这一句提示语的意思是说：在printf前面大概丢掉了分号（；）。c语言中的出错提示语都说的是大概。找错误时在printf前后检查有没有语法错误，而不仅仅检查是不是丢掉分号。在你发来的程序段中，printf语句前后没有发现语法错误。我判断错误是不是出现在chenge() 函数中，你没有把chenge函数的内容发来，...

你这里报错的原因是 :do { }while(i<=1000); 这里while应该写在后边且必须加分号，你当中写的do while 循环是错误的写法，故而会报一个语法错误，另外就是你的程序逻辑 控制 还有几处错误 具体修改程序后为：include<stdio.h> int main(){ int i=100,a,b,c;printf("水仙花数为:");do...
