如何在多行C/C++中编写长字符串？-yiteyi-C++库

图像的情况下，我们想使用或打印长的长串在C或C++，如何做到这一点？

null

在C/C++中，中间可以用中间的两个双引号断开一个字符串。下面是一个简单的例子来证明这一点。

                     #include<stdio.h>                   
                     int                               main()                   
                     {                   
                                         // We can put two double quotes anywhere in a string                   
                                         char                               *str1  =                               "geeks"                               "quiz"                               ;                   
                             
                                         // We can put space line break between two double quotes                   
                                         char                               *str2  =                               "Qeeks"                               "Quiz"                               ;                   
                                         char                               *str3  =                               "Qeeks"                   
                                         "Quiz"                               ;                   
                             
                                         puts                               (str1);                   
                                         puts                               (str2);                   
                                         puts                               (str3);                   
                             
                                         puts                               (                               "Geeks"                               // Breaking string in multiple lines                   
                                         "forGeeks"                               );                   
                                         return                               0;                   
                     }

下面是几个使用双引号打断长字符串以提高可读性的示例。

                     #include<stdio.h>                   
                     int                               main()                   
                     {                   
                                         char                               *str =                               "These are reserved words in C language are int, float, "                   
                                         "if, else, for, while etc. An Identifier is a sequence of"                   
                                         "letters and digits, but must start with a letter. "                   
                                         "Underscore ( _ ) is treated as a letter. Identifiers are "                   
                                         "case sensitive. Identifiers are used to name variables,"                   
                                         "functions etc."                               ;                   
                                         puts                               (str);                   
                                         return                               0;                   
                     }                   

输出： C语言中的保留字是int、float、if、else、for、while等。标识符是字母和数字的序列，但必须以字母开头。下划线（_）被视为字母。标识符区分大小写。标识符用于命名变量、函数等。

类似地，我们可以用printf和/或cout编写长字符串。

                     #include<stdio.h>                   
                     int                               main()                   
                     {                   
                                         char                               *str =                               "An Identifier is a sequence of"                   
                                         "letters and digits, but must start with a letter. "                   
                                         "Underscore ( _ ) is treated as a letter. Identifiers are "                   
                                         "case sensitive. Identifiers are used to name variables,"                   
                                         "functions etc."                               ;                   
                                         printf                               (                               "These are reserved words in C language are int, float, "                   
                                         "if, else, for, while etc. %s "                               , str);                   
                                         return                               0;                   
                     }
