# Accept string input.

# Count and display total i charter in the string.

# Accept student name and grade and save it to a dictionary.

# Display the content of the dictionary.

# Display the name and grade of student with the highest and lowest grade.

# Accept integer number and store it to a list until user input is 0.

# Display the content of the list and size of the list.

# Display the highest and lowest numbers in the list and the index number it can be found.

Create a new project, and include in it the class

Create a class "Student" and another class "Teacher", both descendants of

"Person".

The class "Student" will have a public method "GoToClasses", which will

write on screen "I’m going to class."

The class "Teacher" will have a public method "Explain", which will show on

screen "Explanation begins". Also, it will have a private attribute "subject", a

string.

The class Person must have a method "SetAge (int n)" which will indicate

the value of their age (eg, 20 years old).

The student will have a public method "ShowAge" which will write on the

screen "My age is: 20 years old" (or the corresponding number).

You must create another test class called "StudentAndTeacherTest" that will

contain "Main" and:

Create a Person and make it say hello

Create a student, set his age to 21, tell him to Greet and display his age

Create a teacher, 30 years old, ask him to say hello and then explain.

Test the other methods also given in the diagram

Write a program to print all the composite numbers between a and b

Instructions

1. Define the hasVowel() function with the following details
2. Return type - int
3. Name - hasVowel
4. Parameter:
5. char* - to hold the character array
6. Return value - 1 if there is at least 1 vowel and 0 if there is none. Be sure to consider both the capital and small letter vowels when checking.

Given code

#include <iostream>

using namespace std;

int main(void) {

  char word[100];

  cout << "Enter the word: ";

  cin >> word;

  int result = hasVowel(word);

  if(result == 1) {

    cout << "There is a vowel in the word \"" << word << "\"";

  } else if(result == 0) {

    cout << "There is no vowel in the word \"" << word << "\"";

  }

  return 0;

}

Ex

Enter·the·word:·CodeChum

There·is·a·vowel·in·the·word·"CodeChum"

Instructions:

1. Declare and define display() function with the ff. details:
2. Return type - void
3. Name - display
4. Parameters
5. int* - an array
6. int - the size of an array

Given code

#include <iostream>

using namespace std;

// TODO: Declare the display() function here

int main(void) {

  int world[100] = {

    1,3,2,4,5,7,6,8,9,11,

    100,13,0,14,16,17,3,18,20,10,

    12,8,15,14,-5,17,19,18,1,9,5,

    10,13,11,14,16,22,0,18,20,3,

    99,13,15,14,22,17,19,0,23,2,

    12,13,15,22,16,17,56,18,44,99,

    2,13,22,14,16,89,19,69,101,34,

    12,22,15,14,78,17,69,18,2,33,

    4,13,77,7,10,17,19,91,4,22,

    12,98,15,14,15,17,19,18,7

  };

  display(world, 100);

  return 0;

}

// TODO: Define the display() function here

Element·at·index·0:·1

Element·at·index·1:·3

Element·at·index·2:·2

Inst.

1. Implement the findRing() function w/ the ff. details
2. Return type int
3. Name findRing
4. Parameters
5. int* - rings array
6. int - array size of rings
7. int - ring she wants
8. Return value - the index of the ring in the array of rings.

Given code

#include <iostream>

using namespace std;

// TODO: Declare findRing()

int main(void) {

  int rings[10];

  for(int i = 0; i < 10; i++) {

    cout << "Enter option #" << i + 1 << ": ";

    cin >> rings[i];

  }

  int wantedRing;

  cout << "Enter the ring she wants: ";

  cin >> wantedRing;

  cout << endl << "Ring " << wantedRing << " is found at option " << findRing(rings, 10, wantedRing) + 1 << "!";

  return 0;

}

// TODO: Define findRing()

Ex

Enter option #1: 5

Enter option #2: 3

Enter option #3: 10

Enter option #4: 9

Enter option #5: 13

Enter option #6: 11

Enter option #7: 20

Enter option #8: 25

Enter ring she wants: 25

Suppose, your friend is building an automated car called “Besla”. He needs to fix the programming of the car so that it runs at a proper speed. Now, write a python program that takes 2 inputs (distance in meters and time in seconds). The program should then print the velocity in kilometers per hour of that car. Also, it should print whether the car is working properly based on the following chart.

Velocity

Information to be printed

Less than 60 km/h

Too slow. Needs more changes.

Between 60 km/h to 90 km/h

Velocity is okay. The car is ready!

Greater than 90 km/h

Too fast. Only a few changes should suffice.
