Explanation:

The difference between c and c++ are given below

(1) C does not support object oriented programming structure while c++ supports object oriented programming structure.

(2) C does not support namespace concept while c++ support namespace concept

(3) C has a procedural language it means it follow top down approach while C++ is object oriented it means it follow bottom up approach

(4) C does not support virtual function concept while C++ support virtual function concept

( 5) The programming structure of c language is given below

#include<stdio.h> // header file

void main() //main method

{

//statement

}

Programming structure of C++

#include<iostream> // header file

using namespace std; // namespace

void main() // main method

{

// statement

}

If anyone know C, will it be not hard to learn C++ because only the syntax will change but the logic of programming is not changed .The operator and most concept are similar in both the languages.

For each of the following application areas state whether or not the tree data structure appears to be a good fit for use as a s

Cerrena [4.2K]

Answer:

a) Chess game moves:- Tree data structure is not a good fit.

b) Public transportation paths:- Tree data structure is not a good fit.

c) Relationshi[p among computer files and folders:- Tree data structure is a good fit.

d) Genealogical information:- Tree data structure is a good fit.

e) Parts of books:- Tree data structure is a good fit.

f) Programming language history:- Tree data structure is not a good fit.

g) Mathematical expression:- Tree data structure is a good fit.

Explanation:

a) Chess game moves:- Tree data structure is not a good fit. Since in tree data structure moving backward or sharing the node is not that much easy. Presume, In chess, you have to check any box is empty or not. Here, Graph is the best fit.

b) Public transportation paths:- Tree data structure is not a good fit. whenever shortest path, routes, broadcast come always graph is a good option. Because in the tree you don't know how many time you visit that node

c) Relationshi[p among computer files and folders:- Tree data structure is a good fit. Since they have a predefined route. Go to 'c' drive. Open a particular folder and open a particular file.

d) Genealogical information:- Tree data structure is a good fit. Since genealogical information also has a predefined route. Here, the Graph is not suitable.

e) Parts of books:- Tree data structure is a good fit. Since manages the chapters and topics are not that much complex. You can see any book index which is in a very pretty format.

f) Programming language history:- Tree data structure is not a good fit. To store the history of the programming language we need some unconditional jumps that's why the tree is not suitable.

g) Mathematical expression:- Tree data structure is a good fit. The tree is suitable in some cases. We have an expression tree for postfix, prefix.

I'm using assembly language. This is my assignment. I kinda confused about how to write code for this assignment. Can anyone exp

Brut [27]

Answer:

oid changeCase (char char_array[], int array_size ) {

__asm{

mov eax, char_array;

mov edi, 0;

readArray:

cmp edi, array_size;

jge exit;

mov ebx, edi;

shl ebx, 2;

mov cl, [eax + ebx];

check:

//working on it

cmp cl, 0x41;

jl next_indx;

cmp cl, 0x7A;

jg next_indx;

cmp cl, 'a';

jl convert_down;

jge convert_up;

convert_down:

or cl, 0x20; //make it lowercase

jmp write;

convert_up:

and cl, 0x20;

jmp write;

write:

mov byte ptr [eax + ebx], cl

next_indx:

inc edi;

exit:

cmp edi, array_size;

jl readArray;

mov char_array, eax;

}

Explanation:

Move char_array to eax as it is base image .
Use ebx as offset .
Use ecx as the storage register .
check if cl is <= than ASCII value 65 (A) .
