C++

// Example program
#include <iostream>
#include <string>
using namespace std;

  void findMultiples( int i ,int n){
      int count=0;
  for( i ; i <= n; i++)
    if(i % 3 == 0 ){
    count++;
      cout << i<<"  ";
      if(count==5)
      cout<<endl;
 }
}

int="" main()="" {
="" int="" x;
="" y;
="" cin="">>x>>y;
  findMultiples(x,y);

  return 0;
}

<pre>// Example program
#include <iostream>
#include <string>
using namespace std;

  void findMultiples( int i ,int n){
      int count=0;
  for( i ; i <= n; i++)
    if(i % 3 == 0 ){
    count++;
      cout << i<<"  ";

    }
}

int main() {
    int x;

  findMultiples(x,y);

  return 0;
}

What I have tried:

C++

// Example program
#include <iostream>
#include <string>
using namespace std;

  void findMultiples( int i ,int n){
      int count=0;
  for( i ; i <= n; i++)
    if(i % 3 == 0 ){
    count++;
      cout << i<<"  ";
      if(count==5)
      cout<<endl;
    }
}

int main() {
    int x;
    int y;
    cin>>x>>y;
  findMultiples(x,y);

  return 0;
}

Both of those code samples are C++. What is the Python code that you have produced and what is the problem with it

This is not a code conversion service.

Solution 1

There is nothing complicated in that C code, so it should not take long to convert. See The Python Tutorial — Python 3.7.10 documentation[^] for help.

Solution 2

Well...

I have no idea why do you want to convert C code to Python...

The main rule of CP QA forum is to use Google before you ask a question. So, use it!

I'd suggest to read this:
ctopy(1): quick/dirty C to Python translator) - Linux man page[^]
Calling C Functions from Python - JournalDev[^]

As Richard MacCutchan mentioned, if you understand what above code does, you can write in Python without any converter.

Re "I have no idea why do you want to convert C code to Python":
Here's an idea: One has a code in C and he wants to convert it to Python! :))

Sometimes, it is better to clear understand the requirements and the original source code logic, in order to gain insight.

Sometimes, it is better to understand the requirements and the original source code logic, to perform a good conversion into the target language.

Sometimes, it is better to understand the requirements and the original source code logic, in order to throw that junk away and restart from scratch your program, using the target language.

Python

def find_multiples_of_3_in_range( first, last ):
  if last < first:
    return 0
  frem = first % 3
  lrem = last % 3

  if frem != 0:
   first += (3 - frem)

  last -= lrem

  return (last -first)//3 + 1



def main():
  first = int(input("insert the starting number of the range "))
  last = int(input("insert the last number of the range "))
  multiples = find_multiples_of_3_in_range(first, last)
  print("thre are {} multiples of 3 in the given range".format(multiples))

main()
