# Write a program that asks the

Write a program that asks the user to enter a person’s age. The program should display a message indicating whether the person is an infant, a child, a teenager, or an adult.
Following are the guidelines:
•  If the person is 1 year old or less, he or she is an infant.
•  If the person is older than 1 year, but younger than 13 years, he or she is a child.
•  If the person is at least 13 years old, but less than 20 years old, he or she is a teenager.
•  If the person is at least 20 years old, he or she is an adult.

# Write a program that asks the

Python

Write a program that asks the user for two integers that will correspond to the numbering of the first and last lines, then a third integer that will correspond to the number of z before “zigzag” (not counting the first “z” of zigzag), then finally that displays a zig-zag following the following pattern:

Exemple 1:

Start Number: * user type 3 *

End number:   * user type 10 *

Number of z:   * user type 5 *

zzzzzzigzag 3

4 zzzzzzigzag

zzzzzzigzag 5

6 zzzzzzigzag

zzzzzzigzag 7

8 zzzzzzigzag

zzzzzzigzag 9

10 zzzzzzigzag

(Even integers must be left-zigzag and odd integers must be right.)

Example 2:

Start number:* user type -2 *

End Number:* user type 4 *

Number of z: * user type 3 *

-2 zzzzigzag

zzzzigzag -1

0 zzzzigzag

zzzzigzag 1

2 zzzzigzag

zzzzigzag 3

4 zzzzigzag

Example 3:

Start Number:* user type 5 *

End number:* user type 0 *

Number of z: * user type 10 *

(Nothing is displayed because 5>0)

# Write a program that asks the

Please provide Java source code for following project with proper comments.

Write a program that asks the user to enter a distance in meters. The program will then pre-sent the following menu of selections:

1. Convert to kilometers

2. Convert to inches

3. Convert to feet

4. Quit the program

The program will convert the distance to kilometers, inches, or feet, depending on the user’s selection. Here are the specific requirements:

• Write a void method named showKilometers, which accepts the number of meters as an argument. The method should display the argument converted to kilometers. Convert the meters to kilometers using the following formula:

kilometers = meters * 0.001

• Write a void method named showInches, which accepts the number of meters as an argument. The method should display the argument converted to inches. Convert the meters to inches using the following formula:

inches = meters * 39.37

• Write a void method named showFeet, which accepts the number of meters as an argument. The method should display the argument converted to feet. Convert the meters to feet using the following formula:

feet = meters * 3.281

• Write a void method named menu that displays the menu of selections. This method should not accept any arguments.

• The program should continue to display the menu until the user enters 4 to quit the program.

• The program should not accept negative numbers for the distance in meters.

• If the user selects an invalid choice from the menu, the program should display an error message.

Here is an example session with the program, using console input. The user’s input is shown in bold.

Enter a distance in meters: 500 [Enter]

1. Convert to kilometers

2. Convert to inches

3. Convert to feet

4. Quit the program Enter your choice: 1 [Enter]

500 meters is 0.5 kilometers.

1. Convert to kilometers

2. Convert to inches

3. Convert to feet

4. Quit the program

Enter your choice: 3 [Enter]

500 meters is 1640.5 feet.

1. Convert to kilometers

2. Convert to inches

3. Convert to feet

4. Quit the program

Enter your choice: 4 [Enter]

Bye!

# Write a program that asks the

Do not write the code in multiple programs. Both methods (a and b) should be written in 1 program.

1. Write a program that asks the user to input two integers a and b. Pass the two input integers to method called “createArray”. Then create an array that has all integer from a to b. Return the array to main method and print the array from the main method

Example 1:

Input two numbers: 6 2

Array is [6, 5, 4, 3, 2]

Example 2:

Input two numbers: 4 8

Array is [4, 5, 6, 7, 8]

1. Pass the above array as a parameter to a method called average and return the average and print it out in the main method.

# Write a program that asks the

Instructions from your teacher:
Write a program that asks the user to enter a character. Then pass the character to the following methods.

changeCase() – if the character is lower case then change it to upper case and if the character is in upper case then change it to lower case.

Example output is given below:
Enter a character
a
a is equivalent to A

Note: Java represents character using Unicode encoding and ‘A’ to ‘Z’ is represented by numbers 65 to 90 and ‘a’ to ‘z’ is represented by numbers 97 to 122. So to convert ‘A’ to ‘a’ you need to add (97-65) to A and then cast it to Character type since the addition will change its type to integer.
You can use the following code to read a character from console. When you call charAt(i) method for any String it returns the character at index i. The index of first character is 0, the index of second character is 1 and so on.
Scanner input = new Scanner(System.in); char ch =input.next().charAt(0);

If you cannot pass the tests, please try following for troubleshooting:
changeCase(‘c’); # should be ‘C’
changeCase(‘C’); # should be ‘c’

class Main {

public static void main(String[] args) {

char a = (char) 65;

System.out.print(a);

}

public static char changeCase(char c) {
// ASCII
// a <==> 97 b = 98,
// A 65 B 66

// ‘a’ – (97-65) = ‘A’
// ‘A’ + (97-65) = ‘a’
return ‘a’;
}
}

# Write a program that asks the

Write a program that asks the user for the name of a file, and an integer number. The program should display the first several lines of the file on the screen, and the number of lines should be equal to the integer entered by the user. If the number of lines the file has is less than the integer entered by the user, then the entire file should be displayed, with a message indicating the entire file has been displayed.

When evaluating the peer submissions, please consider two cases to verify the program, with one case where the file has enough lines, and one case where the file does not have enough lines.

Please submit your solution to the lab instructor once you have your program working. Your lab instructor will tell you how (s)he would like you to turn it in.

Failure to submit will result in a zero.

1. Write a program that asks the user to input two integers a and b. Then create an array that has all integer from a to b. Print out the array.

(Don’t forget to consider the situation of a=b, a<b, and a>b.)

Example 1:

Input two numbers: 6 2

Array is [6, 5, 4, 3, 2]

Example 2:

Input two numbers: 4 8

Array is [4, 5, 6, 7, 8]

1. Pass the above array as a parameter to a method called average and return the average and print it out in the main method.

(Do not use Math library to get the average.)

# Write a program that asks the

Program 1:

1. Write a program that asks the user to input a sentence and then outputs the sentence back with the case of every character reversed.

2. So for example: “CaTs RuLe!” would be given back as “cAtS rUlE!” .

3. Spaces and punctuation should be left in place.

4. You can use the Character class static functions to test the case of each letter.

5. You do not need to place any code in static methods (besides the main method), you do not need to worry about try/catch blocks, and you do not need to make the program run more than once.
