use like this it will help String[] subjects = {}; String[] another = {“Physics”,”Chemistry”}; subjects = another.clone(); or second option do like this subjects = Arrays.copyOf(another , another .length); this will copy your another array into your subjects array 5 solved Replacing String array by another [duplicate]
I went through all the below answers. But none of them produced the solution. The problem in all solution is the array is printed on same cell, leaving the other cell empty(including the answer provided by Vadian – it will give error because it is printing all the value in same row.). While printing an … Read more
The statement a = new arr***[num]; allocate an array of num pointers to pointers to pointers to arr, and make a point to that memory. The type of a have to be arr****. Which is just silly. 0 solved What is the meaning of “a = new arr ***[num];”? [closed]
new is for dynamic allocation (of an array on the heap in this case), and returns a pointer to the new array. [] in the declaration are for declaring it to be a stack array (and the brackets belong the right side of the variable name). So the two legal approaches your code is mixing … Read more
See the code snippet for your understanding: #include <iostream> #include <string> using namespace std; int main() { string name; char arr[10] = { ‘a’, ‘b’, ‘c’, ‘d’, ‘e’, ‘f’, ‘g’, ‘h’, ‘i’, ‘j’ }; bool found_a = false; bool found_b = false; bool found_c = false; for (int x = 0; x < 10; x++) … Read more
I think that you needed string, not 2D-Array. You can be written out to a string like write to the standard output by implementing a string that a simple extension. #include <stdio.h> #include <stdlib.h> #include <string.h> typedef struct char_vec { char *v; size_t capacity; size_t used; } sstream; sstream *ss_new(void); void ss_free(sstream *ss); void ss_putc(sstream … Read more

Why is my ArrayList throwing a “PSCustomObject doesn’t contain a method for ‘foreach’” error when the ArrayList contains <= 1 item, & only in PS 5? solved Why is my ArrayList throwing a “PSCustomObject doesn’t contain a method for ‘foreach’” error when the ArrayList contains
First you need to create a variable to store the difference in minutes. Get the first date as reference and create a collection with it. Then filter the rest of the dates checking if the minute component between the the reference date and the current date are equal to the difference. If true increase the … Read more
i intentionally left the previous answer because understanding memory allocation is trivial in programming in c specially. and as i see you have a big issue with that. but still you have issue in nearly every thing. in my actual answer, i will try to simplify you how to use strtok, to split string and … Read more
As you have a 2-d array, you have two length values for each loop: //you have this? array[][]; for(int i = 0; i < array.length; ++i) { for(int j = 0; j < array[i].length; ++j) { //do something on array[i][j] } } solved Using two for loops to loop through a 2D array in java
To sum the values, you can loop over the data using .items(), will return the key with its associated value at each iteration: s = {‘A’: [3, 4, 7], ‘B’: [4, 9, 9], ‘C’: [3, 4, 5], ‘D’: [2, 2, 6], ‘E’: [6, 7, 9], ‘F’: [2, 4, 5]} new_dict = {} for a, b … Read more

This operator+ is used here (a pointer to single char that is not null-terminated is not really suitable). Yes, most definitely undefined behavior. lhs – string, character, or pointer to the first character in a null-terminated array Just make std::string the common type to fix it: ((d == ‘\0’) ? std::string(“null character”) : std::string(1, d)) … Read more
