#include <iostream>
using namespace std;
int main()
{
	string str;
    cout<<"Enter the string ";
    getline(cin,str);
	int len=str.length();
	char newstr[len];
//Removing one or more blank spaces from string
int i=0,j=0;
while(str[i]!='\0')
{
	while(str[i] == ' ')//using loop to remove consecutive blanks
		i++;
	newstr[j]=str[i]; //newstr[j++]=str[i++] we can also use this instead
	i++;
	j++;
}
newstr[len-1]='\0';//terminating newstr, we use -1, as j was a post increment.
cout&lt;&lt;"\n String after removal of blank spaces is:"&lt;&lt;newstr;
return 0;

}
