Give an example of a nested if-else statement.
Write a program that inputs a number and a letter and then decides whether the square is a black or white square. Hint: For letters a, c, e, g you may apply a modulus 2 operation on the number to decide the result to be a black or white square. The situation is reversed for the rest of the letters. You may use a switch selection in combination with an if/else selection statement or you may use nested if/else selection statements with logical operators. You may assume the user enters valid values.
Sample outputs:
Enter square value: e 4
White square
Enter square value: g 7
Black square
C++
Write an if-else statement with multiple branches. If givenYear is 2101 or greater, print "Distant future" (without quotes). Else, if givenYear is 2001 or greater (2001-2100), print "21st century". Else, if givenYear is 1901 or greater (1901-2000), print "20th century". Else (1900 or earlier), print "Long ago". End with a newline. Remember to use println instead of print to output a newline.
