Declare a character array, and initialize it to a suitable string. Use a loop to change every other
character to uppercase.
Hint: In the ASCII character set, values for uppercase characters are 32 less than their lowercase
counterparts.


Please write a string/array program to fulfill this prompt

without using pointer

#include<iostream>
using namespace std;

int main()
{
    char arr[5];
    cin>>arr;
    for(int i=0;i<5;i++)
    {
        arr[i]=arr[i]-32;
    }
    cout<<arr;
    return 0;
}

using pointer

#include<iostream>
using namespace std;

int main()
{
    char* arr;
    int size=0;
    cout<<"\nEnter The Size Of The Char Array : ";
    cin>>size;
    arr=new char[size];
    cout<<"\nEnter The Char Without Going in Next Line : ";
    cin>>arr;
    for(int i=0;i<size;i++)
    {
        arr[i]=arr[i]-32;
    }
    cout<<arr;
    delete[] arr;
    return 0;
}

Enter The Size Of The Char Array : 5

Enter The Char Without Going in Next Line : abcde
ABCDE

OR

#include<iostream>
using namespace std;

int main()
{
    char arr[256];
    int size=0;
    cout<<"\nEnter The Size Of The Char Array : ";
    cin>>size;
    for(int i=0;i<size;i++)
    {
        cin>>arr[i];
    }
    
    for(int i=0;i<size;i++)
    {
        arr[i]=arr[i]-32;
    }
    
    
    for(int i=0;i<size;i++)
    {
        cout<<" "<<arr[i]<<" ";
    }
        
    
    return 0;
}

Enter The Size Of The Char Array : 5
