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.
#include
ResponderEliminarlong i,s;
bool d[1001];
int main(){
for(i=1;i<1000;i++)
if((i/3)*3==i)

for(i=1;i<1000;i++)
if((i/5)*5==i)
d[i]=true;
for(i=1;i<1000;i++)
if(d[i]==true)
s=s+i;
printf("%ld",s);
