快来人嘛  在线等撒

行数相加 然后表示出来  怎么做不出来呢....

#include <stdio.h>

int main()
{
    int i,j;
int a[5][5] = {{0, 1, 2, 3, 4}, {1, 2, 3, 4, 5}, {2, 3, 4, 5, 6}, {3, 4, 5, 6, 7}, {4, 5, 6, 7, 8}};
for (i = 0; i < 5; ++i)
{
  int sum = 0;
  for (j = 0; j < 5; ++j)
  {
   sum = sum + a[i][j];
  }
  printf("Line %d sum = %d\n", i, sum);
}
return 0;
}

呵呵 这么简单 见笑了哈
