How to output a string in the C language?

In C language, there are several methods to output strings.

1. The printf function is the most commonly used output function in the C language, and can be used to print strings. For example:

#include <stdio.h>

int main() {
   printf("Hello, World!");
   
   return 0;
}

1. The puts function is used to output strings and automatically adds a new line at the end. For example:

#include <stdio.h>

int main() {
   puts("Hello, World!");
   
   return 0;
}

1. The fputs function is used to output a string to a specified file stream. For example:

#include <stdio.h>

int main() {
   FILE *file = fopen("output.txt", "w");
   if (file != NULL) {
       fputs("Hello, World!", file);
       fclose(file);
   }
   
   return 0;
}

All of these methods can be used to output strings, and the specific method to use depends on your needs.
