Which of the following loops print the numbers from 0 to 5?

• int i=0;

  while (i<5) {

  System.out.println(i);

  i++;}

• int i=0;

  while (i<7) {

  System.out.println(i);

  i++;}

• int i=0;

  while (i<6) {

  System.out.println(i);

  i++;}

• int i=0;

  while (i<=6) {

  System.out.println(i);

  i++;}

Why do we use loops?

• To never end programming

• To show off what you know

• To avoid repeating the same instruction more than one time

• To make it more complex

When given:

int i=0;

while (i<5) {

System.out.println(i);

i++;}

Then i=0; means that

• None

• The first number to be printed is 0

• It is the first natrual number

• That it is a binary number

When given:

int i=0;

while (i<5) {

System.out.println(i);

i++;}

The condition (i<5) means that:

• All of them

• The loop will continue occurring until the value of "i" becomes greater than or equal to 5

• The loop will continue occurring until the value of "i" becomes less than or equal to 5

• The loop will continue occurring indefinitely

When given:

int i=0;

while (i<5) {

System.out.println(i);

i++;}

The instruction i++ means that:

• I every iteration the value of "i" decreases by 2

• I every iteration the value of "i" increases by 1

• I every iteration the value of "i" increases by 2

• I every iteration the value of "i" decreases by 1

When given:

for (int i=0; i<5; i++) {

System.out.println(i);}

Then i=0; means that

• The last value to be printed is 0

• The first value to be printed is 0

• Every time I write a loop I need to make "i" equal to 0

• All of them

When given:

for (int i=0; i<4; i++) {

System.out.println(i);}

The condition (i<4) means that:

• All of them

• The loop will continue occurring until the value of "i" becomes greater than or equal to 4

• The loop will continue occurring until the value of "i" becomes less than or equal to 4

• The loop will continue occurring indefinitely

When given:

for (int i=5; i>0; i--) {

System.out.println(i);}

The instruction i-- means that:

• I every iteration the value of "i" decreases by 2

• I every iteration the value of "i" increases by 1

• I every iteration the value of "i" increases by 2

• I every iteration the value of "i" decreases by 1

Which of the following loops print the numbers from 0 to 5?

• for (int i=0; i<=6; i++) {

  System.out.println(i);

  }

• for (int i=0; i<6; i++) {

  System.out.println(i);

  }

• for (int i=0; i<5; i++) {

  System.out.println(i);

  }

• for (int i=0; i>5; i++) {

  System.out.println(i);

  }
