I have an array in my output that depending on my input might be empty, so in that case I want to print "empty" but I don't know how to write the if condition

What I have tried:

for (int i = 0; i<cnt;i++){
    if (locate[i]='\0'){
        cout << ""<<endl;

    }
    else
    {
        cout << locate[i] +1<<" ";
    }

In my opinion, the easiest way would be to use a flag :

C++

bool empty = true;
for( int i = 0; i < cnt; ++i )
{
    if( locate[i] != '\0' )     // probably want a comparison here
    {
         empty = false;
         cout << locate[i] +1<<" ";
    }
}
if( empty )
{
    cout << "locate is empty" << nl;
}
