이 제품은 ATM 스타일의 프로그램이지만, 현재는 내가해야 할 일을 정확하게하지 않습니다 현재 잔고, 그리고 돈이 수표 또는 예금에서 이체 될 때, 그것은 수표에 그것을 추가하고 저축에서 그것을 뺀다. 이는 입력 예 다음은올바르게 파일의 요소를 덮어 쓰기에 문제를 갖는 (숫자)는
-=[ Funds Transfer ]=-
-=[ Savings to Checking ]=-
Account Name: nomadic
Amount to transfer: $400
New Balance in Checking: $900 // original was 500
New Balance in Savings: $7.7068e+012 // this should now be 1100...

... 않는, 그러나 제대로 수행하지 않는, 그래서 IDE로를 던지고 컴파일, 그것은 코드의 많은,하지만 오류가 없습니다 누구든지 도움을 받으려면 상당히 빨리해야합니다.
