Well here is a longish(but easy) solution that does not use pointers. It can be optimized further but hey it works.

#include 
#include 
using namespace std;
void removeExtraSpace(string str);
int main(){
    string s;
    cout << "Enter a string with extra spaces: ";
    getline(cin, s);
    removeExtraSpace(s);
    return 0;
}
void removeExtraSpace(string str){
    int len = str.size();
    if(len==0){
        cout << "Simplified String: " << endl;
        cout << "I would appreciate it if you could enter more than 0 characters. " << endl;
        return;
    }
    char ch1[len];
    char ch2[len];
    //Placing characters of str in ch1[]
    for(int i=0; i
