Your logic seems to be okay. The problem is with the declaration of the 1D and 3D arrays. 1) There id no datatype as byte in C 2) new is not a part of C. You cannot allocate memory using new Try the following changes for your code to work int main() { int x; … Read more
I have no idea what half of your code means, but here is your solution. I don’t understand why you have a while loop after main? Many other “Why’s?” , but here is the code: #include<iostream> #include<string> #include<sstream> using namespace std; int main() { string input = “”; int number = 0; while (true) { … Read more
Use rb (read binary) as mode parameter in the fopen() function. For more information: http://www.cplusplus.com/reference/cstdio/fopen/ solved C, read a binary file?
given this code: void matr(int arr[max][max], int n, int m) { int i; int k; for (i = 0, k = m * n; i < k; i++) { arr[i / m][i % m] = rand() % 10 * (pow(-1, rand() % 10)); } } here is an explanation: 1) MAX must be a #define … Read more
OK, I will try to explain this as simply as I can. When you do: putchar(*pch++) what you say is ‘print that character of the address that pch points to and then increment the pch to point to the next address’. Essentially, before the first putchar(), *pch=”a” and after *pch=”b”(because pch points now to ch[1]). … Read more
make it into an ‘out’ parameter and all should be well: private void x() { string sTestFile = “this is a test”; string[] TestFileWords; FixConcatString(sTestFile, out TestFileWords); } private void FixConcatString(string splayfile, **out** string[] sWordArray) { char[] charSeparators = new char[] { ‘-‘ }; splayfile = splayfile.ToLower(); splayfile = splayfile.Replace(@”\”, ” “); sWordArray = splayfile.Split(charSeparators, … Read more
You are kind of not using if else if else correctly. You want to test for each letter grade appropriately. Each test for the grade is a if => else if.. If you don’t get an A, do you get a B? Do you get a C? Do you get a D, or do you … Read more
In your array declaration and definition of calc_comp_total, Salesman has not yet been defined, nor declared. The simple fix is to move the definition of Salesman above those constructs. However, you might be better off defining it in a header file, then including that in your implementation file. 2 solved C++ errors when structures not … Read more
In your function definition float remainingAngle(float answer) the function remainingAngle() accepts one parameter. OTOH, in your function call remainingAngle(angleA,angleB); you’re passing two arguments. The supplied argument number and type should match with the parameter list in function definition. That said, your code is wrong. Point 1. Your local variables will shadow the global ones. Maybe … Read more
Try this way: Dim stringData As String = GetFolderPath(SpecialFolder.MyDocuments) & “\my.exe” ‘For example If Not String.IsNullOrEmpty(stringData) Then If File.Exists(stringData) Then Process.Start(stringData) Else MsgBox(“File couldn’t be found.”, vbCritical, “MyApp”) End If End If solved File.Exists is working in C#, but doesn’t work in VB.NET
You haven’t actually provided code that exhibits your problem but, to answer your question, ways to pass argv[2] as a string to a function include #include <cstring> #include <iostream> void func(const char *s) { // treat s as a zero terminated string if (std::strcmp(s, “Hello”) == 0) { std::cout << “You said hello\n”; } } … Read more
From wikipedia: C# is a multi-paradigm programming language encompassing strong typing, imperative, declarative, functional, generic, object-oriented (class-based), and component-oriented programming disciplines So, in general, we can just use whichever paradigm suits our needs for the task at hand. UPDATE: A couple of caveats have been highlighted by the comments below: It is primarly intended to … Read more
Here s will be “3xzy1” as s[2]=’x’+2; makes s[2] equal to ‘z’, where ‘z’ is a character, not a string. ‘x’-1==’w’; ‘x’+1==’y’; ‘x’+2==’z’ solved C++ sum char and integer
I still prefer using std::vector although this question mentions “without using vector”. But let’s just try doing so with array anyway. int int_array[20] = {/*…*/}; int* last_ptr = std::remove(std::begin(int_array), std::end(int_array), 0); for (int* it = int_array ; it != last_ptr ; ++it) cout << *it << endl; As convention, the resulting last_ptr points to the … Read more
You cannot just change the type of an array. If the first array is a char array, you need to create a new array that would hold integers. Then index by index you need to convert the character from the first array to an integer and then store it in your new array. int intArray[10]; … Read more
