Question

i wrote a code can you change this code so i can set the input and output file name i need to set the name of input file and output file but i dont know how to.. please help me ---------------------------------------------------------------------------------------------------------- example cout << "Please enter the name of the input file a:"; //Enter name of input file cin.getline(filename, SIZE); //Read input file inFile.open(filename); //Open input file cout << "Please enter the name of the output file a:"; //Enter name of output file cin.getline(filename,SIZE); //Read output file outFile.open(filename); //Open output file ---------------------------------------------------------------------------------------------------------- code that i wrote ------------------------------------------------------------------------------------------------------------------- #include #include #include #include #include using namespace std;

Explanation / Answer

you want to set the input and output file name but your code not even near to that.... well your code is not properly intended so it was very reading it but then also i tried, all that i understood from your code is that its for the calculation of rainfall and sales of each month and to sort that..but not to set the input and output file name. here i am giving you a detailed example to set the input and output file name..try to follow it and enjoy :) Text file streams are those where we do not include the ios::binary flag in their opening mode. These files are designed to store text and thus all values that we input or output from/to them can suffer some formatting transformations, which do not necessarily correspond to their literal binary value. Data output operations on text files are performed in the same way we operated with cout: // writing on a text file #include #include using namespace std; int main () { ofstream myfile ("example.txt"); if (myfile.is_open()) { myfile
