 Tutorial: Do while loop
Unlike for and while loops, which test the loop condition at the top of the loop, the do...while loop in C programming checks its condition at the bottom of the loop.
A do...while loop is similar to a while loop, except the fact that it is guaranteed to execute at least one time.
 ------------------------------------------------------------------------------------
 The general syntax for do-while-loops in C is: 
 do {
   statement(s);
} while( condition );

// Example
#include <stdio.h>
int main()
{  // this is where the program start execution
    // local variable declaration
    int number = 2;
    // do loop execution
    do
    {
        printf("The number is: %d\n", number);
        // increment in every step
        number = number + 1;
        // while loop execution
    } while (number < 5);
    return 0;
}

 Challenges:
 Using a do while loop:
 1. Print all the numbers from 1 to 10.
 2. Print all even numbers up to 5.
