[ad_1] to prevent func1 from being changed, change it to a const pointer. void func1(const int (*myArray)[3]) { int i, j; int ROWS=3; int COLS=3; for (i=0; i<ROWS; i++) { for (j=0; j<COLS; j++) { // myArray[i][j] =3; //compilation error, is now const cout <<” “<<myArray[i][j]; } } } 2 [ad_2] solved Passing 2D array … Read more
[ad_1] After adding the first element your found is always 1. Reset found to 0 before the next iteration. 2 [ad_2] solved 1D array manipulation iteration using loop and switch statement
[ad_1] You can do the same with Streams: Map<String, String> dic = Files.lines(Paths.get(AlphabetFile)) .map(l -> l.split(“=”)) .collect(Collectors.toMap(s -> s[0].trim(), s -> s[1].trim())); 1 [ad_2] solved Need java equivalent of this c# code [duplicate]
[ad_1] Generate a random integer between 0 and (the array size – 1), both inclusive. Access your array with an index equal to this random number. We can’t give you ready-to-use code unless you show some efforts in terms of your own code. 2 [ad_2] solved How would I print a random array element? [closed]
[ad_1] Based on my understanding you want to check if the type is a list and if the list’s elements is type X. You can do the following: var type = (new List<int>()).GetType(); if (type.GetInterface(“IList”) != null && type.IsGenericType && type.GenericTypeArguments.Length == 1 && type.GenericTypeArguments[0] == typeof(int)) Console.WriteLine(true); //Outputs True 3 [ad_2] solved Item type … Read more
[ad_1] You defined setNumber const, Which means this function will not change any member of the class. Just remove const from function implementation. class ho1 { int number; public: ho1(); void setNumber(int x) { number = x; }; }; [ad_2] solved How fixed function access to the class data member?
[ad_1] The answer is – you really don’t need to be worrying about this at this juncture. If your code is running too slow, then you can experiment with some optimization. However, “too slow” is subjective. Premature Optimization Is The Root Of All Evil. As angelatlarge points out, for the moment – go with what … Read more
[ad_1] Possible fix: #include <stdio.h> int main (void) /* it is better to add void */ { int counter = 0; int sum = 0; /* no average is here */ int grade = 0; int check; for(;;) /* make it to an infinite loop, break later */ { /* put this block inside the … Read more
[ad_1] It adds an event handler to the event Click. When Click event is raised all the handlers method added to it are called. For example: void BtnClickHandler1(object sender, EventArgs e) { MessageBox.Show(“BtnClickHandler1”); } void BtnClickHandler2(object sender, EventArgs e) { MessageBox.Show(“BtnClickHandler2”); } And you add these methods to Click event like this: btn.Click += BtnClickHandler1 … Read more
[ad_1] “Find the items from the model’s property “MenuItems” that has a category name equal to category.name” It is like a filter on the list MenuItems 5 [ad_2] solved What does LINQ query .Where() do?
[ad_1] The OpenFileDialog control has the property Multiselect that will allow you to select multiple files in the same dialog. openFileDialog1.Filter = “Excel files|*.xlsx|All files|*.*”; openFileDialog1.Multiselect = true; Then later you can use the property Filenames (instead of Filename) to retrieve your files: foreach (string filePath in openFileDialog1.FileNames) { // … } Check MSDN for … Read more
[ad_1] Your example is basically equivalent to this: void changeString(string **strPtr) { strPtr = new string*[1]; *strPtr = new string(“hello”); //cout << strPtr[0][0]; } int main() { string *strPtr; changeString(&strPtr); //cout << strPtr[0]; return 0; } And that is basically equivalent to this: void changeString(string *strPtr) { strPtr = new string(“hello”); // Changes the pointer, … Read more
[ad_1] !read.eof() only checks for end of file, not errors reading the file, such as a networked mounted file system not being ready, disk error, or lack of permission to read the file. You should check for all failures, with while(read) which has an overloaded operator to check everything for you. So, if the file … Read more
[ad_1] Lets break pow(payMent = loanAmount * monthlyIntrest / (1 – (1 + monthlyIntrest),-loanDuration)); down a bit. payMent = loanAmount * monthlyIntrest / (1 – (1 + monthlyIntrest),-loanDuration) is one argument. The comma that should split it into two arguments is inside the brackets. Likely you meant payMent = loanAmount * monthlyIntrest / (1 – … Read more
