C语言程序错误...Turbo C&C++ 3 运行有4处错误

#include <stdio.h>
#include <stdlib.h>
#include <time.h>
void main()
{
int magic,guess,a=1;
char r;
srand(time(0));
magic = rand() % 100 + 1;
do
{
for(;a<10;)
{
printf("Input a number\n");
scanf("%d",&guess);
a++;
if(guess==magic)
{
printf("Right\n");
a==1? printf("You just guessed once\n"): printf("You have guessed %d times\n",a)break;
}
else
{
printf("Wrong\n");
guess>magic? printf("Too high\n"): printf("Too low\n")
}
}
for(;a==10;)
{
printf("Do you want to play again?\n");
a=1;
scanf("%c",&r);
}
}
while(r=='Y');
}

其实也没什么大错。就以下几点：

#include <stdio.h>
#include <stdlib.h>
#include <time.h>
int main()//这里要改int。
{
int magic,guess,a=1;
char r;
srand(time(0));
magic = rand() % 100 + 1;
do
{
for(;a<10;)
{
printf("Input a number\n");
scanf("%d",&guess);
a++;
if(guess==magic)
{
printf("Right\n");
a==1? printf("You just guessed once\n"): printf("You have guessed %d times\n",a);break;//break前面要加；
}
else
{
printf("Wrong\n");
guess>magic? printf("Too high\n"): printf("Too low\n");//这里没加；
}
}
for(;a==10;)
{
printf("Do you want to play again?\n");
a=1;
scanf("%c",&r);
}
}
while(r=='Y');
return 0;
}

#include <stdio.h> #include <stdlib.h> #include <time.h> void main() { int magic,guess,a=1; char r; srand(time(0)); magic = rand() % 100 + 1; do { for(;a<10;) { printf("Input a number\n"); scanf("%d",&guess); a++; if(guess==magic) { printf("Right\n"); a==1; printf("You just guessed once\n"); printf("You have guessed %d times\n",a); break; } else { printf("Wrong\n"); guess>magic? printf("Too high\n"): printf("Too low\n") ; } } for(;a==10;) { printf("Do you want to play again?\n"); a=1; scanf("%c",&r); } } while(r=='Y'); }
