Answer:
In studies about new medicines, researchers usually give one group of patients the medicine that is designed to treat an illness. They give another group of patients a placebo, which is taken the same way as the medicine but does not actually contain the ingredients of any medicine. Different medicines are tested in different experiments, but the placebos usually contain the same non-medical ingredients. If both groups of patients are healed, then researchers cannot be sure whether the medicine caused improvement, but if the group given the medicine is healed while the group given the placebo remains ill, researchers can conclude that the medicine causes the illness to go away.
In medical experiments, which group receives placebos?
the experimental group
the control group
both the experimental and control groups
neither the experimental nor control group

{{5,10,15,20},{25,30,35,40}} is answer where zero is not found.
<u>Explanation:</u>
This program finds zero in giving as arrays of value as a parameter. The program has two loop. One is a row of the array and the other is column loop for each row o an array. For loop is created with a variable namer row and the loop ends with a length of the array of each row.
In side row for loop col loop is created and loop ends with each row-column length of cells. If data in each cell i.e (row, col) calue is zero it returns true and the loop is terminated immediately.
In case if the value of the cell doesn’t found zero it never terminates the loop and continuous loop and returns a false value. Find Zero functions accept the two-dimensional array and check whether cell value is zero. If it is zero found return true otherwise it returns false.
