Prototype
char *gets(char *s);
wchar_t *_getws(wchar_t *s); // Unicode version
Description
Gets a string from stdin.
gets collects a string of characters terminated by a new line from the standard input stream stdin and puts it into s. The new line is replaced by a null character (\0) in s.
gets allows input strings to contain certain whitespace characters (spaces, tabs). gets returns when it encounters a new line; everything up to the new line is copied into s.
The gets function is not length-terminated. If the input string is sufficiently large, data can be overwritten and corrupted. The fgets function provides better control of input strings.
Remarque : For Win32 GUI applications, stdin must be redirected.
Return Value
On success, gets returns the string argument s.
On end-of-file or error, it returns NULL
Example
#include <stdio.h>
int main(void)
{
char string[80];
printf("Input a string:");
gets(string);
printf("The string input was: %s\n", string);
return 0;
}
