Write a program that checks whether or not a date entered in by the user is valid. Display the date and say if it is valid. If it is not valid explain why.

• The input may be in the format mm/dd/yyyy, m/d/yyyy, mm/d/yyyy, or m/dd/yyyy.
• A valid month (mm) must be from 1 to 12
• A valid day (dd) must be from 1 to the appropriate number of days in the month
  • April, June, September, and November have 30 days
  • February has 28 except for leap years, then it has 29
  • The rest have 31 days
  • Leap years are years that are divisible by 4 BUT not divisible by 100 unless it is also divisible by 400

I don't need the coding. Just help with the questions 1 and 2.

1. Include a flow chart in your proposed solution section
2. Write the equivalent Boolean expression !(a>b)&&!(b==c) which doesn’t use the NOT operator (!). Assume that a, b, and c are integers.

Using the idea of the Bubble Sort algorithm, design an algorithm in pseudocode that gets 3 numbers a, b, c, from the user, and prints the 3 numbers in ascending order

In each of the projects that follow, you should write a program that contains an introductory docstring. This documentation should describe what the program will do (analysis) and how it will do it (design the program in the form of a pseudocode algorithm). Include suitable prompts for all inputs, and label all outputs appropri- ately. After you have coded a program, be sure to test it with a reasonable set of legitimate inputs.

5 An object’s momentum is its mass multiplied by its velocity. Write a pro- gram that accepts an object’s mass (in kilograms) and velocity (in meters per second) as inputs and then outputs its momentum.

6 The kinetic energy of a moving object is given by the formula KE=(1/2)mv2, where m is the object’s mass and v is its velocity. Modify the program you created in Project 5 so that it prints the object’s kinetic energy as well as its momentum.

Write a program that takes as input a number of kilometers and prints the corresponding number of nautical miles. Use the following approximations:

- A kilometer represents 1/10,000 of the distance between the North Pole and the equator.

- There are 90 degrees, containing 60 minutes of arc each, between the North Pole and the equator.

- A nautical mile is 1 minute of an arc.

*please use IDLE( python 3.7)

Please convert decimal value -32760 into 2's complement binary value

Part 2: Insertion Sort

Q3. Arrange the following arrays in ascending order using Insertion sort. Show all steps.

7          11        2          9          5          14

Q4. State the number of comparisons for each pass.

convert 0x41BA8000 to IEEE-754 floating-point value

Using Java:

1. Implement print2D(A) so that it prints out its 2D array argument A in the matrix form.

2. Implement add2Ds(A,B) so that it creates and returns a new 2D array C such that C=A+B.

3. Implement multiScalar2D(c,A) so that it creates and returns a new 2D array B such that

   B=c×A.

4. Implement transpose2D(A), which creates and returns a new 2D array B such that B is

   the transpose of A.

Your output should look like the following:A=

1234 5678 9 10 11 12

B=

2468 10 12 14 16 18 20 22 24

A+B=

3 6 9 12 15 18 21 24 27 30 33 36

5XA=

51015 20 25 30 35 40 45 50 55 60

Transpose of A =

159 2 6 10 3 7 11 4 8 12

Note that your methods should work for 2D arrays of any sizes.

Complete the code that inserts elements into a list. The list should always be in an ordered state.

* Elements added to the list must be inserted maintaining the list
* in an ordered state
*/
int main() {
struct element *listhead = NULL;
listhead = listinitialize();
for (int i = 3; i < 100; i+=11){
listhead = insertnewelement(listhead, i);
}
printlist(listhead);
}

/* allocate memory for a new list element */
struct element *elementalloc(void) {
return (struct element *)malloc(sizeof(struct element));
}

/* simple list initialization function */
struct element *listinitialize() {
const int numbers[7] = {4, 9, 13, 18, 27, 49, 60};
struct element *newlist = NULL;
struct element *tail = NULL;
struct element *temp = NULL;
for (int i = 0; i < 7; i++) {
if (newlist == NULL) {
newlist = elementalloc();
newlist->next = NULL;
newlist->value = numbers[i];
tail = newlist;
} else {
temp = elementalloc();
temp->value = numbers[i];
temp->next = NULL;
tail->next = temp;
tail = tail->next;
}
}
return newlist;
}

/* function to insert elements into an ordered list */
struct element *insertnewelement(struct element *listhead, int x) {
struct element *newelement;
newelement = elementalloc();

struct element *iter = listhead;
while( ) {

}

return listhead;
}

/* print the list and the respective memory locations in list order */
void printlist(struct element *listhead)
{
while (listhead != NULL) {
printf("Memory: %p contains value: %d\n", listhead, listhead->value);
listhead = listhead->next;
}
}

How do I change my if statements into while and for loops, so that I can make my bot go straight and turn exactly 12 times.

/***********************************************************************
* Exp7_1_RotaryEncoder -- RedBot Experiment 7_1
*
* Knowing where your robot is can be very important. The RedBot supports
* the use of an encoder to track the number of revolutions each wheels has
* made, so you can tell not only how far each wheel has traveled but how
* fast the wheels are turning.
*
* This sketch was written by SparkFun Electronics, with lots of help from
* the Arduino community. This code is completely free for any use.

1. Create, and write, three people's names into an external file named "names.txt."  You should overwrite the file if it already exists.
2. Read those three people's names into the program from the text file and print them out to the end user's console.
3. Append three more people's names to the external file named "names.txt."
4. Read those six people's names from the text file into the program and print them out to the end user's console.

Then try:

• Get the filename from the end user for all file I/O
• Get the number of names from the end user for all file I/O
• Use loops to get the names from the end user for all file I/O
• Use a loop to repeat the program if the end user desires
