Functions

[sme97]

I wrote the below code with functions to print and sort the array from smallest to biggest. The numbers are not being sorted, what could be the reason behind it?

  #include <iostream>
using namespace std;

void arrayPrint(int A[], int n){
	int i=0;
	while(i<n){ 
		cout<< A[i] << " ";
		i=i+1;
	}
}
int arraySmallest (int A[], int start, int end){
	int index=start;
	int i=start;
	while (i<=end){
		if (A[i]<A[index]){
			index=i;
		}
		i=i+1;
	}
	return index;
}
void swap (int x, int y) {
	int temp=x;
	x=y;
	y=temp;
}
void selectionSort (int A[], int n){
	int i=0;
	while(i<n){
		int k = arraySmallest(A,i,n-1);
		swap(A[i],A[k]);
		i=i+1;
	}
}
int main(){
	cout << "Please enter the number of integers" << endl;
	int n;
	int i=0;
	cin >> n;
	cout << "Please enter " << n << " integers" << endl;
	int A[1024];
	while (i<n) {
		cin >> A[i];
		i=i+1;
	}
	cout << "Before Sorting" << endl;
	arrayPrint(A,n);
	selectionSort(A,n);
	cout << "After Sorting" << endl;
	arrayPrint(A,n);





	return 0;
}
