#include <stdio.h>

int main(){

? ? int age = 18;

float height = 1.85;

char unit = 'm';

printf("小明今年%d歲\n", age);

printf("小明身高%fm\n", height, unit);

printf("%c小明現(xiàn)在在慕課網(wǎng)上學(xué)習(xí)IT技術(shù)");?

return 0;

}

那條不用寫 好像可以直接輸出

#include <stdio.h>
int main(){
??? int age = 18;
?float height = 1.85;
?char unit = 'm';
?printf("小明今年%d歲\n", age);
?printf("小明身高%f%c\n", height, unit);
?printf("小明現(xiàn)在在慕課網(wǎng)上學(xué)習(xí)IT技術(shù)");
?return 0;
}

我是這么寫的，過了，供你參考

#include?<stdio.h>
int?main()
{
??printf("小明現(xiàn)在在慕課網(wǎng)上學(xué)習(xí)?");
??return?0;
}
