This project includes a function in the C programming language that receives user input with a timeout.
To run this code, first compile it:
gcc main.c -o main
char* remove_last_character(char* str)
: This function removes the last character of a string.char* add_character_to_end(char* str, char character)
: This function adds a character to the end of a string.char* input_with_timeout(const char* prompt, const unsigned int timeout)
: This function receives user input with a timeout.
- After using the pointer returned by the function
input_with_timeout
, make sure to free the allocated memory usingfree()
to avoid memory leaks !
Note
This code includes functions that manipulate strings in C. It's important to understand how memory allocation works in C before using these functions.
Warning
This code uses the malloc
function to allocate memory and the free
function to deallocate memory. Always ensure that you have freed any memory that you have allocated to prevent memory leaks.
Tip
The input_with_timeout
function allows you to set a timeout for user input. This can be useful in scenarios where your program needs to continue executing if the user does not provide input within a certain timeframe.
Important
The remove_last_character
and add_character_to_end
functions modify the original string. If you need to keep the original string unchanged, make sure to create a copy of the string before using these functions.
char *input = input_with_timeout("Enter your input: ", 20);
if (input != NULL) {
printf("Input received: '%s'.\n", input);
free(input);
} else {
printf("Timeout occurred. Returning NULL.\n");
}
