3.16 (Gas Mileage) Drivers are concerned with the mileage obtained by their automobiles. One driver has kept track of several tankfuls of gasoline by recording miles driven and gallons used for each tankful. Develop a program that will input the miles driven and gallons used for each tankful. The program should calculate and display the miles per gallon obtained for each tankful. After processing all input information, the program should calculate and print the combined miles per gallon obtained for all tankfuls.
Here is a sample input/output dialog: 3.17 (Credit-Limit Calculator) Develop a C program that will determine whether a department store customer has exceeded the credit limit on a charge account. For each customer, the following facts are available: a. Account number b. Balance at the beginning of the month c. Total of all items charged by this customer this month d.
Total of all credits applied to this customer's account this month e. Allowed credit limit The program should input each fact, calculate the new balance ( = beginning balance + charges – credits ) , and determine whether the new balance exceeds the customer's credit limit. For those customers whose credit limit is exceeded, the program should display the customer's account number, credit limit, new balance and the message “Credit limit exceeded.†Here is a sample input/output dialog: Enter account number (-1 to end): 100 Enter beginning balance: 5394.78 Enter total charges: 1000.00 Enter total credits: 500.00 Enter credit limit: 5500.00 Account: 100 Credit limit: 5500.00 Balance: 5894.78 Credit Limit Exceeded. Enter account number (-1 to end): 200 Enter beginning balance: 1000.00 Enter total charges: 123.45 Enter total credits: 321.00 Enter credit limit: 1500.00 Enter account number (-1 to end): 300 Enter beginning balance: 500.00 Enter total charges: 274.73 Enter total credits: 100.00 Enter credit limit: 800.00 Enter account number (-1 to end): -1

Part 1: Understanding Algorithms, Pseudocode, and Flowcharts
1.1 Algorithms
An algorithm is a step-by-step procedure or formula for solving a problem. It is a well-defined sequence of actions that transforms inputs into desired outputs, typically expressed in finite steps. Algorithms are essential in computer programming because they provide the framework needed to solve complex computational problems.
An effective algorithm must be:
- Clear and Unambiguous: Each step should be precisely defined to avoid confusion.
- Well-Ordered: Procedures must be arranged in a logical order that guarantees reaching the desired outcome.
- Effective: The algorithm should be achievable in a finite amount of time with the available resources.
- General: It should solve not just a specific instance of a problem but a whole class of problems (Cormen et al., 2009).
1.2 Pseudocode
Pseudocode is a high-level description of an algorithm that uses the structural conventions of programming languages but is intended for human reading rather than machine reading. It allows programmers to express ideas in a way that is easy to understand and communicate, before the actual coding in a programming language begins (Rosen, 2012).
Pseudocode is often used to outline algorithms because it strikes a balance between natural language and formal programming syntax. It focuses on the logic and sequence without worrying about specific syntax errors, making it a powerful tool for planning and discussing algorithms.
Example of Pseudocode:
```
BEGIN
SET total = 0
FOR each tankful
INPUT miles driven
INPUT gallons used
mileage = miles driven / gallons used
PRINT mileage
total = total + mileage
END FOR
averageMileage = total / number of tankfuls
PRINT averageMileage
END
```
1.3 Flowcharts
Flowcharts are visual representations of algorithms. They use standard symbols like ovals, arrows, rectangles, and diamonds to illustrate the flow of control and data in a program. Flowcharts make it easier to understand how a process works and to communicate it effectively to others (Levy, 2010).
Key Flowchart Symbols:
- Oval: Represents the start or end of a process.
- Rectangle: Indicates a process, such as actions or computations.
- Diamond: Implements a decision or branching point in the algorithm.
- Arrow: Shows the control flow direction.
A flowchart for the gas mileage program might include:
- Start (Oval)
- Input miles driven and gallons used (Rectangle)
- Calculate mileage (Rectangle)
- Display mileage (Rectangle)
- Repeat for each tankful (Diamond)
- Calculate average mileage (Rectangle)
- End (Oval)
Part 2: C Programming Exercises
2.1 Exercise 3.16 (Gas Mileage)
Here is a C program that calculates the miles per gallon obtained for several tankfuls of gasoline:
```c
#include
int main() {
int tankfuls = 0;
float miles, gallons, totalMileage = 0.0, mileage;
while (1) {
printf("Enter miles driven (or -1 to end): ");
scanf("%f", &miles);
if (miles == -1) {
break;
}
printf("Enter gallons used: ");
scanf("%f", &gallons);
if (gallons == 0) {
printf("Gallons used cannot be zero.\n");
continue;
}
mileage = miles / gallons;
printf("Mileage for this tankful: %.2f miles per gallon\n", mileage);
totalMileage += mileage;
tankfuls++;
}
if (tankfuls > 0) {
printf("Average mileage for all tankfuls: %.2f miles per gallon\n", totalMileage / tankfuls);
} else {
printf("No tankfuls entered.\n");
}
return 0;
}
```
2.2 Exercise 3.17 (Credit-Limit Calculator)
Here is the C program that checks if a customer exceeds their credit limit:
```c
#include
int main() {
int accountNumber;
float beginningBalance, totalCharges, totalCredits, creditLimit, newBalance;
while (1) {
printf("Enter account number (-1 to end): ");
scanf("%d", &accountNumber);
if (accountNumber == -1) {
break;
}
printf("Enter beginning balance: ");
scanf("%f", &beginningBalance);
printf("Enter total charges: ");
scanf("%f", &totalCharges);
printf("Enter total credits: ");
scanf("%f", &totalCredits);
printf("Enter credit limit: ");
scanf("%f", &creditLimit);
newBalance = beginningBalance + totalCharges - totalCredits;
printf("Account: %d\n", accountNumber);
printf("Credit Limit: %.2f\n", creditLimit);
printf("New Balance: %.2f\n", newBalance);
if (newBalance > creditLimit) {
printf("Credit limit exceeded.\n");
} else {
printf("Credit limit not exceeded.\n");
}
}
return 0;
}
```
