标签：blog ram 单行注释 idt dom library cti 为什么 ice
1.单行注释一般放在语句的上方：
// cout and endl live in the iostream library std::cout << "Hello world!" << std::endl;
2.多行注释写法：
/* This is a multi-line comment. * the matching asterisks to the left * can make this easier to read */
3.注释的用处
.At the library, program, or function level, describe what
.Inside the library, program, or function, describe how
.At the statement level, describe why
通俗点就是：
（1）描述该块代码是什么；
（2）描述该块代码如何实现；
（3）描述该块代码为什么要如此实现；
接下来举些例子：
(1)what
// This program calculate the student‘s final grade based on his test and homework scores.
(2)how
/* To calculate the final grade, we sum all the weighted midterm and homework scores and then divide by the number of scores to assign a percentage. This percentage is used to calculate a letter grade. */ // To generate a random item, we‘re going to do the following: // 1) Put all of the items of the desired rarity on a list // 2) Calculate a probability for each item based on level and weight factor // 3) Choose a random number // 4) Figure out which item that
(3)why
// We need to divide items by 2 here because they are bought in pairs cost = items / 2 * storePrice;
