How to measure execution time of command in windows command line?
is there a program which counts how fast .exe file is fulfilled? For example, if I must write c++ that takes one number from input file, multiply it with 2 and outputs in output file. And if I start c++ program, I can't tell how fast it is completed, cause for me it seems like 0.1 sec - blinking window. So is there any chance telling exactly time of it?
