Hi
I have been working with while and for loops, and I want to know how to transpose or change a while loop to a for loop and vise versa
I need your help with this.
Thank you

What have you tried so far? What problems are you having with this homework assignment?

This is what I have done sir.
%while loop
x=0
while x<20
disp(x);
x = x+2;
end
%%for loop
x = 0
for x=0;x<20;x=x+2
disp(x)
end

In MATLAB, fo create a for loop, instead of specifying x=x+2 like you do in C, you write the skip as 0:2:20. This would make your code look like:
x=0;
for x=0:2:20
disp(x);
end
For creating while loop, it is similar to what you mentioned, as we have in C:
x=0;
while x<=20
disp(x);
x=x+2;
end
The equality sign is required in while as the condition is evaluated at start and logic will fail to enter the loop when you have updated the value of x to 20, but are yet to print it.

The for loop for your while loop would be
% 0:2:20 will produce a matrix starting at 0, with increment step of 2 in each iteration and will go till 20
for x=0:2:20
disp(x);
end
