求c语言测试程序

#include <stdio.h>

#define N 5

int even(int a)

{ return 1-a%2

}

int main()

{ int i,x

for(i=0i<Ni++)

{ scanf("%d",&x)

if(even(x))printf("odd:%d ... %d Onum:%d\n",x,x,x)

else printf("even:%d ... %d Enum:%d\n",x,x,x)

}

return 0

}

============

#include <stdio.h>

int isPrime(int n)

{ for(int i=2i*i<=ni++)

if(n%i==0)return 0

return n>1

}

int main()

{ int n,i,k=0

scanf("%d",&n)

printf("%s\n",isPrime(n)?"Yes":"No")

return 0

}

#include #include int main( ) { long start,endstart = clock()//测试的程序段 end = clock()printf("%ld\n",start-end)//单位：毫秒 return 0}
