- Write in c++ ....arrow_forwardPls make a code for this on c++ and make sure it is 100% correct. i wastred 4 questoins on this and they all are not correct. Write the code as described in the questions below. Submit your code electronically in the box at the bottom. You may only use Java, C# or C++. The economy is defined using a 2-dimensional data structure: A “payday” will be considered to be any region of $ values where all cells in the region are connected either vertically or horizontally. For example, the following illustrates a matrix with 5 rows and 8 columns containing three objects. $’s and P are used in the diagram to represent the two types of values: PPPP$PPPPPP$$PPPPP$$PPP$PP$PPPP$P$PPP$$$ a) Write a program to read in the data from the text file and store it into a data structure. Your program should output it to the screen after it has read in the file. (If you can’t get this to work hard-code the above example and continue to part b).

Please don't copy similar programs from, bartleby or chegg Define a structure type auto_t to represent an automobile. Include components for the make and model (strings), the odometer reading, the manufacture and purchase dates (use another user-defined type called date_t), and the gas tank (use a user-defined type tank_t with components for tank capacity and current fuel level, giving both in gallons). Write I/O functions scan_date, scan_tank, scan_auto, print_date, print_tank, and print_auto, and also write a driver function that repeatedly fills and displays an auto structure variable until input is -30. Note: Each record has a number (1, 2, 3 ...),once the program scans record number -30, it should terminate without processing it.
