you can't access the last element of an array by only knowing the array's starting address.

So there is no such way to access for dynamic?

correct - again, you need to know the size and the starting address to access the last element.

What if size is given 10 but array having only 6 elements and also know base adress 1000

the size of the array does not change, no matter how many elements you have in it. If you want to get the last element you put in, you need to keep track of that as well.

Canu help in allocating memory c problem.. I have questions but not getting it

I create a data type using struct and i asked the user how many people data is going to be stored then (int no;) I use for (int i=1;i<no;i++) Cout<<" "; Cin.getline(sol.name,24)[i]; Do i need to include i?

assuming sol is your array / list of persons, you probably want sol[i].name

assuming sol is your array / list of persons, you probably want sol[i].name

Others wont change ? Cin getline(sol[i].name,24);

in this case you change the name of the i-th person

in this case you change the name of the i-th person

#include <iostream> using namespace std; struct eyuel { char name[25]; int age; float weight; }; int main() { int no,i; eyuel sol; cout << "how many Owner files do you want to create? "; cin >> no; for ( i = 1; i <= no; i++) { cout << "Enter The name of the Owner: "; cin.getline(sol[i].name, 24); cout << "\n Enter the age of the Owner: "; cin >> sol[i].age; cout << "\n Enter the weight of the Owner: "; cin >> sol[i].weight; cout << "\n name : " << sol[i].name << "age : " << sol[i].age << "Weight : " << sol[i].weight<< endl; } return 0; }

so what do you sugest

I need a C++ program that will read Fibonacci series plz

read?

can you elaborate on it

I need a C++ program that will read Fibonacci series plz

where is your code? what went wrong?

while executes after checking it

#include <iostream> int main() { int input; while (std::cin >> input, input) { std::cout << "Received input: " << input; } return 0; }

while this might work in your case, it does behave different, only the second condition is checked. e.g. this is an endless loop while(0, 1) {}, while this one never executes while(1, 0) {}

If the code you read is indented like that it is indeed hard to read, try to indent it to make it more readable, add comments on what you understand and work your understanding from there

Okay. Pls copy and paste it in your ide and try if you can indent it to understand the code

I do understand it perfectly, I am trying to help you, not myself

class sumset{ public: sumset(); class sum{ public: friend const sum operator +(sum &obj1,sum &obj2); int get_a(){ return a; } sum(int n1):a(n1){ } private: int a; }; private: sum *arr; }; How can I find sum of two number in nested class using operator + . sumset keeps in private part sum *arr that keeps sum element.(So example in main sumset s1,s2; find s1+s2)

Pls help me with your code

No, best I can do is to give you hints to understand your assignment better

I've tried using the replace library but it's does not work

read the code carefully, play it out on paper, use cppreference.com to check standard library features

@QNeko Dear admin can we ask our test question in this group

You can if you don't say it's your test question...

Are you group admin or moderated I am new IDK

No, but I'm here for 3+ years.

Anybody please answer this I am trying but not getting it

@Tazmikar Now pleasee

#include<stdio.h> int main() { int i; for(i = 100; i <= 300; i++) { if(i%3 == 0 & i%5 == 0) { printf("%d\n",i); } } return 0; }

Seems to work fine... what is the problem?

&&

What happen when we assign a same pointer with different address even it declared earlier?

Print the numbers between 100 to 200 which are completely divisible by 3 and 5.

It worked with single & too...

#include <stdio.h> int main() { for (int i = 100; i <= 200; i++) { if (i % 3 == 0 && i % 5 == 0) { printf("%d\n", i); } } return 0; }

#include <stdio.h> int main() { for (int i = 100; i <= 200; i++) { if (i % 3 == 0 && i % 5 == 0) { printf("%d\n", i); } } return 0; }
