Print last character of each word in a string

Given a string str, the task is to print the last character of each word in the string.

Examples:

Input: str = “Geeks for Geeks”
Output: s r s

Input: str = “computer applications”
Output: r s



Approach: Append a space i.e. ” “ at the end of the given string so that the last word in the string is also followed by a space just like all the other words in the string. Now start traversing the string character by character, and print every character which is followed by a space.

Below is the implementation of the above approach:

// CPP implementation of the approach
#include<bits/stdc++.h>
using namespace std;
  
// Function to print the last character
// of each word in the given string
void printLastChar(string str)
{
  
    // Now, last word is also followed by a space
    str = str + " ";
    for (int i = 1; i < str.length(); i++) 
    {
  
        // If current character is a space
        if (str[i] == ' ')
  
            // Then previous character must be
            // the last character of some word
            cout << str[i - 1] << " ";
    }
}
  
// Driver code
int main()
{
    string str = "Geeks for Geeks";
    printLastChar(str);
}
