I have this piece of code that I am trying to exit when the user inputs a number for K, how to i terminate the loop with that number?

for ( int K=0; K<=9; K++)
   {
    cout << "Enter the amount of Calories, Fats, Proteins & Other" << endl;
    cout << "Calories:" << endl;
        cin >> C;
    cout << "Fat:" << endl;
        cin >> F;
    cout << "Protein:" << endl;
        cin >> P;

Since the user do not input anything for K, I fear we can't help you on this.
You need to refine the question with details on what you try to do.

For what I see, the for loop can completely be removed.

The solution given by NotPoliticallyCorrect works with just one extra output, the for statement cannot be taken out because the process needs to loop until the inputted K value is reached, the user does input a K value in the piece of code above the for loop that was not included
