Write a program that removes all non-alphabetic characters from the given input. Ex: If the input is: -Hello, 1 world$! the output is: Helloworld Your program must define and call the following function that takes a string as a parameter and returns the string without any non- alphabetic characters. string RemoveNonAlpha (string userString) Remove all non-alphabetic characters - functions 1 #include 2 #include 3 using namespace std; 4 5 string RemoveNonAlpha(string userstring) { 6 string final str; 7 for (int i = 0; i < userstring.size(); ++i) 8 { 9 if ((userstring[i] >= 'a' && userstring[i] <= '2') || (userstring[i] >= 'A' && userstring[i] <= 'Z')) 10 final_str += userstring[i]; 11} 12 return final_str; 13} 14 int main() { 15 string user_input_string; 16 cout<<"Enter the string: "<

Please use C++ and only use header<iostream>. Any others will not be accepted. Hint included from for assignment. Thank you!

Write a C code. You should use scanf() and use printf to show the values that you have assigned. The structure type must have following information:Name of structure: city_pComponents of structure:Name (name of the city)Population (number of people in the city)In_California (is the city inside California or not)Speed_limit (usual speed limit inside the city)

Without using any string literal notation, how do you create the C++ statement that manually creates a null-terminated C-style string as an array of characters. Use the string “Sampson” as your example. Which element is stored in the base address of the array?
