C Programming Tutorial - 26 - do while Loops

Sucks for the student who got 0 on the first test.

How To Zoom IN :
Press the windows key with "+" key then click on the "views" option after that select full screen.
and increase the magnification to 200%.

It demonstrates the Do while loop well, but I wouldn't choose 0 as the quit command since you can score 0

Where do you learn all of the things you teach in your videos? I am impressed by how much stuff you have on your channel and the variety of content from biology to computer programming to 3D animation. It's amazing! How do you do it?

Bucky knows lots of stuff that's for sure. Great vid.

[overblues]

had troubles understanding the condition part, but understood it after watching this, thankyou!

[maruf]

It would be better if it were zoomed in.

Dude I'm So confused About Do while loop..You r good..but u used too much Floats ha ha that's Blow my mind..I think I can understand After watching 3-5 times...Keep it up bro nice tutorials

[briankiprono]

Good execution of the joke made it even funnier

Does 'grade += scoreEntered' equals this code 'grade = grade + scoreEntered' ?

[ajay]

why you are using "grade" in this program. instead use total

[NavjotSingh-bzrn]

Your tutorials are awesome but you should increase the font size from next time

Hi. How about when you need to have an output like this:

OUTPUT
Enter a number: 1
Enter a number: 2
Enter a number: 3
Sum = 6

Is it the same process?

[lolofuk]

I have a question...Why If I put only one test with score enetered 54 and then I put 0 the average is calculated both with 54 and 0 so if I print average after the loop the result is 27?...

[gabemorris]

whats the point of the do part? why not just start off with the while (scoreEntered != 0) and get rid of the do part all together?

How do i retun back to my main function after the while condition becomes false. Once my while statement becomes false my programs ends and i need it to continue

[shadowmeth]

It's not a bad programming practice if we leave the false condition code area empty in the shorthand if statement right?
#include <stdio.h>
#include <stdlib.h>

int main()
{
float grade = 0;
float scoreEntered = 0;
float numberOfTests = 0;
float average = 0;
printf("Press 0 when complete. \n\n");

while(true){
\n", numberOfTests, average);
printf("\nEnter test score: ");
scanf(" %f", &scoreEntered);
(scoreEntered == 0) ? break : ;
grade += scoreEntered;
numberOfTests++;
average = grade / numberOfTests;
}


return 0;
}

A great tutorial! A question:
scanf() line: instead of scanf(" %f", "ScoreEntered"); I wrote scanf( " %.2f", "ScoreEntered"). The program only run once. What makes difference between %f and %.2f here?

Thanks

Is there a way to clear the screen? (like "cls" in batch) And is it possible to change the color of the letters? (like "color .. " in batch)

[MultiAkram]

guys, i typed in the 16th line scanf("%.0f", &scoreentered); and thanks to that my program kinda wasn't working ( please try this )
can i know why?
