Not satisfying all the test cases

#1

i am unable to find my mistake in this code:

using namespace std;
#include
#include
int main()
{
int n,target;
cin>>n;
int a[n];

for(int i=0;i<n;i++)
cin>>a[i];
cin>>target;

sort(a,a+n);

for(int k=0;k<n-2;k++)
{
	
	int i=k+1,j=n-1;
	while(i<j)
	{
	
		if((a[i]+a[j]+a[k])<target)
		i++;
		
		if((a[i]+a[j]+a[k])>target)
		j--;
		
		if((a[i]+a[j]+a[k])==target)
		{
			cout<<a[k]<<", "<<a[i]<<" and "<<a[j]<<endl;
			i++;
			j--;
		}
	}
}

}

hello Nishchaya,
use if else- if and else otherwise it will do more than one increment / decrement which can voilate i<j condition
