    class Program
    {
        static void Main()
        {
            Console.Write("Enter the number of times to print \"Yay!\": ");


            try{
                string numofTimes= Console.ReadLine();
            int num =int.Parse(numofTimes);
                 for(var i=0; i<num; i++){
         Console.WriteLine("\"Yay!\"");
                     break;
            }}
                catch(FormatException){
                Console.WriteLine("You must enter a whole number.");

you don't need the continue or the break. the continue is not in a loop so it is not doing anything. the break is causing the program to end prematurely, before all the yays have been printed. just remove the break and the continue and the code passes tasks 1 and 2.

You don't have a need for a break statement. Your program will end when 'i' hits the ceiling input provided from the user - the second arg in your loop. The reason the compiler complains about 'continue' is because 'continue' can only be implemented within the loop. The program is going to continue regardless. The point of the continue, within a loop, is to avoid execution upon a certain condition. Let's take a look at an example that assumes we're using System; and that the user entered 10 times.

for(var i = 0; i < 10; i++) { 
    //just for fun lets print the 7th iteration as its own thing
    if(i == 6) { 
        Console.WriteLine("I'm " + (i + 1) + " and I'm hungry - I'm going to eat number " + (i + 3) ); 
    } 
    //now lets see the continue statement in action by skipping printing the 9
    else if(i == 8) {
        continue; 
}
    else { 
        Console.WriteLine("iteration: " +  (i + 1)); 
    } 
}

if you were to take out the if( i == 6) line each iteration would print exactly the same except for the number 9. 9 is skipped because of the continue within our conditional.
I hope this helps!!
