错误信息：
: error C2059: syntax error : ';'
: error C2108: subscript is not of integral type
: error C2296: '*' : illegal, left operand has type 'double [5]'
Error executing cl.exe.

｛｛｝，｛｝，｛｝...｝

知道了 是
改为：int M,i,j;
      double m,Tong;
      ....

第一句int M 后面加上i;
第二句double i,j,m,Tong,;这一句去掉i,去掉Tong后面的逗号。
最后一句 printf("7.2lf",Tong); 应改为 printf("%7.2lf",Tong);加上百分号


改正之后代码如下
#include "stdio.h"
void main()
{
  int M,i;
  double j,m,Tong;
  double Dinge[7][5]={13.37,8.85,4.48,1.85,34.22,
                      18.14,9.75,4.89,1.98,36.00,
                      27.06,13.68,5.50,2.35,41.02,
                      45.02,19.40,5.50,2.84,47.70,
                      71.93,22.93,9.16,3.22,52.94,
                      108.23,26.76,9.16,3.64,58.63,
                      175.22,46.99,27.49,4.98,98.22};
   scanf("%d",&i);
   printf("\n");
   scanf("%d",&M);
   m=M/1000.0;
   Tong=Dinge[i][0]*m;
      printf("%7.2lf",Tong);
}
保证完美运行通过

哈哈，全是初级错误，楼主努力啊

没看懂这个代码啥意思。。。
