Pointer just points to the memory cell
Hariyana Grande
i have been studying c since last two months it was going well good untill pointers came in my life
Hariyana Grande
i was happy for loop while loops those sweet things
Ilya
Dont worry. You will understand it in a few weeks

#include <iostream>
using namespace std;
int getTreeCount(double side1, double side2, double distance)
{
double n1, n2;
int count;
n1 = (side1/distance) + 1;
n2 = (side2/distance) + 1;
count = 2* (n1 + n2) - 4;
return count;
}
int main()
{
double side1, side2, distance;
cout << "Enter the length(in meters) and breadth(side 2) of rectangular field: ";
cin >> side1;
cin >> side2;
cout << "Enter the distance between two trees: ";
cin >> distance;
int count = getTreeCount(side1, side2, distance);
cout <<"\nThe count of the trees is that could be planted are: "<<count;
return 0;

how check next value in a valied value with pointer? if ((src+1)) not work [c++]

#include <iostream>
using namespace std;
int getTreeCount(double side1, double side2, double distance)
{
double n1, n2;
int count;
n1 = (side1/distance) + 1;
n2 = (side2/distance) + 1;
count = 2* (n1 + n2) - 4;
return count;
}
int main()
{
double side1, side2, distance;
cout << "Enter the length(in meters) and breadth(side 2) of rectangular field: ";
cin >> side1;
cin >> side2;
cout << "Enter the distance between two trees: ";
cin >> distance;
int count = getTreeCount(side1, side2, distance);
cout <<"\nThe count of the trees is that could be planted are: "<<count;
return 0;
}
simple usage for your code. you can do the rest
scanf("%d", &side1);
printf("\nThe count of the trees is that could be planted are: %d", count);

i see. ill try my best. thanks a lot.
Ilya
If you want value, you need to dereference the pointer by using operator '*'
Ilya
It means you are trying to get the memory that doesnt belong your program
Ilya
Why do you want to get src+1?
Ilya
Show me code

well anyways i tried to redo it

#include <stdio.h>
int treeCount (int len , int wid , int dist);
int main(void){
int len , wid;
int dist;
printf("Input length : ");
scanf("%d", &len);
printf("\nInput width : ");
scanf("%d", &wid);
printf("\nInput distance between trees : ");
scanf("%d" , &dist);
//calling function
treeCount(len , wid , dist);
return 0;

//End of main
int treeCount (int len , int wid , int dist){
int perim = (len + wid)*2;
int tree = perim/ dist;
return printf("\nResult : %d", tree);
}

but there's sth missing
Ilya
\n
Ilya
add this to the text in " "
Ilya
for example "%d\n", &dist
Ilya
no, sorry, i've disoriented you
Ilya
printf("Result: %d\n", tree);
Anonymous
yeah i solved the problem thanks a lot
Hermann
Maybe I can calculate length pointer
Ilya
Pointer for what?
Ilya
Goddamn, dude
Ilya
Why do you need this? Are you iterating over an array or ..?
Anonymous
but you still can do this way
int arr[20];
int *parr = arr;
Welcome to the C bro😂
Do you know what type &arr is?
Ilya
mistake there, you're right.
int *parr = arr;
Just typo.
Fixed.

It's not good
it's "C" and C++ group and he didn't specify which language he wanted, the code that I wrote works for both.

I think object-oriented programming paradigm is also important
