C snippet Visual Studio 2019

I am having trouble adding a snippet to VS. All of the tutorials out there are for c# and c++.

Please help.

I want to have a snippet where I press 'C' and then this comes up:

#define _CRT_SECURE_NO_WARNINGS
#include <stdio.h>
int main(void)
{
  return 0;
}

I added an image of the version of VS I have on my laptop
