Question

when using c++ language .how to loop 3 things with differents function header

Answer 1

to loop 3 times as you want you can you a for loop

written like this . for(int counter=1; counter<=3 ; counter++}
{ statements comes here
}

Answer 2

you need to put a conditional if to decide which function structure to use..

for (int counter=0;counter<3; counter++)
{
if(counter==0)
function(counter,var1);
else if(counter==1)
function(counter,var1,var2);
else
function(var1);
}

maybe :)
