I have a loop and inside my loop are things that will do some long task. I want to figure which task is taking my time the longest. how can i do this

example

for (int i = 0; i < numberOfthinsTobeProcessed; ++i)
{
getData(i); // long task
decodeRawdata() //long task
updateDatabase()//longtask
updataPlot() //anotherlong task
}
showTimeconsumedHere() <-- I want to show the variuos time consumed of my long tasks
