Question

コード割り当てがあります。

A bank charges $10 per month plus the following check fees for a commercial checking account: 

$0.10 each for fewer than 20 checks 
$0.08 each for 20-39 checks 
$0.06 each for 40-59 checks 
$0.04 each for 60 or more checks 
The bank also charges an extra $15.00 if the balance of the account falls below $400 (before any check fees are applied). Write a program named lab2 that inputs for the beginning balance and the number of check written from the transaction file. Compute and display the bank's service fees for the month. 

Input Validation: Do not accept a negative value for the number of checks written. If a negative value is given for the beginning balance, display an urgent message indicating the account is overdrawn. 
The program should have a loop execution of six times for reading data from a file named transaction.txt. 
Click the link transaction.txt download the file and store it in folder c:\cis180\lab2. The file transaction.txt contains the beginning balance and number of checks written for six transactions. 
Here is the content of the file.

//Create a loop to execute 6 times. Each time the loop body reads the beginning balance and number of checks for six transaction, calculate the bank fees, display the beginning balance, number of checks, and the bank fees. 
inputFile >> acctBalance;

// Determine whether the account is overdrawn. 

// Validate number of checks written. 

// If the number of checks is less than 0 

{ // numChecks is valid, so we can calulate the fees. 
// Calculate checkFee - Use if/else if structure 
const double MONTHLY_FEE= 10.00; // Base monthly fee 
const double MIN_BAL= 400.00; // minimum balance 
const double LOW_BAL_FEE= 15.00; // extra fee for low balance

    } 


// Display results: The bank fee 

cout<<"The bank fee this month is "<<totalFees<<endl; 

}//end the loop 


return 0; 
}//end 

そして、私がコンパイルしようとすると、私はエラーを取得しています。

Error E2379 lab3.cpp 33: Statement missing ; in function main() 
Error E2379 lab3.cpp 36: Statement missing ; in function main() 
Warning W8004 lab3.cpp 115: 'transaction' is assigned a value that is never used in function main() 

したがって、基本的に私の唯一の問題は既にタイトルにあります。助けてもらえますか？また、私はC++言語に新しいので、優しくしてください。他に問題がある場合は、私にそれを指摘できますか？前もって感謝します。

Answer 1

あなたはここになぜあなたはSTDLIB.H含めている

cout << "Your beginning balance is: " << acctBalance << endl; 
             ^^ 

、ここ

cout << "The number of checks written were: " << numChecks << endl; 
               ^^ 

を演算子を忘れてしまいましたか？私はあなたがどこでそれを使用しているのかわかりません。このヘッダーが必要な場合は、代わりにcstdlibをお勧めします。

コメントですでに指摘したように、コード内に数行前に表示される{の代わりにセミコロンも使用しました。

if(numChecks < 20) { 

} 

一貫性のあるインデントスタイルを使用すると、読みやすさも向上します。
