Tutorial 5 C++

Exercise 1

#include <iostream>

using std::cout;

using std::cin;

int main()

{

int num1;

cout << “Enter a number: “;

cin >> num1;

while (num1– >= 1)

cout << “Countdown:” << num1 << “\n”;

if (num1 <= 1)

cout << “FIRE!”;

}

Exercise 2

#include <iostream>

using std::cout;

using std::cin;

int main()

{

int num1 ;

cout << “Enter a positive number: “;

cin >> num1;

int c = 0;

while (c <= num1)

{

cout << “While Count: ” << c << “\n”;

c++;

}

cout << “\n”;

int b = 0;

do

{

cout << ” Do…While Count : ” << b << “\n”;

b++;

} while (b <= num1);

cout << “\n”;

for (int d = 0; d < num1; d++)

{

cout << “For Count: ” << d + 1 << “\n”;

}

return 0;

}

Exercise 3

#include <random>

#include <chrono>

#include <iostream>

using std::cout;

using std::cin;

int main()

{

int randomnum = random(1, 20);

    int guess = 0;

do

{

cout << “Guess the number:”;

cin >> guess;

if (guess == randomnum)

cout << “Congratulations!”

else if (guess < randomnum)

cout << “Wrong guess!”;

else

cout << “Wrong guess!”;

}while(guess != random)

return 0;

}

Exercise 4

#include <iostream>

using std::cout;

using std::cin;

int main()

{

int x, y, h, w;

cout << “Please enter a x axis: “;

cin >> x;

cout << “Please enter a y axis: “;

cin >> y;

for (h = 1; h <= x; h++)

{

for (w = 1; w <= y; w++)

{

 cout << “X”;

}

cout << “\n”;

}

return 0;
