reverse

Question

the question is:
Write and test the following function:
void reverse(int a[],int n);
The function reverses the first n elements of the array. For example, the call reverse(a,5)
would transform the array {22,33,44,55,66,77,88,99} into {66,55,44,33,22,77,88,99}.

my code is:
void reverse(int a[],int n);
int main()
{
int a[8]={22,33,44,55,66,77,88,99};
cout<<"The array is: "<<endl;

for(int i=0; i<8; i++)
{
cout<<a[i]<<",";
}

reverse(a,5);

}

void reverse(int a[],int n)
{
for(int i=0; i<n/2; i++)
{
swap(a[i],a[n-1-i]);
}

cout<<"\nAfter reverse(a,5):";

for(int i=0; i<n; i++)
{
cout<<a[i]<<",";
}

}

why the rest not showing?

Answer 1

There is nothing to be sorry for, buddy!
happy learning ☺️

Answer 2

replace reverse(a,5); with reverse(a,8);

Since you are reversing the array you will be needing all the elements of the array and in your case it's 8 elements and not just 5 elements.

Answer 3

Your function does exactly what it is supposed to do. The only problem is that your output loop doesn't output the whole array. It only goes to n, 5 in the example, but should go up to the length of the array, 8.

Answer 4

yes yes sorry got it now

Answer 5

ok thank you
