求助Fibonacci sequence ,用C解决.
欧拉计划第二题:Each new term in the Fibonacci sequence is generated by adding the previous two terms. By starting with 1 and 2, the first 10 terms will be:
1, 2, 3, 5, 8, 13, 21, 34, 55, 89, ...
By considering the terms in the Fibonacci sequence whose values do not exceed four million, find the sum of the even-valued terms.
[解决办法]
- C/C++ code
#include <stdio.h>#include <stdlib.h>int main(){ int m = 1, n = 2, sum = 2, tmp; while(n < 4000000) { tmp = n; n = m + n; m = tmp; if(n % 2 == 0) sum += n; } printf("%d\n", sum); system("pause"); return 0;}
