The Get function has errors when compiling code using gcc/g++ under Linux

The following error occurred when compiling a code named Myfirst.cpp with a g++ in Linux today

myfirst.cpp:In function ' int main () ':
Myfirst.cpp:11:2: Warning: ' char* gets (char*) ' is deprecated (declared at/usr/include/stdio.h:638) [- Wdeprecated-declarations]
Gets (CC);

Collect2:error:ld returned 1 exit status

Careful look at the error message that the Get function is dangerous, specific information please Baidu or Google, but I use Get function only to enter a string of characters, the system can not use, I wrote a

PS: The following operations are done in Linux terminal, the system version is Ubuntu 14.04 LTS

Open Terminal (ctrl+alt+t)

Touch cstdio//Create a file Cstdio, I'm using C + +

Vim cstdio//Edit Cstdio, and add the following content

#include <cstdio>
void Mygets (char *str)
{
int i=0;
scanf ("%c", &str[i]);
while (str[i++]!= ' \ n ')
{
scanf ("%c", &str[i]);
}
str[i-1]=0;//is the default string end in the character array, and the ASCII code for the 0
}

So your own library function is written, I do not know the standard library functions exactly what, but certainly not me, hey

When used, the header file location is added

#include "Cstdio"//is double quotation marks instead of angle brackets

Mygets (str); STR book character array name

You can use the Get function indirectly under Linux.

If you use the C-language notation,

filename of the Cstdio file

Switch

Stdio.h, put the file inside of the

#include <cstdio>

Switch

#include <stdio.h>
