Question

帮我查看一下这个c语言程序哪里错了，谢谢

#include"time.h"
#include"stdlib.h"
#include"stdio.h"
main()
{int tol=0;
printf("\n*****catch thirty*****\n");
printf("game begin\n");
randomize();
if(random(2)==1)
tol=input(tol);
while(tol!=30)
if( (tol=copu(tol)==30)
printf("you lose! \n");
else
if( (tol=input(tol)==30)
printf("I lose! \n");
printf("*****Game Over*****\n");
}
input(t)
int t;
{int a;
do{
printf("please count:");
scanf("%d",&a);
if(a>2||a<1||t+a>30)
printf(" Error input,again! ");
else
printf("You count:%d\n",t+a);
}while(a>2||a<1||t+a>30);
return(t+a);
}
copu(s)
int s;
{int c;
printf("computer count:");
if((s+1)%3==0)
printf("%d\n",++s);
else if((s+2)%3==0){
s+=2;
printf("%d\n",s);
}
else{
c=random(2)+1;
s+=c;
printf("%d\n",s);
}
return(s);
}
这是错误提示

Answer 1

这东西谁写的= =靠害的么

不知道你用的是什么时候的C了
RANDOM函数大概是在TC的年代才有的东西吧？

另外C有像
copu(s)
int s;
这样子定义函数的么？？

偶孤陋寡闻了……

PS：C里面函数要在使用前先声明的……

Answer 2

C语言里的随机函数是
srand() //初始化
rand() //产生一个随机整数

具体用法上网查查吧

Answer 3

把函数定义放在main函数前面，或者在main之前加个函数声明，还有IF语句后面多了左括号，你再试试

#include"time.h"
#include"stdlib.h"
#include"stdio.h"
input(int t);
copu(int s);
void main()
{int tol=0;
printf("\n*****catch thirty*****\n");
printf("game begin\n");
srand((unsigned)time(NULL));
if(rand()==1)
tol=input(tol);
while(tol!=30)
if(tol=copu(tol)==30)
printf("you lose! \n");
else
if(tol=input(tol)==30)
printf("I lose! \n");
printf("*****Game Over*****\n");
}

input(int t)
{int a;
do{
printf("please count:");
scanf("%d",&a);
if(a>2||a<1||t+a>30)
printf(" Error input,again! ");
else
printf("You count:%d\n",t+a);
}while(a>2||a<1||t+a>30);
return(t+a);
}
copu(int s)
{int c;
printf("computer count:");
if((s+1)%3==0)
printf("%d\n",++s);
else if((s+2)%3==0){
s+=2;
printf("%d\n",s);
}
else{
c=rand()+1;
s+=c;
printf("%d\n",s);
}
return(s);
}

Answer 4

可运行!~
#include"stdlib.h"
#include"stdio.h"
#include"time.h"

void main()
{int tol=0;
printf("\n*****catch thirty*****\n");
printf("game begin\n");
randomize();
if(random(2)==1)
tol=input(tol);
while(tol!=30)
if( (tol=copu(tol)==30) ) //这里少了一个“）”
printf("you lose! \n");
else
if( (tol=input(tol)==30) ) //同上
printf("I lose! \n");
printf("*****Game Over*****\n");
}
input(t)
int t;
{int a;
do{
printf("please count:");
scanf("%d",&a);
if(a>2||a<1||t+a>30)
printf(" Error input,again! ");
else
printf("You count:%d\n",t+a);
}while(a>2||a<1||t+a>30);
return(t+a);
}
copu(s)
int s;
{int c;
printf("computer count:");
if((s+1)%3==0)
printf("%d\n",++s);
else if((s+2)%3==0){
s+=2;
printf("%d\n",s);
}
else{
c=random(2)+1;
s+=c;
printf("%d\n",s);
}
return(s);
}

Answer 5

input(t)
int t;
{int a;
这个{在{int t；
你的错误提示是{迷或者错误了
randomize();没有声明定义
