Question
f. A laborant in a laboratory does a number of antigen tests in one day. Write a program that simulates the number of antigen tests done in a day in a laboratory, displays the number of positives and negatives, and calculates the % of positives in one day. Your program needs to first generate a random number that will show the number of tests done in a day. One laboratory in a day cannot do more than 100 tests and less than 1 (they do at least one). Then for each of the tests, your program needs to generate a random number to show whether they are positive or negative. In order to write this program, you need to have the following three functions used by the main function: test result (void): This function generates a test result. It should randomly return either one or zero. 1 means positive test result and 0 means negative test result. float positive percentage (int,int) : This function takes the total number of positives and the total number of tests and returns the % of positives. For example, if the number of tests done in one day is 50 and the number of positives is 25 then it should return 50.0. int void display results (int, positives, number of negatives and the percentage and prints the results on the screen. int, float): This function takes the number of Sample Run: Today you completed 50 tests and the results are as follows: Test 1: p Test 2: n Test 3: p ..... Test 50: p Number of positives: 25 Number of negatives: 25 % of positives: 50.0%
