小明现在在慕课网上学习IT技术");
return 0;
}
要通过验证的话 是IT技术后面加%c 身高后面的%c去掉
#include <stdio.h>
int main()
{
int age = 18;
float height = 1.85;
char unit = 'm';
printf("小明今年%d岁\n", age);
printf("小明身高%f,%c\n", height, unit);
printf("小明现在在慕课网上学习IT技术");
return 0;
}开头include前面有个#号，还有书写不规范的问题，注意缩进和全角半角的标点符号，好像就这样了吧
