C++ While Loops

Make this code stop looping once you get the right answer:

string answer;

bool hasGuessed = false;

while(true) {

cin>> answer;

if (answer == “the right answer”){

__________

}

}

• hasGuessed == false

• hasGussed == true

• hasGuessed = true;

• hasGuessed = false;

Make this code loop three times:

in tries= 0;

while(_________ ) {

cin>> “Looping!”;

tries++;

}

• tries < 3

• answer == 3

• tries > 0

• tries < 0

Make this code stop looping when you get the right answer or have no more tries left

string answer;

int tries = 5;

while(_________) {

cin>> answer;

if (answer == “the right answer”){

cout<<“correct”<<endl;

break;

}

tries - - ;

}

• tries == answer

• tries > 0

• tries >= 3

• tries <= 5

Which of these statements stops a while loop?

• stop;

• break;

• loop pause;

• do { }

Fill in the blank with the right symbol to make this code print Tacos 4 times

int tacos = 4;

while(tacos ___ 0){

cout<<“Tacos”<<endl;

tacos - - ;

}

Fill in the blank to make this code print Go Heat!

3 times

int loop = 0;

while(__________){

cout<<“Go Heat”<<endl;

loop ++ ;

}

• loop < 3

• answer == 3

• loop = 0

• loop == 3

Fill in the blank with the right symbol to make this code print I'm a coder

3 times

int loop = 0;

while(loop __ 3){

cout<<“I'm a coder”<<endl;

loop ++ ;

}

Select all of the statements properly increments an int variable by one?

• variable++;

• variable += 1;

• variable + 1;

• variable = variable * variable;

Select all of the statements properly decrements an int variable by one?

• variable = variable - 1;

• variable -= 1;

• variable - -;

• variable - variable;

• variable - 1;

Which of these represents the best structure for a game loop that has limited tries.

• bool tries = true;

  while( tries == false ) {

  tries = true;

  }

• string tries = "3";

  while( tries == "3" ) {

  tries - -;

  }

• bool tries = true;

  while( tries == true ) {

  cout<<" " <<endl;

  }

• int tries = 3;

  while( tries > 0 ) {

  tries --;

  }
