Instantiate your AnimalList class somewhere(for example in main method) and then add the instances of an Animal class. for example: var animals = new AnimalList(); animals.Add(new Animal() { Name = “”, Type = “”, Gender = “”}); 2 solved C# Class Add ID from one class to another
A quick test shows that setting @jdweng’s purely LINQ solution 1X, a solution somewhat abusing LINQ to do indexing comes in at 7.4X and a solution using for comes in at 28.4X. (Ab)using LINQ with indexing: var c = Enumerable.Range(0, source[0].Length).Select(chpos => Enumerable.Range(0, source.Length).Select(si => source[si][chpos]).Join()).ToArray(); Using nested for loops: var sourcelen = source.Length; var … Read more
You’re issue seems to be misunderstanding how strtok works. Have a look at this. #include <string.h> #include <stdio.h> int main() { int i, j; char delims[] = ” ,”; char str[] = “1-5,6,7”; char *tok; char tmp[256]; int rstart, rend; tok = strtok(str, delims); while(tok != NULL) { for(i = 0; i < strlen(tok); ++i) … Read more
Either std::fill(dp[0], dp[0] + 165 * 2, -1.0); or std::fill_n(dp[0], 165 * 2, -1.0); should work in standard C++. The error about fill macro with two arguments suggests that something #defines a macro named fill that interferes with the C++ standard library, though. This is likely to break more things than just this, so you … Read more
In C, static is the primary way of “hiding” implementation details. Marking a function or a variable static in C means restricting its visibility to the translation unit in which it is defined. Essentially, only functions inside the same C file can refer to them. Functions from other files or libraries have no way of … Read more
myst1r is an array of char that holds a copy of its initializer. mystr is a pointer to char that points to its initializer. In both cases, the initializer is a literal string. The difference is that you can modify the contents of an array, but you cannot modify the contents of a literal string. … Read more
Would make sense if you knew a li’l bit about awk. Anyways what happens here is that the * is replaced by the numbers you’ve given (-5 and 4 respectively), which means printf(“%*.*s”,-5, 4, s+3); would change to printf(“%-5.4s”, s+3); 0 solved Need to understand printf functioning deeply
There is no question here but I am assuming you want to serialize that json string into an object? Also I would at least post what you have tried and what errors you are receiving if any. This is per the JSON.net web site found here http://james.newtonking.com/pages/json-net.aspx string json = “<you json string>”; JObject o … Read more
your supposed to create an array of intigers and pass it to the average function, and need to pass the size(so that you know how many times to loop). In the loop in your Average function add all the values to a temporary value, then divide by the count input-ed to the function. //returns the … Read more
case 10: verifyValue(value); // the rest of code part 1 break; verifyValue() function is called and after returning from that function // the rest of code part 1 is executed. After that break is executed so you get out of switch construct. Later the control is returned to main() and // the rest of code … Read more
I would do something like: create a map to hold the data read in a pair For i = pair.first to pair.second ++map[i] if there are more pairs, repeat from 2 Find the element in the map with the largest count. The key for that element is the year. In theory, you could use a … Read more
#define int int* will replace int *p, q as int* *p, q. So Here p is double pointer to int and q is of type int. For example consider the below program of your same logic in char #include<stdio.h> #define char char* main() { char *p,q; printf(“%d, %d\n”, sizeof(p), sizeof(q)); } Output is 4, 1 … Read more
You have Jagged Array return type and you need to return two dimensional Rrectangular Array, You can return two dimensional array like this. public String[,] GetAllItems() { //your code String[,] xx = new String[arrayZise,2]; //your code return xx; } 1 solved String Array type method return type error [closed]
This syntax in invalid. You cannot simply write code inside a class definition. Instead, you can write a function and your code will work inside it: class Foo { public: void bar() { int * p = new int; *p = 5; } }; int main(int argc, char ** argv) { Foo f; f.bar(); } … Read more
Do something like below : double a = 5, b = 25; short count = 0; for (double i = a; i <= b; i++) { double sqrut=sqrt(i); if ((int)(sqrut) == sqrut) { printf(“Perfect square %.0f found\n”, i); count++; } } printf(“Total number of perfect squares is %d\n”, count); or like below : double a … Read more
