use c++ to Write a program to initialize a string (large string e.g. 500 characters), compute the frequency of each English letter and draw the bar chart of it. Ignore any special or numeric characters.

Please help me solve this problem C. Chess Boundary Positions: Write a program called chess_pos.py On a chessboard, positions are marked with letters between a and h for the column and a number between 1 and 8 for the row. Give a 2 character input string with a letter (a-h) and a number (1-8), print "Corner" if the value indicates a square on a corner. Print "Border" if the value indicates a square on an edge of the board. Otherwise, print "Inside".
