一道程序编译顺序的考题,涉及到函数调用的先后顺序及运算符号的优先级等问题。下面我展开给你讲。
C的程序编译总是从main函数开始的,这道题的重点在“fun((int)fun(a+c,b),a-c)) ”语句。
系统首先要确定最外层 fun()函数的实参,第一个参数的确定需要递归调用fun()函数(不妨称其为内层函数)。内层函数的两个参数分别为x=a+b=2+8=10、y=b=5,执行函数体x+y=10+5=15,于是得外层函数的参数x=15。其另一个参数y=a-c=2-b=-6,再次执行函数体,得最终返回值x+y=15+(-6)=9。 (Compiling together the sequence of test procedures, involving the sequence of function calls and operator symbols, such as the priority problem. Now I give you to start speaking. Procedures for C compiler always start from the main function and at这道题the focus of " fun ((int) fun (a+ c, b), ac)) " statement. System must first determine the most outer layer of fun () function of real parameters, the first parameters of recursive calls required fun () function (may be called the inner function). Inner function separately for the two parameters x = a+ b = 2+8 = 10, y = b = 5, to execute the function body x+ y = 10+5 = 15, then the outer function parameters were x = 15 . Its another parameter y = ac = 2-b =- 6, once again to execute the function body may eventually return the value of x+ y = 15+ (-6) = 9.)

MPC-Design-Using-MATLAB
平时遇到很多做MPC(模型预测控制)研究的额朋友,对MPC的学习遇到不少困难,很大的原因就是有价值的资料很少,国内尤甚。这是本极好的讲解利用Matlab对模型预测控制进行建模分析的国外书籍,书名为Model Predictive Control System Design and Implementation Using MATLAB。在这里把电子版于大家一起共享,希望对研究这块的朋友有帮助。(Usually encountered do a lot of MPC (model predictive control) study the amount of friends, learning the MPC encountered many difficulties, much of the reason is that little valuable information, domestic, especially. This excellent explanation of the use of the Matlab model predictive control modeling analysis of foreign books, the title of Model Predictive Control System Design and Implementation Using MATLAB. The electronic version in here together to share research piece of the friends.)
