Write a C program frequency_analysis.c which reads characters from its input until end of input. It should then print the occurrence frequency for each of the 26 letters 'a'..'z'. The frequency should be printed as a decimal value and an absolute number in exactly the format below. Note upper and lower case letters are counted together.
