How to write long strings in Multi-lines C/C++?

Image a situation where we want to use or print a long long string in C or C++, how to do this? In C/C++, we can break a string at any point in the middle using two double quotes in the middle.

Below is a simple example to demonstrate the same.

C

#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;
}

Output

geeksquiz
QeeksQuiz
QeeksQuiz
GeeksforGeeks

Below are few examples with long long strings broken using two double quotes for better readability.

C

#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;
}

Output

These are reserved words in C language are int, float, if, else, for, while etc. An Identifier is a sequence ofletters and digits, but must start with a letter. Underscore ( _ ) is treated as a letter...

Similarly, we can write long strings in printf and or cout.

C

#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;
}

Output

These are reserved words in C language are int, float, if, else, for, while etc. An Identifier is a sequence ofletters and digits, but must start with a letter. Underscore ( _ ) is treated as a letter...
