C++ <cstdio> - gets() Function

The C++ <cstdio> gets() function reads characters from the standard input stdin and stores them as a C string into str until a newline character is found or end-of-file is reached.

The newline character, if found, is not copied into str. A terminating null character is automatically appended after the characters copied to str.

Syntax

char * gets ( char * str );

Parameters

Return Value

• On success, str is returned, On failure, null pointer is returned.
• If the failure has been caused due to end-of-file condition, additionally sets the end-of-file indicator feof() on stdin.
• If error occurs due to some other reason, additionally sets the error indicator ferror() on stdin.

Example:

  //taking input from keyboard
  printf("Enter full name: ");
  gets(name);

  printf("Your name is: %s\n", name);

  return 0;
}
