对于C语言的项目,一些文件动辄几千行代码,上百个函数体,理解起来颇有些费劲。这个时候我们可以使用calltree工具对代码进行静态分析,然后产生调用关系树,使得我们可以对代码的构成有个初步的认识。这样可以让我们站在高处,俯览全局,制定出一个着实可行的阅读理解方案。(题外话:静态分析中发生不准确的现象很常见) calltree的
[解析]在main()函数中,首先给一维数组array赋初值[2,2,0,0,0],再调用change函数,对array数组中的每一个数进行减1处理,最后使用一个for循环语句进行输出。 [解析]continue语句只能用在循环结构中,其作用是结束本次循环,即不再执行循环体中continue语句之后的语句,而是立即转入对循环条件的判断与执行。本题执行过...

然后,更改对 placement new 和 delete 的定义,以使用此类型作为第二个自变量(而不是 size_t)。 你还需要更新对 placement new 的调用以传递新类型(例如,通过使用 static_cast<my_type> 从整数值转换)并更新 new 和delete 的定义以强制转换回整数类型。 你无需为此使用 enum;具有 size_t 成员的类类型也将起...
