Compose a c++ function named getspeed that uses a reference parameter variable named speed to accept an integer argument. the function should prompt the user to enter a number in the range of 20 through 70. the value entered by the user should be validated and stored in the parameter variable. set the parameter variable to zero if the user enters a number outside the range of 20 through 70. void getspeed (int & speed) { cout < < “enter a number in the range between 20 and 70” < < endl; cin> > speed; if ( speed < =20 || speed > = 70) speed = 0; }

Awell-diversified portfolio needs about 20-25 stocks from different categories is this true or false?

Suppose s, t, and w are strings that have already been created inside main. write a statement or statements, to be added to main, that will determine if the lengths of the three strings are in order by length, smallest to largest. that is, your code should determine if s is strictly shorter than t, and if t is strictly shorter than w. if these conditions hold your code should print (the boolean value) true. if not, your code should print false. (strictly means: no ties) example: if s, t, and w are "cat", "hats", and "skies" your code should print true - their lengths are 3-4-5; but if s, t, and w are "cats" "shirt", and "trust", then print false - their lengths are 4-5-5 enter your code in the box below
