STEPS IN PRODUCING THIS GPA & CGPA CALCULATOR…..
STEPS IN PRODUCING THIS
GPA & CGPA CALCULATOR…..
Firstly,
declare all the variables that are needed in making on the mini project.
After that, we using
function and in the function we use looping (for) and “if “. For the number of
a timer, uses “if”.
For
the marks, grade points and grades, put the switch (if, else if and else). For example, if we enter marks 80, this
software will automatically choose the grades that is between >=70
&&<=74. Then have set each mark has its own grade point and
grade such as:
Return is referring to chapter function to
return the value we call.
Next step, use “system
("cls")” as the command of
“conio”and “windows” to close the tab and open a new tab
and to stop for a few to next program. For the example is:
For
the second last, inserted the given formula on how too much user can put the
bill of students. Then, put the formula at the end of the switch and use for.
The example is shown below:
For the last, inserted the given formula on how to calculate the GPA. Then, put the formula at the end of the switch and use for & while. The example is shown below:
