Answer 1

#include <iostream>
#include <string>

std::string Capitalize(std::string str)
{

    std::string ch = str;
    for (int i = 0; i < ch.length(); i++)
    {
        int k = i;
        while (i < ch.length() && ch[i] != ' ')
            i++;
 
        ch[k] = (char)(ch[k] >= 'a' && ch[k] <= 'z'
                        ? ((int)ch[k] - 32)
                        : (int)ch[k]);
        ch[i - 1] = (char)(ch[i - 1] >= 'a' && ch[i - 1] <= 'z'
                            ? ((int)ch[i - 1] - 32)
                            : (int)ch[i - 1]);
    }
 
    return ch;
}
int main ()
{
    std::string input_string;
    getline(std::cin, input_string);
    input_string = Capitalize(input_string);
    if(input_string.empty())
    {
        std::cout<<"String is empty"<<std::endl;
    }
    std::string word_to_remove;
    getline(std::cin, word_to_remove);
    unsigned long length = word_to_remove.size();
    if (length != std::string::npos)
    {
        input_string.erase(length, word_to_remove.length());
    }
    std::string word_to_insert = "hello";
    input_string.insert(4, word_to_insert);
    std::cout<<input_string<<std::endl;
    input_string = Capitalize(input_string);
    
    
    
    std::cout<<input_string<<std::endl;
}
