This is my Code C++ for my assignment. Please help me to convert it to C code. Thank you!

What I have tried:

C++

#include<iostream>
using namespace std;
#define N 10

int main()
{
	int array[N],p,q;
	for(int i=0;i<N;i++)
	  array[i]=i;
	cout<<"For instance, given elements are ";
	for(int i=0;i<N;i++)
	  cout<<array[i];
	cout<<endl;
	int r=0;
	while(cin>>p)
	{
	 cin>>q;
	 if(p>=0 && p<N)
   {
   	for(int i=0;i<N;i++)
   	 if(array[i]==p)
   	   array[i]=q;
	  cout<<p<<" "<<q<<"  "<<r++<<"     ";
	  for(int i=0;i<N;i++)
	    cout<<array[i];
	  cout<<"\n";
   }
  }
}

Here is the converted code, using printf and scanf to replace C++'s cout and cin respectively.

C++

#include <stdio.h>

#define N 10

int main()
{
    int array[N], p, q;
    for (int i = 0; i < N; i++)
        array[i] = i;

    printf("For instance, given elements are ");
    for (int i = 0; i < N; i++)
        printf("%d ", array[i]);
    printf("\n");
    int r = 0;
    scanf("%d", &p);
    while (p>0)
    {
        scanf("%d", &q);
        if (p >= 0 && p < N)
        {
            for (int i = 0; i < N; i++)
                if (array[i] == p)
                    array[i] = q;


            printf("\n%d %d\n", p, q);
            for (int i = 0; i < N; i++)
                printf("%d ", array[i]);
            printf("\n");
        }
    }
    return 0;
}

Thanks!

Solution 2

You need to change your I/O code, so use printf and scanf functions.

Tip: visit some tutorial to learn the basics.

It's fairly close to C already, apart from the I/O. No one here will do it for you; you need to research it yourself. But I'll give you a hint. Remove

#include <iostream>
using namespace std;

and replace it with

#include <stdio.h>

Then find some documentation for stdio.h and decide how to fix the things that no longer compile now that iostream is gone.
