We will see how to compare two strings, concatenate strings, copy one string to another & perform various string manipulation operations. We can perform such operations using the pre-defined functions of “string.h” header file. In order to use these string functions you must include string.h...
To use string functions in C++ we need to add a library named <string> in our code at the top, which gives you string functions. It must be included with the header file #include <string>. As we know there are many behaviors that string object understands and several operations we can ...
Functionsgets()andputs()are two string functions to take string input from the user and display it respectively as mentioned in theprevious chapter. #include<stdio.h>intmain(){charname[30];printf("Enter name: "); gets(name);//Function to read string from user.printf("Name: ");puts(nam...

在引入fbstring之前,我们首先再回顾一下 string 常见的三种实现方式。 string 常见的三种实现方式 string 中比较重要的 3 个字段: char *data. 指向存放字符串的首地址(在 SSO 的某些实现方案中可能没有此字段)。 size_t size. 字符串长度。 si
