I am working on a program that is fairly simple. The program simply creates an array of size 5000 and finds a user inputted key using recursion. I completed that part of the program and it works as intended finding any number from 0 – 4999. However I also need to create an error message ..
I’m a beginner C++ learning and I saw the post here. However, it is very unclear for me what is the benefit of dynamic array. One advantage is that one can change the length of a dynamic array, here is the code int *p = new int[10]; // when run out of the memory, we ..
for (int i = 0; i < n; ++i) r[i] = c[i] = 0ll; I saw somewhere written like this but I don’t know exactly what is the reason for doing this. Also later when i am submitting my code without using above loop in my code my output was incorrect. Can somebody explain ? ..
I’m having trouble with adding structures to array in cpp. I’ve came up with this method which works great on ints but when i want to do the same thing on structures im getting error after adding 3 or more. I debugged it a little bit and it seems that delete[] is causing error message ..
So, I’m a beginner learning to code in C++. I’m trying to make a program where you can input the name of a student and then input the grades. After inputting the grades, it will then determine if the student passes or fails using the average. I’ve succeeded in this. The last part is finding ..
The task is to read an integer array from a user and then count sort it. I used vector to take input of the array but it only stops reading integers after I enter non-integer symbol when it has to do it after the last integer. For example, if I enter (5 4 3 2 ..
I have a 2d array like so : char * array[2][2]; I wanted it to store char * So I tried to malloc() using for(i=0:i<2;i++){ for(j=0:j<2;j++) { array[i][j]=(char*)malloc(sizeof(char *)*2); } } After that I stored some elements of char * in the 2d array. The 2d array can print them out.which is fine. I then ..
I am following alone to a YouTube C++ tutorial on creating arrays using loops on Vscode for MacOSx. https://www.youtube.com/watch?v=Z9Wc8EsGjJY This is the for loop I wrote for(;int x=0; x<=8, x++){ The terminal keeps giving me this warning: warning: relational comparison result unused [-Wunused-comparison] for(;int x=0; x<=8, x++){ And as a result my array isn’t printed. ..
I want to add one more value into C++ array, and I have this piece of code: void print_array(int *array, int size) { for (int i = 0; i < size; ++i) { std::cout << array[i] << ‘ ‘; } std::cout << ‘n’; } void add_to_array(int *array, int size, int value) { int *newArr = ..
I’m trying to create a char* toTitleCase function(char* text) that makes every word in a text start with a capital letter. Here is my current code: char* toTitleCase(char* text) { char* arr = new char[strlen(text) + 1]; for (int i = 0; *(text + i) != ‘{$content}’; i++) arr[i] = *(text + i); // Example: ..
