Let me go ahead and print out a character.

让我继续打印一个字符。

Percent c is going to be the placeholder for printing a single character.

百分比c将成为打印单个字符的占位符。

This is important because if I call a function like " print quote" , which writes the string to the screen, it prints out each character in turn starting at the first memory location, but it needs to know when to stop!

这很重要，因为如果我调用像“print quote”这样的函数，它将字符串写入屏幕，它会从第一个内存位置开始依次打印出每个字符，但它需要知道何时停止！
