For loops in C++ consist of three parts, all of which are optional. Each part is separated by a semi-colon, which is not optional, and each part may include multiple statements, separated by commas.
The first portion is the initial expression, which can be used to both declare and initialise variables used within the loop. If variables are declared, they are local to the loop and fall from scope when the loop ends.
The second portion is the conditional expression that is executed at the end of each iteration of the loop. If the expression evaluates false, the loop terminates. This is typically used to evaluate the variables initialised by the initial expression.
The final portion is the end loop expression, which is executed at the end of each iteration prior to the conditional expression being evaluated. This is typically used to increment or decrement variables initialised in the initial expression.
Within the body of a loop, jump statements can be used to exit the loop regardless of the conditional expression, or start a new iteration before executing any remaining commands within the loop. Jump statements include break, continue, goto and return, and are typically used in conjunction with a conditional expression.
An infinite for loop has the following from:
for(;;)
{
// The body of the loop must evaluate a conditional expression to allow
// the loop to terminate via a jump statement.
}
A for loop that repeats 10 times can be expressed as:
for(int x=0; x<10; ++x)
{
// Variable x will fall from scope when the loop ends.
}
The loop can also be expressed as an infinite loop:
int x=0;
for(;;)
{
if( ++x == 10 ) break;
}
// x is still in scope at this point, and has the value 10.
Most for loops can also be written using while() loops, however variables used by the conditional expression must be declared outwith the loop, and will remain in scope when the loop terminates.
int x=0;
while(x++<10)
{
// First time around, x will be 1.
}
// x is still in scope at this point, and will have the value 11.

How does C plus plus endeavor to represent the loop paradigm?
Iterative loops in C/C++ are represented by for(), while() and do...while() code blocks. Recursive loops are represented by functions calling themselves.
