I have just start working at my final year project in communication engineering and Iím doing some c++ programming as well. My question is how can I read numbers from a .txt or .xls file and make some calculation with it, then output this calculation in another .xls file.
Lets say the file that I want to read from contains: "4 5"
and i would like to create another .xls file that contains: "4 5 9" (9 is the sum of the two numbers)
please everyone I need your help ASAP
