Answer 1

#include <iostream>
#include <string>
using namespace std;


void removeMultipleBlankSpaces(string text)
{
	int length=text.length();
	int i=0,j=0;
	for(i=0; i<length; i++)
    {
        if(text[0]==' ')
        {
            for(i=0; i<(length-1); i++)
                text[i] = text[i+1];
            text[i] = '\0';
            length--;
            i=-1;
            continue;
        }
        if(text[i]==' ' && text[i+1]==' ')
        {
            for(j=i; j<(length-1); j++)
            {
                text[j] = text[j+1];
            }
            text[j] = '\0';
            length--;
            i--;
        }
    }
	cout<<"\nText without spaces:\n";
	cout<<text<<"\n";
}
 


int main(){
	string* text=new string();
	cout<<"Enter text: ";
	string line;


	while (true) {
		getline(cin, line);
		if (line.empty()) {
			break;
		}
		text->append('\n' + line);
	}
	cout<<"\nCurrent text:\n";
	cout<<text->c_str()<<"\n";
	removeMultipleBlankSpaces(*text);
	
	delete text;
	system("pause");
	return 0;
