Question

write a program that prompts the user to input the length of a string as an integer, followed by the string and outputs the string in uppercase letters using dynamic arrays.

Answer 1

OUTPUT of program :

Enter a string length: 5

Enter a string : hello

String in upper case letters is: HELLO

Enter a string length: 5

WRITE a Program that prompts the length of a string and the string in uppercase letters using dynamic arrays ?

#include <iostream>

#include <cstring>

#include <cctype>

using namespace std;

int main(){

char *str = new char[80];

int *num= new int[80];

char *str1=new char[80];

int len,i;

cout << "Enter a string: "

cin.get(str, 80);

cout << "Enter string length: "

cin.get(num, 80);

cout << "String in upper case letters is:"<< endl;

len = strlen(str);

for (i = 0; i <len; i++)

{

 *(str1+i)=toupper(*(str+i));

}

for(i=0;i<len;i++)

{

 cout<<*(str1+i);  

}

return 0;

}

C++ :

     

           Performance, effectiveness, and flexibility of usage were the design pillars of C++, which was created with systems programming, embedded, resource-constrained software, and big systems in mind. The software infrastructure and resource-constrained applications, such as desktop programmes, video games, servers, and performance-critical programmes, are two areas where C++ has been proven to be very useful.

                      Generic programming is made possible via C++ templates. Function, class, alias, and variable templates are supported in C++. Types, compile-time constants, and other templates can all be used to parameterize templates. At compile time, templates are implemented by instantiation. Compilers use particular inputs in place of a template's parameters to create a concrete instance of a class or function. Some substitutes are not possible, and an overload resolution policy with the motto "Substitution failure is not an error" eliminates these cases (SFINAE).                  

        C++ gives C features for object-oriented programming (OOP). It provides classes that offer the four features frequently found in OOP languages: polymorphism, inheritance, encapsulation, and abstraction. Support for deterministic destructors, which in turn provides support for the Resource Acquisition is Initialization (RAII) idea, sets C++ classes apart from classes in other programming languages.

Answer 2

A random access, variable-size list data structure called a dynamic array, growable array, resizable array, dynamic table, or array list allows elements to be added or removed.

What is dynamic array?

• A random access, variable-size list data structure called a dynamic array, growable array, resizable array, dynamic table, or array list allows elements to be added or removed. It comes with standard libraries for many current, widely used programming languages.
• Similar to a standard array, a dynamic array can have its size changed while the program is running. Each element of a DynamArray takes up a single block of memory. The size of an array cannot be altered once it has been constructed.

#include <iostream>

#include <cstring>

#include <cctype>

using namespace std;

int main(){

char *str = new char[80];

int *num= new int[80];

char *str1=new char[80];

int len,i;

cout << "Enter a string: "

cin.get(str, 80);

cout << "Enter string length: "

cin.get(num, 80);

cout << "String in upper case letters is:"<< endl;

len = strlen(str);

for (i = 0; i <len; i++)

{

*(str1+i)=toupper(*(str+i));

}

for(i=0;i<len;i++)

{

cout<<*(str1+i);  

}

return 0;

}
