In C programming language, the gets() method should be included in the header file <stdio.h>. It is required when the user will have to provide input. It only has one input argument, the variable to hold the data. The user can enter space-separated characters while using the function ...
The gets() function provides no support to prevent buffer overflow if large input string are provided. It is defined in <cstdio> header file. Note: Avoid using the gets() function as it can be dangerous for the program. This function was deprecated in C++11 and removed from C++14. gets...
newline character ('\n'). gets then replaces the newline character with a null character ('\0') before returning the line. In contrast, the fgets function retains the newline character. _getws is a wide-character version of gets; its argument and return value are wide-character strings....
Function Name in Library Does Not Match Function Call NameThe common reasons for the function name in the library not matching the function name you use to call it include the following: The C function name is #defined in a header file to another name that is used in the library. The ...
Returns buffer if successful. A NULL pointer indicates an error or end-of-file condition. Useferrororfeofto determine which one has occurred. Remarks The gets_s function reads a line from the standard input stream stdin and stores it in buffer. The line consists of all characters up to and...
Thegets()function does not perform bounds checking, therefore this function is extremely vulnerable to buffer-overflow attacks. It cannot be used safely (unless the program runs in an environment which restricts what can appear onstdin). For this reason, the function has been deprecated in the ...
In this chapter we will learn all the functions used on strings in C - gets(), fgets(), getline(), getdelim(), getchar(), puts(), putchar(), strlen() in C language.

this function is extremely vulnerable to buffer-overflow attacks. It cannot be used safely (unless the program runs in an environment which restricts what can appear onstdin). For this reason, the function was deprecated in C++11 and removed altogether in C++14.std::fgets()may be used instead...
In contrast, the fgets function retains the newline character. _getws is a wide-character version of gets; its argument and return value are wide-character strings. 重要 Because there is no way to limit the number of characters read by gets, untrusted input can easily cause buffer overruns....
