C Sharp (C#) - Classes and Objects

Apublic void Deposit(decimal value) { if (value >= 0) amount = value; }

Bpublic void Deposit(decimal value) { amount += value; }

Cpublic void Deposit(decimal value) { if (value > 0) amount += value; }

Dpublic void Deposit(decimal value) { if (value < 0) amount += value; }

Step-by-Step Solution

Solution:

Step 1: Understand deposit logic
Only positive values should increase 'amount'.
Step 2: Evaluate each option
public void Deposit(decimal value) { if (value > 0) amount += value; } adds value only if positive. public void Deposit(decimal value) { amount += value; } adds all values, including negatives. public void Deposit(decimal value) { if (value >= 0) amount = value; } replaces amount if value is zero or positive, which is incorrect. public void Deposit(decimal value) { if (value < 0) amount += value; } adds only negative values, which is wrong.
Final Answer:
public void Deposit(decimal value) { if (value > 0) amount += value; } -> Option C
Quick Check:
Deposit only positive amounts [OK]

Quick Trick: Add only if value > 0 [OK]
