The various parameters considered in the survey were, the economic status (upper, middle, and lower class) the languages readers prefer (English, Hindi, Regional language) and category of paper (daily, supplement, tabloid). Write a program, which reads data of 10 respondents through the keyboard, and stores the information in an array of integers. The bit-wise information to be stored in an integer is given below:

1  Middle class
2  Lower class
3  English
4  Hindi
