Loops Introduction
There may be a situation, when you need to execute a block of code several number of times. In general, statements are executed sequentially: The first statement in a function is executed first, followed by the second, and so on.

Programming languages provide various control structures that allow for more complicated execution paths.

A loop statement allows us to execute a statement or group of statements multiple times.

There are 3 types of Loops in C++
1) While loop
2) Do while loop
3) For loop

-> Nested loops - loop inside loop is called nested loop we will learn it further.


Syntax of While loop
while ( condition )
{
    code
}


Syntax of do While loop
do
{
    code
} while (condition);


Syntax of for loop
for (size_t i = 0; i < count; i++)
{
    code
}
