Mathias Meyers · Answer 1

int i = 0; while (i < 4) { readData (); i = i + 1; }

Step-by-step explanation:

the above method is proper way to call the method readData four times because it will start from zero and will call readData until i=3, if i=4 it will stop calling readData.

double k = 0.0; while (k! = 4) { readData (); k = k + 1; }

This is not the proper way to call readData four times because it will call readData only if k!=4 otherwise condition k!=4 will not be true and readData will not be called.

int i = 0; while (i < = 4) { readData (); i = i + 1; }

This is not the proper way to call readData four times because condition i<=4 will call readData five times starting from zero to 4.

int i = 0; while (i < 4) { readData (); }

This is not the proper way to call readData four times because it will call readData only one time i. e. value of is not incremented.
