Last active November 16, 2017 20:53
A program in C Language which uses two parameters as input and returns the result of any one of the four basic math operations. This is decided with a char and a function pointer is returned to be used in the main function.
#include <stdio.h>
typedef float (*pt2Func)(float, float);
float Plus (float a, float b) { return a+b; }
float Minus (float a, float b) { return a-b; }
float Multiply (float a, float b) { return a*b; }
float Divide (float a, float b) { return a/b; }
pt2Func GetPtr2 (const char opCode)

Generate ssh key with nice comment, no password and default place.
# Linux
ssh-keygen -t rsa -b 4096 -C "$USER@$(uname -n).$(cut -f 1 -d ' ' /etc/issue | head -n 1 | sed -e 's/\(.*\)/\L\1/')" -N '' -f /home/$USER/.ssh/id_rsa
# Mac OS
ssh-keygen -t rsa -b 4096 -C "$USER@$(uname -n).$(sw_vers | head -1 | cut -c 14-19)" -N '' -f /Users/$USER/.ssh/id_rsa

mfurquimdev / example-r-markdown.rmd
Last active August 29, 2015 14:19 — forked from jeromyanglim/example-r-markdown.rmd
This post examines the features of [R Markdown](http://www.rstudio.org/docs/authoring/using_markdown)
using [knitr](http://yihui.name/knitr/) in Rstudio 0.96.
This combination of tools provides an exciting improvement in usability for
[reproducible analysis](http://stats.stackexchange.com/a/15006/183).
Specifically, this post
(1) discusses getting started with R Markdown and `knitr` in Rstudio 0.96;
(2) provides a basic example of producing console output and plots using R Markdown;
(3) highlights several code chunk options such as caching and controlling how input and output is displayed;
(4) demonstrates use of standard Markdown notation as well as the extended features of formulas and tables; and
(5) discusses the implications of R Markdown.
