Do loop example

Answer 1

When someone says something like "I got stuck in this do loop with my insurance company" they're saying that they're getting the runaround -- any frustrating never-ending situation. The origin of the phrase "do loop" is from computer programming. There are ways to write a program that repeats a set of instructions until some goal is accomplished. Because these are written as as some variation on "DO { some actions } UNTIL { goal is met }" they are called "Do loops". A common programming hazard is to construct such a loop without proper logic for deciding when "goal is met", so that the loop never ends.

Answer 2

A nested loop is simply a loop within a loop. An example of such a loop is where you wish to traverse a two-dimensional array. The simplest way to traverse such a structure is to use a loop to traverse each row and a nested loop to traverse the elements within each row.

int a[4][5]; // a 4x5 array of integers (4 rows, 5 columns).

// ...

for (row=0; row<4; ++row) // traverse rows

{

for (col=0; col<5; ++col) // traverse columns

{

std::cout << a[row][column] << ", "; // print value at current row and column

}

std::cout << endl; // keep each row on a separate line

}
