Spring 2021 c++: hw-5

Create a OOP that counts the number of times a particular letter shows up in the word search. Count how many times it came in the string. Use Inheritance.

Examples

letterCounter([
  ["D", "E", "Y", "H", "A", "D"],
  ["C", "B", "Z", "Y", "J", "K"],
  ["D", "B", "C", "A", "M", "N"],
  ["F", "G", "G", "R", "S", "R"],
  ["V", "X", "H", "A", "S", "S"]
], "D") ➞ 3

// "D" shows up 3 times: twice in the first row, once in the third row.

letterCounter([
  ["D", "E", "Y", "H", "A", "D"],
  ["C", "B", "Z", "Y", "J", "K"],
  ["D", "B", "C", "A", "M", "N"],
  ["F", "G", "G", "R", "S", "R"],
  ["V", "X", "H", "A", "S", "S"]
], "H") ➞ 2

C++ OOP to display name and age


You have to read name and age of a person and display them on the output screen. Here, you will learn how to read string (name) with spaces in C++ language?

Here, you have to  declare a string (character array) variable named name that will store name of the person and integer variable named age that will store the age of the person.

Use Constructor, Destructor and Method in C++

Spring 2021 C++ : hw-2

1. Write a OOP to read string using cin function in c ++ . Count the number of character in that string without using built-in function.

2. Write a OOP to read a line of string using getline() function in c++. Count the number of word and number of character from that string.

1.       The Farming Problem:

In this problem, a person is asking you to tell him how many legs can be counted among all his animals. The farmer has given three types sample:

A.)   Chicken: 2 legs

B.)    Cows: 4 legs

C.)    Goat : 4 legs

The farmer has counted his animals and he gives you a subtotal for each sample. You have to implement a function in OOP that returns the total number of legs of all the animals.

Rules: Don’t for get to return the result. Remember that the farmer wants to now the total number of legs and not the total number of animals.

Hints:

Farmer said that total number of animals is: 150

Farmer mentioned that there are 100 chickens, 25 cows and 25 goats

How to find the smallest string in C++

Write a function  min that has three C string parameters and returns the smallest.

Solution
char* min(char* a, char* b, char* c)
{
    return strcmp(a,b) < 0 ? strcmp(a,c) < 0 ? a : c : strcmp(b,c) < 0 ? b : c;

switch statement in c++

Question
In the Mapple Leaf School System, children are classified by age as follows:
less than 2, ineligible
2, toddler
3-5, early childhood
6-7, young reader
8-10, elementary
11 and 12, middle
13, impossible
14-16, high school
17-18, scholar
greater than 18, ineligible

Given an int variable  age , write a switch statement that prints out the appropriate label from the above list based on  age.

Solution
switch (age)
{
    case 0:
    case 1:
        cout << "ineligible";
        break;
    case 2:
        cout << "toddler";
        break;
    case 3:
    case 4:
    case 5:
        cout << "early childhood";
        break;
    case 6:
    case 7:
        cout << "young reader";
        break;
    case 8:
    case 9:
    case 10:
        cout << "elementary";
        break;
    case 11:
    case 12:
        cout << "middle";
        break;
    case 13:
        cout << "impossible";
        break;
case 14:
case 15:
case 16:
        cout << "high school";
        break;
case 17:
case 18:
        cout << "scholar";
        break;
default:
        cout << "ineligible";

how to compare char in c++

Assume that c is a char variable that has been declared and already given a value. Write an expression whose value is true if and only if c is NOT what is called a white space character (that is a space or a tab or a newline-- none of which result in ink being printed on paper).

Solution
(c==' ' || c=='\t' || c=='\n') ? false : true

calculate total= 1*1*1 + 2*2*2 + 3*3*3 + 4*4*4 using c++

Given an  int variable  n that has been initialized to a positive value and, in addition,  int variables  k and  total that have already been declared, use a  do...while loop to compute the sum of the cubes of the first  n whole numbers, and store this value in  total . Thus if  n equals 4, your code should put 1*1*1 + 2*2*2 + 3*3*3 + 4*4*4 into  total . Use no variables other than  n ,  k , and  total .

Solution
total=0;
k=0;
do
{
    total+=k*k*k;
    k++;
}
while (k<=n);

letter with loop c++

Write a loop that displays all possible combinations of two letters where the letters are 'a', or 'b', or 'c', or 'd', or 'e'. The combinations should be displayed in ascending alphabetical order:

aa
ab
ac
ad
ae
ba
bb
...
ee

Solution:

for (char outerChar='a'; outerChar<='e'; outerChar++)
    for (char innerChar='a'; innerChar<='e'; innerChar++)
        cout << outerChar << innerChar << "\n";
