int years = 0;
double rate, investment;

printf("원금 :");
scanf("%f", &investment);
printf("이율 :");
scanf("%f", &rate);

double total = investment;

while (total < investment * 2)
{
    total = total * (1 + rate);
    years += 1;
}
printf("%d년", years);

return 0;

왜 while 문 내에서 years 반복이 적용되서 출력이 안될까요?

for 문 탈출이 안되는데 어떻게 해야할지 알 수 있을까요?
