Problem Solving Through C (BCA) 1st Sem Previous Year Solved Question Paper 2022

There are various arithmetic and assignment operators for performing mathematical operations and assigning values to variables. Here are some of the most common operators along with examples:

Arithmetic Operators:

1. Addition ‘ + ‘: Adds two operands.

int result = 5 + 3; // result is now 8

2. Subtraction ‘ - ‘: Subtracts the right operand from the left operand.

int result = 10 - 4; // result is now 6

3. Multiplication ’ * ‘: Multiplies two operands.

 int result = 3 * 5; // result is now 15

4. Division ‘ / ‘: Divides the left operand by the right operand.

  double result = 12.0 / 4; // result is now 3.0

5. Modulus ‘ % ‘: Returns the remainder of the division of the left operand by the right operand.

int result = 15 % 4; // result is now 3

 

Assignment Operators:

Assignment ‘= ‘: Assigns the value of the right operand to the left operand.

 int x = 5; // x is assigned the value 5

Addition Assignment ‘ += ‘: Adds the right operand to the left operand and assigns the result to the left operand.
int x = 5;

x += 3; // x is now 8

Subtraction Assignment ‘ -= ‘: Subtracts the right operand from the left operand and assigns the result to the left operand.

 int x = 10;

x -= 4; // x is now 6

Multiplication Assignment ’ *=’ : Multiplies the left operand by the right operand and assigns the result to the left operand.

 int x = 3;

x *= 5; // x is now 15

Division Assignment ’ /=’ : Divides the left operand by the right operand and assigns the result to the left operand.

 double x = 12.0;

x /= 4; // x is now 3.0

 
Modulus Assignment ‘ %= ’: Calculates the modulus of the left operand and assigns the result to the left operand.

 int x = 15;

x %= 4; // x is now 3
