Eco cars are still too expensive for most car buyers
Explanation:
Answer:
#include <iostream>
using namespace std;
int main()
{
int length = 8;
int width = 8;
int perimeter = 2*(length + width);
int area = length * width;
cout<<"The perimeter is "<<perimeter<<endl;
cout<<"The area is "<<area<<endl;
return 0;
}
Explanation:
include the library iostream for using the input/output instructions in the c++ programming.
Create the main function and define the variable length and width with values.
Then, use the formula for calculating the perimeter and area of rectangle.


and store in the variables and finally print the output.
Firstly we explain the variable and the declaration rule for the variable and further separating the valid and invalid variables.
- Whenever a user is given a question, variables are data values that can vary. for example age, CSL, etc.
- It may alter and during the execution of the program.
- It's a storage space for memories.
- It has a name that corresponds to the location.
- Data is stored in the memory location.
The rule for variable declaration:
- The names of your variables should be based on the phrases used in the subject area, and they should reflect the variable's function.
- By removing spaces between the words, you can make variable names. Each word in the name should be capitalized, including prepositions and pronouns that are one letter long.
- An underscore should never be used to start a variable name.
- Single-character variable names should be avoided. For loop counters, only short variable names are permitted.
- After the state that equals the "true" value, name variables that describe binary states ("true" or "false").
The valid variable is:
CSL, Age,CLS,SEE,Stop5for,Give, $shopping, and United.
The invalid variable is:
Mark-sheet, Tel $, Simple Interest, and 545Newton.

Answer:
True
Explanation:
A single file can be used to record/ store all the information regarding a transaction because in a transaction there are less complexities. a simple transaction involves an exchange/communication between a buyer and a seller which involves exchange in finances between the buyer and the seller.
An employee can be involved in several activities like work activities and multiple transactions while a single inventory part record is different from an employee's record and any other form of transaction. hence separate files have to be created for each of these activities.
To have an easy access to this information when needed a master file is created to store all the individual files.
