Can you write this :

Question

hello

is it possible to write something like:

for (I=0,i<n,i++,j=0,j<n,j++){
xxxx
}

it don't Work, also

if I want the same I can do :

for (I=0,i<n,i++) {
j=I;

xxxx
}

but if I want something like

for (I=0,i<n,i++,j=2,j<n-1,j++)

how can I do like this?

thank you for your help and time

Answer 1

for(ins,ins,...,ins;con,con,...,con;step,step,...,step)

ins → instruction
con → condition
step → increasment ,decreasment ...

notice that between 2 instructions the comma is used (,) and between an instruction and a condition (;) is used
same thing for (con,con) and (con;step)

you can also write

for(ins;;step) no condition
for(ins;con;) no step
for(;con;step) no ins
for(;;;) infinit loop

Answer 2

Yes, you can you have to write like this
#include <iostream>
using namespace std;

int main() {
int i,j;
for(i=0,j=2;i<6,j<4;i++,j++)
{
cout << "Hello\n";
}
return 0;
}
