Three positive integer numbers a, band c, such that a<b<c form a Pythagorean triplet if c2= a2 +b2 , i. e,, a, b and c form the sides of a right-angled triangle. To select the values of a and b such that a < b and a, b < max, we can use nested for loops as shown below:

1. if income is less thn, 1,50,000 then no tax
2. if taxable income is in the range 1,50,001-300,000 then charge 10% tax
3. if taxable income is in the range 3,00,001-500,000 then charge 20% tax
4. if taxable income is above 5,00,001 then charge 30% tax.

Let us use variables dd,mm and yy (all of type int)to represent the day, month and year in a given date. The given date is valid only if year (yy)is non-zero, month (mm)is in the range 1 to 12 and day of month (dd) is in the range 1 to mdays, the number of days in a given month mm. An algorithm to determine the validity of a given date is given below.

As the name indicates, the prime factors of a given number are its factors that are also prime numbers, e.g., prime factors of 30 are 2, 3 and 5 but not 1, 6, 10, 15 and 30. One or more prime factors of a given number may repeat, e. g., prime factors of 120 are 2, 2, 2, 3 and 5.
