// Coding Exercise #1
// Using a for loop and an if statement print out all the numbers
// between 1 and 50 that divisible by 7.

//package main
//
//import "fmt"
//
//func main() {
//	for i := 0; i < 51; i++ {
//		if i%7 == 0 {
//			fmt.Printf("%d ", i)
//		}
//
//	}
//	fmt.Println(" ")
//}

// Coding Exercise #2
// Change the code from the previous exercise and use the continue statement
// to print out all the numbers divisible by 7 between 1 and 50.

//package main
//
//import "fmt"
//
//func main() {
//	for i := 0; i < 51; i++ {
//		if i%7 != 0 {
//			continue
//		}
//		fmt.Printf("%d ", i)
//	}
//	fmt.Println("")
//}

// Coding Exercise #3
// Change the code from the previous exercise and use the break statement
// to print out only the first 3 numbers divisible by 7 between 1 and 50.

// package main
//
//import "fmt"
//
//func main() {
//	count := 0
//	for i := 0; i < 51; i++ {
//		if i%7 != 0 {
//			continue
//		}
//		fmt.Printf("%d ", i)
//		count++
//
//		if count == 3 {
//			break
//		}
//	}
//	fmt.Println("")
//}

// Coding Exercise #4
// Using a for loop, an if statement and the logical and operator
// print out all the numbers between 1 and 500 that divisible both by 7 and 5.

// package main
//
//import "fmt"
//
//func main() {
//	for i := 0; i <= 500; i++ {
//		if i%7 == 0 && i%5 == 0 {
//			fmt.Printf("%d ", i)
//		}
//	}
//	fmt.Println("")
//}

// Coding Exercise #5
// Using a for loop print out all the years from your birthday to the current year.
// Use a variant of for loop where the post statement is moved inside the for block of code.

//package main
//
//import "fmt"
//
//func main() {
//	for i := 1978; i <= 2023; i++ {
//		fmt.Printf("%d ", i)
//	}
//	fmt.Println("")
//}

// Coding Exercise #6
// Consider the following Go program: https://play.golang.org/p/Wo5fIlurnX6
