Exchanging values from vectors

[a4ms]

First of all, this is my first post :)

The example is :
consider a vector that has 9 positions where each element (the value of them ) is the next position . (i know its not easy to understand , bare with me)
Position on the vector 1 2 3 4 5 6 7 8 9
Input: 5 7 6 9 2 8 4 0 3
output 5, 2, 7, 4, 9, 3, 6, 8, 0

  #include <stdio.h>

int vetor[9];
int contador = 0;
int i;

void fazercaralho()
{
	for (i = 0; i < 9 ; i++)
	{
		scanf("%d", &vetor[i]);
	}
	for (i = 0 ; i < 9 ; i++)
	{	
		contador = vetor[i] - 1;
		vetor[i + 1]= vetor[contador];
				
	}

	for (i = 0 ; i < 9 ; i++)
	{
		printf("%d",vetor[i]);	
	}



}
int main()
{
	fazercaralho();


}

for (i = 0 ; i < 9 ; i++)
   vetor[i + 1] //out of bounds 

¿what's your question?
I would recommend you to use another array for the result, you are overwritting important data in your code.

Also, limit the scope of your variables and check out parameters

Please add further details

Position on the vector 1 2 3 4 5 6 7 8 9
                Input: 5 7 6 9 2 8 4 0 3
                output 5 2 7 4 9 3 6 8 0

Which operation should transform each value?

Position   current val    new val     operation
   1           5             5           ?
   2           7             2           ?
   3           6             7           ?
   4           9             4           ?
...

Note: shouldn't we refer to positions inside the array by their ‘real’ number, i.e. form 0 to 8 rather than from 1 to 9?
