To get the last character of a string, you can use the length of the string minus 1 as the index. For example: String s = "Hello"; char last = s.charAt(s.length() - 1); System.out.println(last); // Outputs 'o' Copy This code gets the length of the string s using the ...
The string class is used to create the strings in Java. The string is an object, which represents a sequence of char values. Java platform provides the String class to create the strings. Java provides various methods to perform the different operations with Strings like "Strings. length()",...
For example, how do we get the last character of a string?my_string = "Challenge!" last_char(my_string) # returns "!"Do all the solutions from above still work? Are there any new solutions? If you know the answer, share it on Twitter! Don’t forget to tag it #RenegadePython. I...
1.gets()函数 gets代表get string,它对于交互式程序比较友好,它从系统的标准输入设备(通常是键盘)获得一个字符串,但是字符串没有预定的长度,它得知道什么时候读取结束,这时候换行符就是停止标志,而回车键就能提供换行符,它会读取换行符之前的所有字符,并添加一个空字符(\0)交给程序。 #include <stdio.h> #defi...
charAt(0); System.out.println("first letter from String: " + sample + " is : " + firstLetter); // Retrieving last character from String char lastLetter = sample.charAt(sample.length() - 1); System.out.println("last letter of String: " + sample + " is : " + lastLetter); /...
In C++,std::string::back()provides a reference to the last character of a string, but this works only for non-empty strings. It can also be used to replace the last character. Syntax: To access the last character: charch=string_name.back(); ...

首先,我们需要导入sys模块,该模块提供了与Python解释器和程序环境相关的函数和变量。在这个问题中,我们使用sys.stdin来获取用户的输入。 importsys 1. 3.2 定义getchar函数 接下来,我们定义一个getchar函数,它将读取用户的输入并返回一个字符。 defgetchar():ch=sys.stdin.read(1)# 从标准输入读取一个字符return...
