Q1: Output a welcome message to the console. The message should be contained inside of a string variable that is accessible by the entire program via it's scope. Q2: Create a conditional statement that outputs the grade of a student based on their mark. You may use an IF or a SWITCH. I'll get you started. var grade; var mark = 94; // ... console.log("The student received an " + grade + " in the course!"); Q3: This the following 4 lines of code has a bug and doesn't add correctly. Find the bug and fix it so the output is correct. Add comments to show that you've corrected the bug appropriately. var y = "4"; var x = 20; var total = x + y; console.log(x + " + " + y + " = " + total);
Control structures
Control structures are block of statements that analyze the value of variables and determine the flow of execution based on those values. When a program is running, the CPU executes the code line by line. After sometime, the program reaches the point where it has to make a decision on whether it has to go to another part of the code or repeat execution of certain part of the code. These results affect the flow of the program's code and these are called control structures.
Switch Statement
The switch statement is a key feature that is used by the programmers a lot in the world of programming and coding, as well as in information technology in general. The switch statement is a selection control mechanism that allows the variable value to change the order of the individual statements in the software execution via search.
