Let us use variables m and n to represent two integer numbers and variable r to represent the remainder of their division, i. e., r = m % n. Euclid's algorithm to determine the GCD of two numbers m and n is given below and its action is illustrated form= 50 and n = 35.

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.

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.

switch statement is generally best to use when you have more than two conditional expressions based on

a single variable of numeric type. For instance, rather than the code

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.

No, but it is not a bad idea to put default statements in switch statements for error- or logic-checking

purposes. For instance, the following switch statement is perfectly normal:
