To pass literal string to a function, it must have a parameter of type char const *, not char *. So your constructor should have this prototype: Etudiant(char const * c, unsigned int, Date &); Saying the above, you also do not allocate enough memory to copy a string in your constructor. This line: this->name … Read more
In order to access the elements that you have entered into an array you have to indicate the index (position) where the element is. For example, if you have an array with three elements (10, 11 and 12) like this one: int[3] array; //<– Important that this line is outside the while loop int i … Read more
The basic plan, when you need a recursive solution, is to look for a way to break down the problem so that it contains a smaller problem (or more than one smaller problem) that looks just like the original problem, only smaller. For a 2-D array, this can be tricky. Say your array looks like … Read more
#include <stdio.h> int main(){ int arr[] = {12,3,4,23,5,46,5,6,7,78,67,68,134,45,46,47,67,11,23,18,-3}; int count = 21; int i; int pos=0, len=0; for(i=0;i<count-1;++i){//i<count-1-len int k; for(k=0;arr[i+k]<arr[i+k+1];++k) ; if(k>len){ len = k; pos = i; } i += k; } printf(“Longest series: “); for(i=pos;i<=pos+len;++i) printf(“%d “, arr[i]); printf(“\n”); return 0; } solved what is the algorithm for function that check how … Read more
newarray is an automatic local variable. It will no longer exists once function return. Returning pointer to an automatic local variable invoke undefined behaviour and in this case nothing good can be expected. You can allocate memory diynamically and then return pointer to it int *newArray = malloc(sizeof(int)*size); 2 solved Returning pointer to array doesn’t … Read more
It depends on how your class looks but this would be a simple example: #include <iostream> using namespace std; class MyClass { int x; public: void setX(int i) { x = i; } int getX() { return x; } }; int main() { MyClass test[4]; int i; for(i=0; i < 4; i++) test[i].setX(i); ` for(i=0; … Read more
The file stdout, which is what printf writes to, is by default line buffered. That means everything you write to it is buffered, i.e. stored in memory, and is flushed (and actually printed) when you print a newline. 2 solved C char array storing a variable [closed]
It’s usually a good idea to explain what you understand, so we don’t have to treat you as though you know nothing. Important note: This code behaves erratically. I’ll discuss that later. The exclusive or operator (^) produces its result by applying the following pattern to the binary representation of the numbers in question: Where … Read more
You can reverse an array like this: public void reverse(Object [] a){ for(int i = 0; i < a.length / 2; i++){ Object temp = a[i]; // swap using temporary storage a[i] = a[a.length – i – 1]; a[a.length – i – 1] = temp; } } It’s worthy to note that it doesn’t matter … Read more

Assuming you realize this is array: NSArray *a = [[NSArray alloc] init]; NSMutableArray *a1 = [[NSMutableArray alloc] init]; for(int i = 1; i < a.count; i++) { [a1 addObject: a[i]]; } 1 solved Saving data in NSDictionary from NSDictionary
Assume the string follows the format <int,string>,…. Please find the pseudo-code below: Loop through the string `str` and { smaller_sign_pos = str.find(‘<‘, prev_pos) entry_comma_pos = str.find(‘,’, smaller_sign_pos+1) greater_sign_pos = str.find(‘>’, entry_comma_pos+1) if (all pos values are not `npos`) { int_value = atoi(str.substr(smaller_sign_pos+1, entry_comma_pos-smaller_sign_pos-1)) str_value = str.substr(entry_comma_pos+1, greater_sign_pos-entry_comma_pos-1) prev_pos = greater_sign_pos+1 append int_value to int array … Read more
You have a couple of choices. You can use sprintf or one of it’s cousins which work like printf or you can use std::ostringstream. snprintf example #include <cstdio> char buffer[100] = “some text already there “; std::snprintf(buffer + strlen(buffer), sizeof(buffer) – strlen(buffer), “%x”, index); . std::ostringstream example #include <sstream> std::string text(“some already existing text “); … Read more
