- Let s1 be " Welcome " and s2 be " welcome ". Write the code for the following statements: (a) Check whether s1 is equal to s2 and assign the result to a Boolean variable isEqual.arrow_forwardSingular to Plural. Create a program that accepts a word in singular, and produces the corresponding plural. Use the following rules: a. If the word end in ‑s, -ss, -sh, -ch, -x, or –z, then add –es to the word. For example, the plural of tax is taxes b. If the word ends in -fe, then replace the ending with –ves. For example, the plural of wolf is wolves c. If the word ends in y and the previous letter is a vowel, then add –s to the word. For example, the plural of boy is boys d. If the word ends in y and the previous letter is a consonant, then change the –y ending with –ies. For example, the plural of city is cities e. If the word does not meet the criteria above, then add –s to it.arrow_forwardcircles) Write a program that prompts the user to enter the center coordinates and radii of two circles and determines whether the second circle is inside the first or overlaps with the first, as shown in Figure 4.11. (Hint: circle2 is inside circle1 if the distance between the two centers <= | r1 - r2| and circle2 overlaps circle1 if the distance between the two centers <= r1 + r2.arrow_forward
- 10) Write a program that translates a letter grade into a number grade. Letter grades are A, B, C, D, and F, possibly followed by + or -. Their numeric values are 4, 3, 2, 1, and 0. There is no F+ or F-. The symbol + increases the numeric value by 0.3, and the symbol - decreases it by 0.3. For example: Enter a letter grade: B- The numeric value of B- is 2.7.arrow_forwardWhich of the following statements is true about the difference between while looping and do..while looping? a) while loops require brackets to be syntactically correct b) only do while loops require a condition c) while loops must mutate a variable in order to break d) do while loops ensure that the body executes at least oncearrow_forward12: guess.cpp) Write a program that plays a guessing game with the user. The user should pick a letter, and the computer should try to guess the letter. After each guess, the user should tell the computer whether its guess was too high or too low. With this information, the computer should be able to guess the letter within five tries. The user should be able to give whole words or single upper or lower case letters as responses.arrow_forward
- 1. Write program to check whether a number is Palindrome or not. [Hint]: A palindrome number is a number such that if we reverse it, it will not change.

For valid arguments, prove that the argument is valid using a truth table. For invalid arguments, give truth values for the variables showing that the argument is not valid.arrow_forwardState whether the following are true or false.
