Which XXX and YYY correctly output the smallest values? Vector user Vals contains integers (which may be positive or negative).

liubo4ka [24]

Answer:

The answer is "minVal - userVals.at(0); /userVals.at(i) < minVal "

Explanation:

In the question, it uses minVal instead of XXX to hold the very first arra(userVal) element, and rather than YYY you choose a conditional statement to check which integer is lower than minVal to index of loop increment. It changes the value of the minVal if the condition is valid. It's completely different if we talk about another situation.

Write multiple if statements. If car_year is 1969 or earlier, print "Few safety features." If 1970 or later, print "Probably has

Kazeer [188]

Answer:

<em>import java.util.Scanner;</em>

<em>public class Hggg {</em>

<em> public static void main (String [] args) {</em>

<em> System.out.println("Enter the car make year");</em>

<em> Scanner in = new Scanner(System.in);</em>

<em> int car_year = in.nextInt();</em>

<em> if (car_year<1969){</em>

<em> System.out.println("Few safety features.");</em>

<em> }</em>

<em> else if (car_year>=1970 && car_year<1990){</em>

<em> System.out.println("Probably has seat belts.");</em>

<em> }</em>

<em> else if (car_year>=1990 && car_year<2000){</em>

<em> System.out.println("Probably has seat belts.");</em>

<em> System.out.println("Probably has antilock brakes.");</em>

<em> }</em>

<em> else if (car_year>=2000){</em>

<em> System.out.println("Probably has seat belts.");</em>

<em> System.out.println("Probably has antilock brakes.");</em>

<em> System.out.println("Probably has airbags.");</em>

<em> }</em>

<em> }</em>

<em> }</em>

Explanation:

In this solution, multiple if statements have been used to accomplish each step. Observe that there are more than one print statements when year is greater than 1990 because the condition applied to year greater than 1970 holds true for every year greater than 1970 (1990, 2000 etc)
