include〈stdio.h〉是C语言程序的头文件以“.h”为后缀。在这里的编译预处理命令称为文件包含命令，其作用是在编译之前把程序需要使用的关于系统定义的函数printf（）的一些信息文件stdio.h包含进来。以“.h”作为后缀的文件称为头文件。在使用标准函数库中的输入输出函数时，编译系统要求程序提供有关的...

1、int x,int y;改成int x;int y;2、y=100c+10b+a;改成y=100*c+10*b+a;3、加上头文件#include<stdio.h> 4、修正后的代码：include<stdio.h> int main(){int x;int y;int a,b,c;printf("Please input a num:");scanf("%d",&x);a=x/100;b=x/10%10;c=x%10;y=100...
