计算方法典型算法示例（Typical examples of calculation methods） Appendix / some typical algorithms program examples / / / / all source program files in this annex can be sent to the reader via the e-mail, if you have any questions, or suggestions, welcome to the author e-mail, author of the e-mail address is bxjsyjs@. Readers are requested to indicate the e-mail receiver address. In the following sections / program basically corresponds with the book in front of each chapter, the reader in the relevant chapters after school, do the corresponding practice program. / / in order to ensure the integrity of each program, which can be run separately, there are a lot of duplication of code and the same C function between different procedures in the following sections, especially some of the input / output function. The benefit of this arrangement is that the reader can choose a sample program at will, without having to read anything other than the example program. So, please note that when you enter the program, the same code and the C function can be copied directly between files. / / Section 1 / A is used to calculate the C function for arbitrary mathematical function f (x) and F function (x, y) value / / ///////////////////////////////////////////////////////////////////////////////////////////////////////////////////////// / / any input expression of a mathematical function, the input variable value, calculates the mathematical function of the value of the expression, it will encounter in many cases. For example, the unary function y=2sinx+1, the function value y when seeking x=5; or two yuan function z=3cos (x+1) +y, x=2, y=3 function value Z; or three yuan function q=2x+3y+sin (z+2x), x=1, y=2, z=3 function value Q. Three / / C function under float program f (float x), float f (float x, float y) and float f (float x, float y, float z) were calculated to achieve a function of two yuan and three yuan, the function value of the function (because the three C function of the same nam
