Hi, I need to write a C++ program to do the following things, and i have displayed my attempted code. Please let me know if there is more effective way to do this. - I need to calculate the % based on the input values (run-time) - The percentage value will keep on increasing based on the input values. For eg If the input is 30, then it after completing the 1st operation it should display 1 % .... and after completing 2nd operation it should display 2 % and so on, and when it completes 30th operation it will display 100 %. Note: the input values is a random number. My logic Case 1: If the input is 30 1/30 = 0.03 and multiply the result by 100 then the value is 3 % ......... 30/30 = 1 result will be 100 % It is ok to have the % is some increasing order, rather than more presisely with 1%,2% etc. But problem is my logic will not work for this case Case 2: If the input is for eg 300 then 1/300 = 0.033 and multiply the result by 100 then the value is 0.33, in this case i should multiply by 1000 instead of 100 to get the round value. Any idea on how to deal with this. Thanks in advance.

Where? I also don't understand the problem here: Why do you think you need to multiply the result by 1000? Why do you think that .033 * 100 = .33? Did you try that on a calculator? If you multiply by 1000 instead of 100, you won't get 1% for 1/300, and the progress bar will finish (a) at 1000%, or (b) when you're 1/10th of the way through the task.
