在一个程序里咋实现,按功能分步我好像会,但是一整个好像有点难

设计世界杯比赛计分与显示程序。共32队参赛(参赛队名自定)。小组分为8组,每组4队(随机分组),采用循环比赛,各队前两名进入16(积分规则同国际足联世界杯规则),以后各轮采用随机分组,单败淘汰赛,直到决出最后冠军。要求该程序:

(1) 进行小组赛分组,显示分组结果;

(2) 能输入小组赛每一轮比赛结果,显示小组赛各组积分、净胜球等成绩及小组排名,显示进入前16名单。编排前16对阵名单并输出;

(3) 同样编排并显示16 8 4 2赛对阵名单(在上一轮比赛结束以后),输入各轮对阵比赛结果,显示各阶段比赛优胜队,直至冠军。
软件用的vc6.0

你每个功能分布都能搞出来,整合一下不就可以吗

整合就更简单了,你把每个部分写成一个程序,然后分别把main改为main1 main2 main3
再写一个程序,加上

#include <stdio.h>
extern int main1();
extern int main2();
extern int main3();
int main()
{
while (1) {
printf("请选择功能:1 xxx 2 xxx 3 xxx ... 0退出");
int n;
scanf("%d", &n);
if (n == 1) main1();
if (n == 2) main2();
if (n == 3) main3();
if (n == 0) break;
}
}
