给定字符串 str ，任务是打印字符串中每个单词的最后一个字符。
示例:
输入: str = "极客换极客" 输出: s r s
输入: str = "计算机应用程序" 输出: r s
方法:在给定字符串的末尾添加一个空格，即 " " ，这样字符串中的最后一个单词后面也会跟一个空格，就像字符串中的所有其他单词一样。现在开始逐字符遍历字符串，并打印每个后跟空格的字符。 以下是上述办法的实施情况:
c
// cpp implementation of the approach
#include
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);
}
