Answer to Question #132725 in C++ for phile

Question

Write a program that uses for loops to perform the following steps:
a. Prompt the user to input two integers: firstNum and secondNum
(firstNum must be less than secondNum).
b. Output all odd numbers between firstNum and secondNum.
c. Output the sum of all even numbers between firstNum and secondNum.
d. Output the numbers and their squares between 1 and 10.
e. Output the sum of the square of the odd numbers between firstNum and secondNum.
f. Output all uppercase letters

Answer 1

int firstNum, secondNum, count=0, sum=0;
	cout << "a) Input two integers: firstNum and secondNum (firstNum must be less than secondNum)" << endl;
	cin >> firstNum >> secondNum;
	cout << endl;
	cout << "b) ";
	for (int i = firstNum; i <= secondNum; ++i)
		if (i % 2 == 1)
			cout << i << " ";
	cout << endl;
	for (int i = firstNum; i <= secondNum; ++i)
		if (i % 2 == 0)
			count += i;
	cout << "c) Sum of all even numbers = " << count<<endl;
	cout << "d) ";
	for (int i = 1; i <= 10; ++i)
		cout << "Number = " << i << " and square = " << i * i << endl;
	for (int i = firstNum; i <= secondNum; ++i)
		if (i % 2 == 1)
			sum += i * i;
	cout << "e) Sum of the square of the odd numbers: " << sum << endl;
	cout << "f) ";
	for (int i = 0; i < 26; ++i)
		cout << char(i + 65) << "  ";
