Reverse a String With the for Loop in C# The for loop iterates through a specific section of code for a fixed amount of times in C#. We can use a for loop to reverse the contents of a string variable. See the below example code. using System; namespace reverse_string { class Program...
In this C++ tutorial, you will learn how to reverse a string using reverse() function, or looping statement, with examples. C++ String Reverse You can reverse a string in C++ either by using available reverse() builtin function, or you can write your own logic using looping techniques. 1....
7.2 push_back和append 那reverse搞好了,我们就可以继续实现push_back()和append()了: 那在判断之后,需要扩容我们就扩容,然后我们插入数据就行了: 那push_back()我们这里就选择扩两倍。 另外给大家提一下我们这里选择用strcpy而没有用strcat,这里不推荐使用strcat,当然strcat也是可以完成的。 那为什么不推荐呢? 因...
