1 2 4 8 。。。512 1024 Program this question

program jiafa;

vari,a,b:integer;

begini:=1;

repeat

write(i,'+');

a:=a+i;

i:=i*2;

until i=1024;

a:=a+i;

write('1024');

write('=',a);

readln

end.The above ones seem to be in C, and this is the original program written in the real Pascal language.

Dude, to start with 1, I'm going to use for simpler.

vari,s,k:integer;

begins:=1; k:=1;S is set to 1 because it is added from the beginning, and K is set because it is multiplied by 2

for i:=1 to 10 do because 1024 is 2 10, so to ten times.

begink:=k*2;How to calculate the power of the square.

s:=s+k;Accumulate.

end;writeln(s);

end.This is better than repeat

Until it's much simpler, with less time, less memory, easy to understand, and easy to write.

int x;

for(int i=1;i<=10;i++)x += ,i)

The value of the last x is what is sought.

int i = 1;

int result=0;

doresult += i;

i = i * 2;

while (result < 1024);

I don't know what program you're using.,Anyway, it's more common to write it like this.,Finally, you can pull the result output.。

The details are as follows:Using the formula: sn=a1(1-q n) (1-q) =(a1-an q) (1-q) (q≠1) So:

Additive calculations:Combining two or more numbers and quantities into one number or quantity. The symbol for addition is the plus sign "+", and when adding, the items are connected with a plus sign.

Addition has several important properties. It is commutative, which means that the order is not important, and it is again interrelated, which means that when more than two numbers are added, the order in which the addition is performed does not matter. Repeat plus 1 is the same as counting; Adding 0 does not change the result.

Addition also follows the relevant actions.

This is the sum of proportional sequences. The formula is sn=a1(1-q n) (1-q) =(a1-an q) (1-q) (q≠1) and the solution is sn=(1-1024 2) (1-2)=2047
