Problem Statement
Use compound assignment operators (+=, -=, *=, /=, %=).
Real Life: Like updating your bank balance, score etc.
Real Life: Like updating your bank balance, score etc.
Input Format
Two integers a and b.
Output Format
Values of a after applying compound assignment operators.
Example
a = 20 b = 5
After += a = 25 After -= a = 15 After *= a = 100 After /= a = 4 After %= a = 0
Constraints
• Integer values
• b should not be 0 for /= and %=
• b should not be 0 for /= and %=
Concept Explanation
Compound assignment operators update a variable using its current value.
They are shorter and cleaner than writing full expressions.
Used in real life for things like bank balance updates or game scores.

Step-by-Step Explanation
1.Start with values a and b.
2.a += b → same as a = a + b.
3.a -= b → same as a = a - b.
4.a *= b → same as a = a * b.
5.a /= b → same as a = a / b.
6.a %= b → same as a = a % b.
7.Print value of a after each operation.
2.a += b → same as a = a + b.
3.a -= b → same as a = a - b.
4.a *= b → same as a = a * b.
5.a /= b → same as a = a / b.
6.a %= b → same as a = a % b.
7.Print value of a after each operation.

Input / Output Format
Input Format
Two integers a and b.
Output Format
Values of a after applying compound assignment operators.
Constraints
• Integer values
• b should not be 0 for /= and %=
• b should not be 0 for /= and %=
Examples
Input:
a = 20
b = 5
Output:
After += a = 25
After -= a = 15
After *= a = 100
After /= a = 4
After %= a = 0
Example Solution (Public)
void operator_q5_assignment() {
int num = 10;
cout << "Initial value: " << num << endl;
num += 5; // num = num + 5
cout << "After += 5: " << num << endl;
num -= 3; // num = num - 3
cout << "After -= 3: " << num << endl;
num *= 2; // num = num * 2
cout << "After *= 2: " << num << endl;
num /= 4; // num = num / 4
cout << "After /= 4: " << num << endl;
}
Official Solution Code
