I eventually figured this one out. Here’s the code I came up with: /*********************************************************************** * Program: * Assignment 31, Array Design * Sister Unsicker, CS124 * Author: * Lanie Molinar * Summary: * This program gets 10 grades from the user, averages them, and displays * the result. It doesn’t count -1 as a completed … Read more
Change the following statements int ** dp = new int *; *dp = array; Or even you could write one statement instead of the two above int ** dp = new int *( array ); Also do not forget to free the allocated memory delete dp; delete []array; As for your code then you are … Read more
A lowercase -l is a linker option used to specify libraries. They might look like libsomething.a and becomes -lsomething in the linker invocation. In order to add a directory to the header search path, use a capital i, -I. gcc main.c -L/some/path/ffmpeg_build/lib -I/some/path/ffmpeg_build/include 1 solved Compile error when using FFMPEG library
The locally scoped winTemp variable is hiding the instance variable (inside readXML() method). Thus winTemp instance variable does not get set at all and holds the default value, i.e. 0, by the time of addition. solved Evaluating equations during “new EXlement”
Initially you set: int menu_choice = 0; Then you ask: if (menu_choice < 1 || menu_choice > 4 ) The choice is smaller than 1 so the if block is entered. You then get some user input and exit the application. 3 solved Condition is not evaluated in loop
Template: int strcmp ( const char * str1, const char * str2 ); strcmp() compares the C string str1 to the C string str2. 1. return value<0 : the first character that does not match has a lower value in ptr1 than in ptr2. 2. return value=0 the contents of both strings are equal. 3. … Read more
Objects don’t have names – variables have names. When you declare a variable and initialize it (Java): Person alice = new Person(“Alice”, 25); then alice is the name of a variable, not the name of an object. If you need to create objects in a loop and keep track of them, then use an array … Read more
In order for this to work correctly you need to change s to the member variable pointing to the array of characters. You didn’t provide the class definition of String so it’s hard to say what the name of that member variable is. You should also change char String::element(int i) const to either char String::element(size_t … Read more
class Number : public string { public: Number() : string(“0”) { } Number(const string &str) : string(str) { } }; However, as long as you have the following 2 lines in the beginning, the name Number will be replaced by preprocessor. #ifndef Number #define Number You should use another macro name for the #include guard. … Read more
It seems to be a lack of understanding of the ASP.NET page lifecycle. In WPF, the lifecycle spans from when you run the program til when it is closed; it is statefull. ASP.NET is not; whatever you do in a Page_Load (and the other lifecycle events) will be disposed with the completion of rendering the … Read more
behold, LINQ // don’t need to know which is start or end, assuming string compare works as expected. var addresses = new List<string>() { “192.168.10.10”, “192.168.10.20” }; // convert string to a 32 bit int Func<string, int> IpToInt = s => { return ( // declare a working object new List<List<int>>() { // chop the … Read more
In your setMake function it’s declared as a string but returns no value. I believe you forgot to return the passed value. //************ // setMake //************ string Car::setMake(string carMake) { make = carMake; return make; // This line should do the trick } I do suggest next time taking a closer look at what the … Read more
Initialize employeeCounter and it’ll work: int employeeCounter = 0; Frankly, this code simply is not presentable at all. You need to at least indent it consistently. There are a lot of things that you need to look at. You should go through the C++ Core Guidelines. https://github.com/isocpp/CppCoreGuidelines/blob/master/CppCoreGuidelines.md Edited — Updated Code Here’s your cleaned up … Read more
Instead of comparing values pointed to by the pointers in statements like this if (n->me < curr->me) you are comparing pointers themselves. You should rewrite the condition like if ( *n->me < *curr->me ) solved insertion sort using linked list and pointers
