题意：求斐波那契数列不大于4百万的值为偶数的和
代码如下：
1 #ifndef PRO2_H_INCLUDED 2 #define PRO2_H_INCLUDED 3 #include<iostream> 4 using namespace std; 5 6 namespace pro2{ 7 int solve(){ 8 int p1=1,p2=2,p,sum=0; 9 for(;p1<=4000000;){ 10 if(p1%2==0)sum+=p1; 11 p=p1+p2; 12 p1=p2; 13 p2=p; 14 } 15 return sum; 16 } 17 } 18 19 #endif // PRO2_H_INCLUDED
