Calculation on text-file ?

Question

Hi

This may be an extension to the above linked post :)

http://www.c-sharpcorner.com/Forums/Thread/237449/counting-characters-digits-text-file.aspx

My questions would be . . what if text-file , we are getting and reading content caries i.e

Scenario 1 : program that will read all the integer numbers and find the smallest, the largest, the sum, and the average values. Sort all numbers read in ascending order and output all results into another file name.

scenario 2 : program that reads the matrix from the text and output the average value of each row and column, smallest and the biggest number of each row/column. Smallest and biggest number of the whole matrix and the average value of the whole matrix to a text file.

Well input to this is : @in text-file

60 57 94 8 95 68 13 30 6 62 42 65 82 52 67

21  95  12  71  1  90  31  38  57  16  90  40  79  35  6  
72  98  95  19  54  23  89  60  5  26  23  6  13  70  38

Cheers Ty for help

OK here's some code for scenario 1: #include #include #include #include #include using namespace std; int main() { vector vec; ifstream inFile; ofstream outFile; string inFilename; string outFilename = results.txt; string number; cout cin >> inFilename; cout inFile.open(inFilename.c_str()); if(inFile.fail()) { cout inFile.close(); return 1; } while(!inFile.eof()) { getline(inFile number ' '); if(number.length() == 0 || number == 
) continue; int i = atoi(number.c_str()); vec.push_back(i); } inFile.close(); int min = vec[0]; int max = vec[0]; int sum = 0; for(int i = 1; i { if (vec[i] if (vec[i] > max) max = vec[i]; sum += vec[i]; } double average = (double)sum/vec.size(); outFile.open(outFilename ofstream::out); outFile outFile outFile outFile sort(vec.begin() vec.end()); // write them to a line on separate lines outFile for(int i = 0; i outFile.close(); return 0; } See if you can figure out how to deal with scenario 2 now.
