Answer 5

// An efficient C++ program to remove all spaces

// from a string

#include <iostream>

using namespace std;

// Function to remove all spaces from a given string

void removeSpaces(char *str)

{

    // To keep track of non-space character count

    int count = 0;

    // Traverse the given string. If current character

    // is not space, then place it at index 'count++'

    for (int i = 0; str[i]; i++)

        if (str[i] != ' ')

            str[count++] = str[i]; // here count is

                                   // incremented

    str[count] = '\0';

}

// Driver program to test above function

int main()

{

    char str[] = "g  eeks   for ge  eeks  ";

    removeSpaces(str);

    cout << str;

    return 0;

}
