jslvtr / regex.cpp

Last active December 28, 2015 21:19

This is a way to get 3 words of a line that are space separated, sometimes with multiple spaces, written in C++.

	std::string text = "Hello sweet world"
	// Create cmatch object to match `match_results` objects into string literals
	std::cmatch matchStore;
	// Create a regex object to contain the strings that are going to be matched against
	std::regex reg("([A-z]+)[\\s]+([A-z]+)[\\s]+([A-z]+)");
	// `regex_search` will go through the string and store any matchings into `cm`
	std::regex_search(text.c_str(), matchStore, reg);

This is a way to get three parts out of a line, showing the output, written in C++.

	std::string text = "Hello sweet world"
	// Create cmatch object to match `match_results` objects into string literals
	std::cmatch matchStore;
	// Create a regex object to contain the strings that are going to be matched against
	std::regex reg("([A-z]+)[\\s]+([A-z]+)[\\s]+([A-z]+)");
	// `regex_search` will go through the string and store any matchings into `cm`
	std::regex_search(text.c_str(), matchStore, reg);

	for(int i = 1; i < matchStore.size(); i++) {
	std::cout << "[" << matchStore[i] << "]" << std::endl;

jslvtr / multtwo.asm

Created November 25, 2013 20:22

This SSEM Assembly program multiplies 750 by 2, getting the result 1500.

	; THIS PROGRAM MULTIPLIES A NUMBER BY 2
	; Made by Jose Salvatierra
	; University of Dundee
	VAR 0 ; Fill space
	START: LDN NUM1 ; Copy variable negated
	SUB NUM1 ; Subtract itself (multiply by 2)
	STO MYSUM ; Store it in accumulator
	LDN MYSUM ; Negate the answer (make it positive)
	STO MYSUM ; Store to variable
	STP ; Stop the processor

jslvtr / mult_two.asm

Created December 23, 2013 12:26

This is a thoroughly-commented piece of ASSEMBLY code.

	; THIS PROGRAM MULTIPLIES A NUMBER BY 2
	; Made by Jose Salvatierra
	; For a further explanation go to
	START: LDN NUM1 ; Copy variable negated into the accumulator (this is the value we are working with in the processor)
	SUB NUM1 ; Subtract from the value in the accumulator the value of NUM1 (this is essentially multiplying by 2)
	STO MYSUM ; Store to variable (copy the value we're working with to the variable MYSUM)
	LDN MYSUM ; Get the value of the variable multiplied by -1 (negated) into the accumulator
	STO MYSUM ; Store to variable (copy the value we're working with to the variable MYSUM)
	STP ; Stop the processor (ends the program)
	NUM1: VAR 750 ; Declare 32-bit variable with value 750
