Yesterday, my friend entrusted me to do a course design based on C++. The topic is as follows:
Design a simple personal income and expense management system, including at least the following functions:
1. Input the details of personal income or expenditure one by one, and write them into the file for saving. Input and add them continuously.
The detailed data input includes: income and expenditure details category code, date of occurrence, amount and remarks.
1) To simplify the user's input, the category code is composed of letters and Numbers: "a" means revenue and "b" means expenditure
The number is the number under the big category. The category code and the corresponding category name are defined and organized in the program
And output display. For example, a1 represents the living expenses of the income category,b1 represents the learning of the expenditure category, and the number increases successively.
The number and name of the categories are drawn up according to daily needs.
Such as:
Income category: a1 with living expenses, a2 with scholarship, a3 with contributions
Expenditure categories: b1, b2, b3, games
2) The user enters the details of income and expenditure. The specific input format is as follows (each data is separated by one or more consecutive Spaces.
Enter enter directly to indicate the end of input) :
Please enter the category code, date of occurrence, amount and remark:
Input income and expense details: a1, 2020, 1, 26, 2000.0 Living expenses for January
Enter income and expenditure details: b1 2020, w3, w9 52.5 Buy books
...
Enter the income and expenditure details: b2 2020 buy desk lamp by 5 ° C and 978.00 ° C
3) Write the input detailed data to a file for saving, so as to facilitate subsequent append and processing.
2. Complete the summary, function design and code implementation according to the daily needs of personal income and expenditure management. Need to be
Statistics and output the summary of each income and expenditure category entered by the user in the month, after output, ask the user again whether input
Each detail of the month, the user answered yes, then according to the details of the type of ascending output; Answer no, do not output.
The input and output results are as follows:
Please enter the month in which the revenue and expenditure category data were aggregated: 20120.3
Summary of income and expenditure category data in March 2020
Income/expenditure detail category amount
Income living expenses 2000
...
Spend 200 on school supplies
...
The total income in March 2020 is 1500, and the total expenditure is 1200
Whether to output each detail of this month (y is output, others are not output) : y
Details of income and expenditure category data in March 2020
Class Income/expenditure date of occurrence amount notes
Living expenses Income 2020 w03 w01 2000.0 March living expenses
School supplies expenditure 2020 w03 w03 10.0 Pens
...
Oneself knocked 1 times, specific implementation is as follows:
