Embedded C lo Operators Explained in Telugu

📌 Introduction:

Embedded C lo manam calculations, decisions, and comparisons chese prathi step lo operators ni vadatam jarugutundi. Operators ante symbols or keywords vi, which perform specific actions.

I article lo most used operators ni simple Telugu + English lo explain chestham.

🔹 1. What is an Operator?

Operator ante:
→ Variables or values meeda maths / logic / comparison chese tools.

Example:

int a = 10 + 5; // '+' is an operator

🔹 2. Types of Operators in Embedded C

Type	Description	Example
Arithmetic	+, -, *, /, %	a + b
Relational	>, <, >=, <=, ==, !=	a > b
Logical	&&,
Assignment	=, +=, -=, *=, /=	a += 1;
Bitwise	&,	, ^, <<, >>
Increment/Decrement	++, --	i++; or i--

🔹 3. Arithmetic Operators

int a = 10, b = 5;
int sum = a + b;      // 15
int mul = a * b;      // 50
int mod = a % b;      // 0

👉 Useful for sensor values, counters, delay calculations.

🔹 4. Relational Operators (Compare values)

if (temp > 100) {
    // Overheating alert
}

 Real-time devices lo threshold check cheyataniki use avutayi.

🔹 5. Logical Operators (AND, OR, NOT)

if (temp > 50 && fanOn == 1) {
    // Turn off heater
}

👉 Multiple conditions handle cheyyadam ki use chestaru.

🔹 6. Bitwise Operators (very important in embedded)

PORTA = PORTA & 0x0F; // Lower nibble retain cheyyadam
PORTA = PORTA | 0xF0; // Upper nibble set cheyyadam

👉 Registers, ports, hardware control logic lo ekkuva use avutayi.

🔹 7. Increment & Decrement

i++;  // i = i + 1
i--;  // i = i - 1

👉 Loops and counters lo frequent ga use chestaru.

✅ Conclusion:

Operators are the heart of logic in Embedded C.
Prathi operator ni correct place lo vadithe:

• Code clean & efficient avutundi

• Memory and performance improve avutayi
