What I have tried:

It keeps saying that i is only declared once. I'm not sure how to fix this.

推荐答案

％。2f ** * \ n，余额）;

如果（余额> = 50000 。 00 ）
{
printf（ < span class =code-string> ***是时候投入一些钱了！*** \ n）;
}
else if （余额> = 15000 。 00 && balance< = 49999 。 9 ）
{
printf（ ***也许你应该考虑一张CD。*** \ n ）;
}
else if （余额> = 1000 。 00 &&余额< = 14999 。 99 ）
{
printf（ ***保持良好的工作！*** \ n）;
}
其他 如果（余额> = 0 。 0 && balance< = 999 。< span class =code-digit> 99 ）
{
printf（ ***你的余额越来越低！*** \ n）;
}
}

void printBankRecord（ float balance_0， float balance， int numDeposits， int numWithdrawals， float depositRecords [ 5 ]， float withdrawRecords [ 5 ]）
{

printf（ \ n）;

printf（ ***银行记录*** \ n\ n ）;

int i = 0 ;
for （i = 0 ; i< numDeposits; i ++）

printf（ 存款＃％d：％。2f \ n，i + 1 ，depositRecords [i]）;
}

for （i = 0 ; i< numWithdrawals; i ++）
