C++到底怎么输出"啊

    Google Custom Search API貌似没有C/C++版本，只有Java（好像还有Python），于是我想借助Powershell打开URL
    但是Google Advanced Search中参数是用&连接的，而Powershell中不支持&，所以URL必须用"包括起来
    e.g.

    $ start "https://www.google.com/search?&as_q=c++&as_sitesearch=umr.fun"

    目前我还没加"的代码版本是

    //...
	string cmd = "start https://www.google.com/search?";	//TO DO: add " before and behind URL
//...
	cmd += cfg;
	char * p_cmd = (char *)cmd.data();
	system(p_cmd);	//TO DO: open cli-web-browser instead
//...

    现在的问题是，按照网上的说法，用"输出"的话，第一句应该写成

    	string cmd = "start \"https://www.google.com/search?"

    但是这样VS会把start \赋值给cmd，忽略后面的https...，\并没有起到转义的作用，效果是打开文件所在目录
    所以，到底怎么把这对双引号加上啊...

    另外，我打算借助Google相关API抓取搜索结果的title和URL，直接在命令行显示，不过目前好像没精力做，预期的样子：
