Answer:

int numHouses = 25;

Explanation:

The answer above is the Java and C++ prgramming languages' method of declaring and assinging a value to a variable.

To declare a variable, the variable type is written first , this could be (int for Integer, char for characters, double for decimal numbers, etc.), then followed by the name the programmer chooses to give to the variable which must not be a keyword or reserved word. The equality opereator performs the assignment operation of assigning a value to the variable in this case 25.

int numHouses = 25;

int is the variable type

numHouses is the variable name

= is the assignment operator

25 is the assigned value

torisob [31]

Explanation:

public class Int_List

{

protected int[] list;

protected int numEle = 0;

public Int_List( int size )

{

list = new int[size];

public void add( int value )

{

if ( numEle == list.length )

{

System.out.println( "List is full" );

}

else

{

list[numEle] = value;

numEle++;

}

public String toString()

{

String returnStr = "";

for ( int x = 0; x < numEle; x++ )

{

returnStr += x + ": " + list[x] + "\n";

}

return returnStr;

}

public class Run_List_Test

{

public static void main( String[] args )

{

Int_List myList = new Int_List( 7 );

myList.add( 102 );

myList.add( 51 );

myList.add( 202 );

myList.add( 27 );

System.out.println( myList );

}

Note: Use appropriate keyword when you override "tostring" method

2. Write a program with a function that accepts a string as an argument and returns a copy of the string with the first characte

Oduvanchick [21]

Answer:

Following are the code to this question:

def capital(val):#defining a method that takes string value as parameter

x=True#defining boolean variable

r=''#defining string variable

for i in val:#defining loop to convert the first character into upper case

if i.isalpha() and x:#defining condition to check input value is string

r=r+i.upper()#change value into uppercase and hold value in r variable

x=False#assign value false in boolean variable

elif i=='.' or i=='?' or i=='!':#check symbols

r=r+i#add value in r variable

x=True#assign value True in boolean variable

else:

r=r+i#add all value in r variable

return r#return r variable value

val=input()#input value in val variable

print(capital(val))#called the function which print the return value

Output:

please find the attachment.

Explanation:

In the above python program, a method "capital" is declared, which accepts a "val" a string value in its parameter, and inside the method one boolean "x" and one string "r" variable is used, in which r stores return value.
In the next step, for loop is declared, inside the loop, the conditional statement is used, in if the block it checks string value and converts the first character into upper case and assigns value false in the boolean variable.
In the next step, elif block is defined that adds value in r variable and at the last, it will return function value, at the last step "val" variable is declared that input value from the user and pass into the method and print its return value.

Homework 8 Matlab Write a function called fibonacciMatrix. It should have three inputs, col1, col2, and n. col1 and col2 are ver

Amiraneli [1.4K]

In this exercise we have to use the knowledge in computational language in python to write the following code:

We have the code can be found in the attached image.

So in an easier way we have that the code is:

function v = myfib(n,v)

if nargin==1

v = myfib(n-1,[0,1]);

elseif n>1

v = myfib(n-1,[v,v(end-1)+v(end)]);

end

function v = myfib(n,v)

if nargin==1

v = myfib(n-1,[0,1]);

elseif n>1

v = myfib(n-1,[v,v(end-1)+v(end)]);

elseif n<1

v = 0;

end

function [n] = abcd(x)

if (x == 1 || x==0)

n = x;

return

else

n = abcd(x-1) + abcd(x-2);

end

fibonacci = [0 1];

for i = 1:n-2

fibonacci = [fibonacci fibonacci(end)+fibonacci(end-1)];

end

>> myfib(8)

ans =

0 1 1 2 3 5 8 13

>> myfib(10)

ans =

0 1 1 2 3 5 8 13 21 34
