     First, eat different foods, especially fruit and vegetables. You may have a favourite food, but you'd better eat

something different.If you eat different foods, you will probably get more nutrients(营养物质) your body needs.

     Second, drink water and milk as often as possible. When you're really thirsty, cold water is the No.l choice(选择).

     Third, listen to your body. How do you feel when you are full? When you are eating, notice how your body feels

and when your stomach(胃) feels comfortably full. Eating too much will not make you feel comfortable and make you

good to take more exercise such as basketball, bike riding and swimming. You can't watch TV for more than two hours

a day.

在文件IN.dat中有200组数据,每组有3个数,每个数均是三位数。函数Rdata()读取这 200组数据存放到结构数组aa中,请编写函数greatSort(),其功能是:要求在200组数据中找出条件为每组中的第1个数大于第2个数加第3个数的和,其中满足条件的组数作为函数 greatSort()的返回值,同时把满足条件的数据存入结构数组bb中,再对bb中的数据按照每组数据的第1个数加第3个数之和的大小进行升序排列(第1个数加第3个数的和均不相等),排序后的结果仍重新存入结构数组bb中。最后调用函数Wdata(),把结果bb输出到OUT.dat文件中。
注意:部分源程序已经给出。请勿改动主函数main()、读数据函数Rdata()和输出数据函数Wdata()的内容。
#include <stdio. h>
#include <string.h>
#include <conio. h>
typedef struct
int x1, x2, x3;
data;
data aa[200], bb[200];
int greatSort ()void Rdata ()
FILE *in;
int i;
in = fopen("IN.dat", "r");
for (i=0; i<200; i++)
fscanf (in, "%d %d %d", &aa[i]. x1, &aa[i] .x2, &aa[i] .x3);
fclose (in);void Wdata(int count)
FILE *out;
int i;
out = fopen("OUT.dat", "w");
for (i=0; i<count; i++)
printf("%d,%d,%d 第一个数+第三个数=%d\n", bb[i].x1,
bb[i].x2, bb[i].x3, bb[i].x1 + bb[i]. x3);
fprintf (out, "%d %d %d\n", bb[i] .x1, bb[i] .x2,
bb[i] .x3);

fclose (out);void main ()
int count;
Rdata ( );
count = greatSort() ;/* 返回满足条件的个数 */
Wdata (count);
