while(scanf("%d",&n)!=EOF)

{

getchar();

ret = 1;

for(; n>0; n--)

{

scanf("%d",&num);

if(num%2!=0)

ret *= num;

}

printf("%d\n",ret);

}

return 0;

2007 平方和与立方和

#include

int my_math1(int x,int y)

{

int i;

int sum = 0;

for(i=x; i<=y; i++)

{

if(i%2==0) //偶数平方和

sum += i*i;

}

return sum;

}

int my_math2(int x,int y)

{

int i;

int sum = 0;

for(i=x; i<=y; i++)

{

if(i%2) //奇数立方和

sum += i*i*i;

}

return sum;

}

int main()

{

int m,n,x,y,temp;

while(scanf("%d%d",&m,&n)!=EOF)

{

getchar();

if(m>n)//保证m小于n

{

y = my_math2(m,n);

printf("%d %d\n",x,y);

}

return 0;
