初心者による初心者のためのC++|製作途中だからどんどん書き加えていくよ

#初心者のためのC++
初めてC++をやるので、間違っていたら教えてください

##標準出力

#include <iostream>

int main()
{
    std::cout << "HELLO WORLD" << std::endl;

    return 0;
}

##コマンドライン引数

#include <iostream>

int main(int argc, char *argv[])
{
	std::cout << argv[1] << std::endl;

	return 0;
}

ファイル名とかがargv[0]になるので、それ以降が引数である

##条件式

OR演算やAND演算をするには、以下のような感じ。

if (<条件1> || <条件2>)
if (<条件1> && <条件2>)

ORには||、ANDには&&を使用する。

##ToUpper

std::toupper(<文字>);
