Question Discussion & Solution

According to given conditions,

Clearly, the man is now facing West.

Hence, ‘West’ is the correct answer.

Let’s check each option,

Thus, the sequence is wxwzwy wxwzwy wxwzwy.

The correct answer is All of the Above.

 Key Points

• Decision making structures require that the programmer specifies one or more conditions to be evaluated or tested by the program.
• It also involves a statement or statements to be executed if the condition is determined to be true, and optionally, other statements to be executed if the condition is determined to be false.
• C programming language provides the following types of decision-making statements.
• if...else statement
  • An if statement can be followed by an optional else statement, which executes when the Boolean expression is false.
• switch statement
  • A switch statement allows a variable to be tested for equality against a list of values.
• C goto
  • The goto statement in C/C++ also referred to as the unconditional jump statement can be used to jump from one point to another within a function.

 Additional Information

• C break:
  • This loop control statement is used to terminate the loop.
  • As soon as the break statement is encountered from within a loop, the loop iterations stop there, and control returns from the loop immediately to the first statement after the loop.

Concept:

Resistance: The property of electrical materials and electrical instruments that opposes the flow of current through them is called resistance.

It is denoted by R. The SI unit of resistance is the ohm (Ω).

Power: The rate of work done by an electric current is called power. It is denoted by P. The SI unit of power is the watt (W).

Power dissipation (P) is given by:

\(P=VI=\frac{V^2}{R}=I^2R\)

Where V is the potential difference across resistance, I is current flowing and R is resistance.

Calculation:

With R = 50 Ω, and V = 220 V, the power required by the bulb will be:

\(P=\frac{V^2}{R}=\frac{220\times 220}{50}\)

P = 968 W
