- 9. Write a program that reads from the user a sentence. The program should count the number of occurrences of the character 'a' in the sentence. 10. Write a program that reads from the user 10 words. The program then should count and print the number of words that start with character 'a'.4. Write down a regular expression for floating point numbers in Scientific notation. First write a regular expression for signed numbers and number with decimal point and then use these regular expressions to write the regular expression for scientific notation. Language Example Pattern All sequences of digits starting with + or - +6, -12 Signed Includes a decimal point and at least one digit to the left and right of the point. Signed or Decimal followed by e or E and a Signed number 10.541, 45.02 Decimal -10e-01, - 43E+10 ScientificSingular 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.
- a) Give an example of a string that is neither in the language of R nor in S. b) Give an example of a string that is in the language of S but not R. c) Give an example of a string that is in the language of R but not S. d) Give an example of a string that is in the language of R and S. e) Design a regular expression that accepts the language of all binary strings with no occurrences of 010.quadratic.py by using "sys.argv" ● Create a program, quadratic.py, that takes in three arguments that represent the a, b, and c values in the quadratic formula. The values should be to two decimal places. You do not need to account for imaginary values. Then print out both roots in the form: “The solutions are x and y” Where x and y correspond to the positive and negative roots, respectively.Exercise 7. Let E={a,b,c}. Write a regular expression which can generate the language that has odd number of a's, even number of b's and a single c character. %3D
- Create a four-function calculator for fractions by using following formulas. a) Addition: a/b + c/d = (a*d + b*c) / (b*d) b) Subtraction: a/b - c/d = (a*d - b*c) / (b*d) Note:The program should display above mentioned formulas first. The user should take the values of a, b, c, d from user. The program should then display the result of each process Addition, Subtraction, Multiplication, and Division on separate lines on screen.2. Write a code snippet that can arrange the alphabets of a name entered by user in alternate cases. Note: Ignore white spaces. Input String : Timothy Olyphant Output String : TiMoThY oLyPhAnT Input String : Olga Kurylenko Output String : OlGa KuRyLeNkO Use programming language C.Write the following function to check whether a string is a palindrome assuming letters are case-insensitive: bool isPalindrome(const string& s) Write a test program that reads a string and displays whether it is a palindrome.
- French Articles: French country names are feminine when they end with the letter e, masculine otherwise, except for the following which are masculine even though they end with e: le Belize le Cambodge le Mexique le Mozambique le Zaïre le Zimbabwe Write a program that reads the French name of a country and adds the article: le for masculine or la for feminine, such as le Canada or la Belgique. However, if the country name starts with a vowel, use l’; for example, l’Afghanistan. For the following plural country names, use les: les Etats-Unis les Pays-BasCan you describe situations in which it might be necessary to trim leading or trailing characters from string data input by the user? Can you describe situations in which it might be necessary to pad string data or to replace portions within a string?i want code in c language Research our planet population growing issues online. Get approximations for the current population and its growing rate (the percentage by which it’s likely to increase this year). Write a program that calculates a) World population growtheach year for the next 25 years, using the supposition that the current growth rate will remain unchanged. b) Print the results in a table. The first column should display the year from year 1 to yearThe second column should display the anticipated world population at the end of that year.The third column should display the numerical increase in the world population that would occurthat year.
