Exercises

Numbers

• input integers x and y and print their sum, difference, product, quotient and remainder
• input integers x and y and print one of these 3:
  • they are equal
  • x is bigger
  • y is bigger

Strings

• write "Hello world!" to screen
• input name from user and greet him, for example "Hello Bob!"
• input name from user and greet him only if his name is "Bob"

Loops

• print all positive even integers less than 10
• print sum of first 10 positive integers
• input integer n from user, and print "abc1", "abc2".. etc where numbers increase until n
• input integer n from user, it must be an even and positive number
• input integer n and find factorial of that number
• input integers m and n and print all pairs "(0,0)", "(0,1)",.."(1,0)".. etc where first number goes 0..m and second 0..n
• print Fibonacci numbers smaller than 50
• input 5 numbers and print the smallest
• input integer n and print number of digits, e.g. 1111 -> 4
• input integer n and print number with reverse digits, e.g. 123 -> 321 (hint: use mod operator %)

Functions

• make a function square(n: Integer) that returns square of n
• make a function rectArea(w: Integer, h: Integer) that returns area of a rectangle
• make a function bmi(weight: Real, height: Real) that returns BMI of a person following the formula
• make a function printMultiple(n: Integer, s: String) that prints s text n times
• make a function fact(n: Integer) that returns factorial of n (and call it from main to test it)
• make a function fib(n: Integer) that returns Fibonacci of n
