// your code goes here
int T,flag=0;
int n;

You Can Try This

#include <math.h>

using namespace std;

int isthisprime(long r){
	if (r==2)
		return 1;
	else if (r==1 || r==0 || r%2==0)
		return 0;
	else
		for (int i=3;i<int(sqrt(r))+1;i+=2)
			if(r%i==0)
				return 0;
	return 1;
}

int main(){
	int a;
	cin >> a;
	while(a--){
		long t;
		cin >> t;
		if(isthisprime(t))
			cout << "Yes" << endl;
		else
			cout << "No" << endl;
	}
}

And Also Please Format You Code Just Surround Your Code With Three (```) At Start And At End
