Write a program that lets the user enter a string and displays the character that appears most frequently in the string. Suggest using count, alphabet_string = 'abcd….z', upper(),

C PROGRAM

Every data structure that we use in computer science has its weaknesses and strengthsHaving a full understanding of each will help make us better programmers!For this experiment, let's work with STL vectors and STL dequesFull requirements descriptions are found in the source code file Part 1Work with inserting elements at the front of a vector and a deque (30%) Part 2Work with inserting elements at the back of a vector and a deque (30%) Part 3Work with inserting elements in the middle, and removing elements from, a vector and a deque (40%) Please make sure to put your code specifically where it is asked for, and no where elseDo not modify any of the code you already see in the template file This C++ source code file is required to complete this problem

Strings and string manipulation Part A: Building upon an Existing Solution  Redesign the solution in the following manner. Ask the user for their name and their email addresses before you display the results of the conversions. When the user enters their email address search the string for the @ symbol. If the symbol is not found, ask the user to re-enter their email address till they get it right. When you display the conversion output to the user, you must include the user’s name in the output. Part B: Write Something New! Write a complete and syntactically correct Python program to solve the following problem: Input a date in numeric format from the user e.g. mm/dd/yy. Examine the month entered by the user, if it is larger than 12 or smaller than 1, issue an error message and ask for input again. Perform similar validation tests for the date and year. Year must be 2015. (Any other year is invalid).  In addition, the year must only be two digits long.. Once all input has been…
