In your question $arr is the array. First we’ll check if ‘Action’ is in the array. if(in_array(‘Action’,$arr)){ //in_array checks if ‘Action’ is in the array echo “Action is in the array!”; } Now we need to “implode” the array to turn it into a string. echo “(” . implode(‘,’, $arr) . “)”; //implode glues the … Read more
You insert services/prices as another array. So use this and it will be ok: I want to print both result in php In file A $_SESSION[‘cart’][‘prices’][] = ‘1000’; $_SESSION[‘cart’][‘services’][] = ‘game’; In File B $_SESSION[‘cart’][‘prices’][] = ‘2000’; $_SESSION[‘cart’][‘services’][] = ‘game2’; In file C foreach ($_SESSION[‘cart’][‘services’] as $key => $service) { echo $service . ‘ = … Read more
Sui_Q1<- list() is written more than once. it cause the list() to override. The solution is only to put Sui_Q1<- list() and Sui_Q2<-list() before looping. solved R : assigning value in looping and else if
bool equivalent(int a[], int b[], int n) { int i=0, j=0, count=0; // This condition fails immediately because the values are equal while (a[i] != b[j]) { // For this reason neither count nor j are incremented count++; j++; } for (int i=0; i<=n; i++) // This condition succeeds immediately because these values are equal … Read more
You can reduce the objects into a Map by iterating the sources of each object using forEach. You spread the Map’s keys iterator to get the sources array, and spread the values iterator to get the values array: const data = [{“year”:2017,”month”:1,”sources”:{“source1″:50,”source2″:30,”source3”:10}},{“year”:2017,”month”:2,”sources”:{“source1″:50,”source2”:10}},{“year”:2017,”month”:3,”sources”:{“source1″:10,”source2″:10,”source3”:1}}] const sourcesMap = data.reduce((m, { sources }) => { Object.entries(sources).forEach(([key, value]) => m.set(key, … Read more
Change your code to this: String[][] content_split = new String[string_array.length][]; // create 2d array for (int i=0; i<string_array.length; i++){ content_split[i] = string_array[i].split(” : “); // store into array and split by different criteria } Which leaves you with a 2D array of your split content. solved Looping a string split from an array [closed]
Is this what you’re trying to say? If not, please specify how you mean further. This code should give you a number between 1-10 that hasn’t been already used. This code will only work 10 times. Random rnd = new Random(); List<int> usedNumbers = new List<int>(); public int RandomNum(){ int number; do { number = … Read more
Split on “,”. String st = “Tokyo, New York, Amsterdam” String[] arr = st.split(“,”); If st has ‘{‘ and ‘}’. You might want to do something along the lines of… st = st.replace(“{“,””).replace(“}”,””); to get rid of the ‘{‘ and ‘}’. 1 solved How to convert String into String Array in Java? [duplicate]
There are a lot of problem with your code, but at least for me the one the compiler first complains about is: error: cast from pointer to smaller type ‘unsigned int’ loses information │Offset: 4 byte: 0x7ffe4b93ddd4 contents:9 func((unsigned int)(char *)str); I assume that you’re trying to sneak in the literal address of the char … Read more
First, your code is not valid C++. Declaring empty arrays using [] does not exist in C++. So the first thing is to turn this into valid C++ that still preserves what you’re trying to accomplish. One solution is to use std::vector: #include <vector> class Universe { public: std::vector<Star> stars; std::vector<Planet> planets; public: Universe(const std::vector<Star>& … Read more
Write a nested loop to check each element in the array and check it against all the other elements in the array, increment a counter every time you come across the same value. At the end of the inner loop, check if the counter is greater than or equals to 2. If not break the … Read more
In short: you don’t need Nullable<T> or ? in this case at all. string[] is reference type: Console.WriteLine(typeof(string[]).IsValueType); the printed output will be false. So, it can be null without any decoration. Back to your sample. You need to specify setters as well to be able deserialize the given json fragement: public class Settings { … Read more
You can use CSVWriter for this with writeAll() method. It doesn’t work on two dimensional array, but it works with Iterable<String[]> or List<String[]>, so you will need to do conversion first. String[][] table = …; List<String[]> convertedTable = Arrays.asList(table); CSVWriter writer = new CSVWriter(new FileWriter(csvFilename)); writer.writeAll(convertedTable); writer.close(); 2 solved Is there any function to write … Read more
By the suggestions in the comments, partialy @Charles_May ‘s: Simply looping: List<string> Source = {}; //source list List<string> Females = new List<string>(), Males = new List<string>(); foreach (string value in Source) { if (value.ToUpper().Contains(“,F,”)) //Female { Females.Add(value); } else { Males.Add(value); } }//result: both lists are with values That’s it. if you’s like to make … Read more
Point 1: Nested functions are not standard C. They are supported as GCC extension.. Point 2: printf(“&b is:%s\n”,&b); is wrong and invokes UB, because of improper format specifier. You need to change that to printf(“&b is:%p\n”,(void *)&b); Point 3: &(&a) is wrong. the operand for & needs to be an lvalue, not another address, which … Read more
