使用VC6打开考生文件夹下的源程序文件modi2.cpp。完成空出的函数fun(int a[],int*index),使函数输入n(<100)个整数到指定数组,求该数组中最大元素的值和此元素的下标,最大元素值以函数值返回,此元素的下标通过指针形参带回调用函数。要求函数实现以下的功能:(1)获得输入的n个整数;(2)把最大的数字的下标在...
使用VC6打开考生文件夹下的源程序文件modi2.cpp。阅读下列函数说明和代码,完成空出部分的程序。函数func(int A[NUM],int n)实现的功能是将数组的内容进行一次重新排序。排序的方法是:给定n,则下标为i的数字与下标为n-i的数字交换。从0开始,交换N/2次,则最后的内容为排序后的结果。如果:A[8]={1,2,3,4...
In this code, we can observe how multiple function calls are connected. Now, let’s take a look at the addTwoInts function. This function simply adds these two integers together and returns the result. Moving on to the main function, this is where the action happens. We have a series ...

使用VC++6.0打开考生文件夹下的源程序文件2.cpp,请实现函数fun(double a[],int len)的如下功能: (1)a[]是一个数组,长度为len。 (2)a[0]=0,a[1]=1。 (3)a[i+2]=a[i]+a[i+1]。 注意:不能修改函数的其他部分。 试题程序: #include<iostream> void fun(double a[],int len) void main(...
By default, the MSVC compiler treats all files that end in .c as C source code, and all files that end in .cpp as C++ source code. To force the compiler to treat all files as C no matter the file name extension, use the /TC compiler option. By default, MSVC is compatible with ...
