一直提示function call missing >in function prime就是没找到问题在哪!!
#include<math.h>
int prime(int n)
{int i,p=1;
 fot(i=2;i<n/2&&p==1;i++)
 if(n%i==0)
 p=0;
 return(p);
}
main()
{
 int m;
 printf("Input an integer:");
 scanf("%d",&m);
 if(prime(m))
 printf("%d is a prime\n",m);
 else
 printf("%d is not a prime\n",m);
}

thank you!!终于找出来了
