Write an intelligent C++ program to process the commands like these.

add up numbers 10 56 12 also 89 and output the total give me the average of 80 and all these 85 90 92 56 what is the max of 56 12 98 56 23 12 98 find the min among 34 98 24 76 100 11.1 22.2 33.3 44.4 total these numbers tell me the purpose of life ok that is enough bye 

OK, let us simplify the requirements :-) Write a program to read the input lines and process them. End the program when current line has a word "bye". After reading each line, find the total, average, min and max of all the numbers in the line. Also, look for the following key words: total, average, min & max. You can ignore all other words. So, here is the output for the sample input given above.

10 56 12 89 total 167 80 85 90 92 56 average 80.6 56 12 98 56 23 12 98 max 98 34 98 24 76 100 min 24 11.1 22.2 33.3 44.4 total 111 tell me the purpose of life - I am not yet that smart to answer this one! OK bye! 

Here is the pseudocode/code for the core logic.

//read a line while (getline(cin, line)) { istringstream lineInput(line); string word; //get one word at a time! while (lineInput >> word) { double value; //is the word number or string? if (istringstream(word) >> value) //number! else //string! }
