You can compile an executable exe file

It's c++ code?

for (i=1... it's error!
for ( int i = 1... it's true
and.. cout << square << endl;

You just take a problem in real life and then you try to recreate all of its functions in your code
eg. a math formula which you find hard to calculate by yourself
or just search the internet
i found : write a function that finds all perfect squares (1*1 or 1 2*2 or 4) in a given range
if I have a problem like this, I am looking for a formula to calculate the answers easy (1-4-9-16) (1+3=4 4+(3+2)5=9 9+(3+2+2)7=16)
so you need a start range and end range input (like 3 - 5)
(i thought in c++ it was cin not sure)
var start = cin();
var end = cin();
(sorry for bad c++ skills)
then define what p is
the easiest way to do that is with a for loop
var p = 3;
for (i=1; i<start; i++){
p+=2;
}
now that we did that, we just have to calculate the square in the range which is also the easiest with a for loop
var start = cin();
var end = cin();
var square = start*start;
print(square);
var p = 3;
for (i=1; i<start; i++){
p+=2;
}
for (i=start; i<end; i++){
square+=p;
print(square);
}
thats how I do that things

sorry, no I'll write it again but im not good at c++
first code piece
int start;
cin >> start;
int p = 3;
for(i=0; i<start; i++)
{
p+=2;
}
the second part
int start;
int end;
cin >> start;
cin >> end;
int square = start*start;
cout << square;
int p = 3;
for (i=1; i<start; i++)
{
p+=2;
}
for (i=0; i<end; i++)
{
square+=p;
cout << square;
p+=2;
}

I guess the language shouldn't matter. but I guess what I'm askingbis-when I find a problem how do I learn to convert it to code. for example: I want to built a small chess game in c++ but I do know where or how to start
