	}
}

Program 2:

			if num == 3 {
				break
			}
			fmt.Println("Hello World")
		}
	}
}

 

Program 3:

package main

			fmt.Print(cnt*num, " ")
		}
		fmt.Println()
		if cnt == 4 {
			break
		}
	}

Answer Program 1:

Output:

Hello World
Hello World
Hello World
Hello World
Hello World

Explanation:

In the above program, we created a loop to execute 10 times based on the value of the num variable. But it will print the "Hello World" message only 5 times. Because we used the break statement to exit from the loop when the value of num becomes 6.

 

Answer Program 2:

Output:

Hello World
Hello World
Hello World
Hello World
Hello World
Hello World

Explanation:

The above program will print the "Hello World" message 6 times on the console screen. As we know that, the break statement will break only the immediate loop. Here, break statement only breaks the inner loop.

 

Answer Program 3:

Output:

2 4 6 8 10 12 14 16 18 20 
3 6 9 12 15 18 21 24 27 30 
4 8 12 16 20 24 28 32 36 40

Explanation:

In the above program, we printed tables from 2 to 4 on the console screen. Here, outer loop will be terminated when the value of the cnt variable becomes 4, That's why it will print the table till 4 instead of 5.

 

Answer Program 4:

Output:

./prog.go:6:6: undefined: num
./prog.go:7:6: undefined: num
./prog.go:10:13: undefined: num

Explanation:

The above program will generate syntax errors because here we did not declare the num variable.

 

Answer Program 5:

Output:

1 2 3 4 5 7 8 9 10

Explanation:

 

The above program will print the numbers from 1 to 10 except 6 because we used the continue statement. The continue statement is a skipping statement, it will skip the execution loop body below the continue statement.
