Question 01: write a complete C++ program that should print the result of each of functions the following a. Function name: FindMinElement The function should take 3 integer values and returns the minimum the number. b. Function name: FindMaxElement The function should takes integer values and returns the maximum the number. C. Function name: FindAverage The function should ask the user to input double value for 10 times and it should returns the average Of those values. Function name: backtrackNum The function should take an integer number and print the backtrack of that number. Function name: FindDigitNumber The function should take an integer number and returns the total digit of that number. d. e.

Answer 1

Question a:

Here is code:

int FindMinElement(int num1, int num2, int num3)

{

return (num1 < num2 && num1 < num3) ? num1 : (num2 < num3) ? num2 : num3;

}

Sample code to test:

#include <iostream>

using namespace std;

int FindMinElement(int num1, int num2, int num3)

{

return (num1 < num2 && num1 < num3) ? num1 : (num2 < num3) ? num2 : num3;

}

int main()

{

int num1, num2, num3;

cout << "Enter number #1 : ";

cin >> num1;

cout << "Enter number #2 : ";

cin >> num2;

cout << "Enter number #3 : ";

cin >> num3;

int result = FindMinElement(num1, num2, num3);

cout << "The largest number is : " << result << endl;

return 0;

}

Output:

Question b:

Here is code:

int FindMaxElement(int num1, int num2, int num3)

{

return (num1 > num2 && num1 > num3) ? num1 : (num2 > num3) ? num2 : num3;

}

Sample code to test:

#include <iostream>

using namespace std;

int FindMaxElement(int num1, int num2, int num3)

{

return (num1 > num2 && num1 > num3) ? num1 : (num2 > num3) ? num2 : num3;

}

int main()

{

int num1, num2, num3;

cout << "Enter number #1 : ";

cin >> num1;

cout << "Enter number #2 : ";

cin >> num2;

cout << "Enter number #3 : ";

cin >> num3;

int result = FindMaxElement(num1, num2, num3);

cout << "The largest number is : " << result << endl;

return 0;

}

Output:

Question c:

Here is code:

double FindAverage()

{

double num, sum = 0;

for (int i = 0; i < 10; i++)

{

cout << "Enter number : ";

cin >> num;

sum += num;

}

return sum / 10;

}

Sample code to test:

#include <iostream>

using namespace std;

double FindAverage()

{

double num, sum = 0;

for (int i = 0; i < 10; i++)

{

cout << "Enter number : ";

cin >> num;

sum += num;

}

return sum / 10;

}

int main()

{

double avg = FindAverage();

cout << "\nAverage of numbers : " << avg;

}

Output:

Question d:

Here is code:

void backtrackNum()

{

int num;

cout << "Enter number : ";

cin >> num;

while (num != 0)

{

cout << num % 10 << " ";

num = num / 10;

}

}

Sample code to test:

#include <iostream>

using namespace std;

void backtrackNum()

{

int num;

cout << "Enter number : ";

cin >> num;

while (num != 0)

{

cout << num % 10 << " ";

num = num / 10;

}

}

int main()

{

backtrackNum();

}

Output:

Question e:

Here is code:

int FindDigitNumber()

{

int num, sum = 0;

cout << "Enter number : ";

cin >> num;

while (num != 0)

{

sum += num % 10;

num = num / 10;

}

return sum;

}

Sample code to tesT:

#include <iostream>

using namespace std;

int FindDigitNumber()

{

int num, sum = 0;

cout << "Enter number : ";

cin >> num;

while (num != 0)

{

sum += num % 10;

num = num / 10;

}

return sum;

}

int main()

{

int sum = FindDigitNumber();

cout << "The sum is : " << sum << endl;

}

Output:
