puts() prototype
int puts(const char *str);
The puts() function takes a null-terminated string str as its argument and writes it to stdout. The terminating null character '\0' is not written but it adds a newline character '\n' after writing the string.
The main difference between fputs() and puts() is the puts() function appends a newline character to the output, while fputs() function does not.
It is defined in <cstdio> header file.
puts() Parameters
str: The string to be written.
puts() Return value
On success, the puts() function returns a non-negative integer. On failure it returns EOF and sets the error indicator on stdout.
Example: How puts() function works
#include <cstdio>
int main()
{
char str1[] = "Happy New Year";
char str2[] = "Happy Birthday";
puts(str1);
/* Printed on new line since '/n' is added */
puts(str2);
return 0;
}
When you run the program, the output will be:
Happy New Year Happy Birthday
