题目大意：给你几个数，求奇数的乘积和
解题思路：
很水，不需要数组的，一个变量 x 就行
代码：
1 #include<iostream> 2 using namespace std; 3 int main() 4 { 5 int sum; 6 int n; 7 int a[100]; 8 while(cin >> n) 9 { 10 sum = 1; 11 for(int i = 0; i < n; i ++) 12 { 13 cin >> a[i]; 14 if(a[i] % 2 != 0) 15 sum *= a[i]; 16 } 17 cout << sum << endl; 18 19 } 20 }
优化：
1 #include<iostream> 2 using namespace std; 3 int main() 4 { 5 int sum; 6 int n; 7 int x; 8 while(cin >> n) 9 { 10 sum = 1; 11 for(int i = 0; i < n; i ++) 12 { 13 cin >> x; 14 if(x % 2 != 0) 15 sum *=x; 16 } 17 cout << sum << endl; 18 19 } 20 }
