💡 Real Life Example: ATM machine lo - Screen meeda chupinchadam Output, Pin kotadam Input - Ade C lo kuda!

1. printf() - Output Function

printf() = Print Format - Screen meeda emaina chupinchali ante printf() vadali.

    scanf("%d", &b);
    
    sum = a + b;
    
    printf("Sum = %d", sum);
    
    return 0;

Variables and Data Types in C Language in Telugu | C Programming Part-2

Variables & Data Types in C Language | Telugu lo Easy ga

Part-2: C Basics Strong cheskundam - LearnTechSoft

📌 Last Post lo: C Language ante enti telusukunnam. Ippudu Variables & Data Types nerchukundam.

1. Variable ante enti?

Variable = Container - Data ni store chese dabba lanti di. Prati variable ki oka name untundi, oka value untundi.

Example: Mee intlo dabbalu unnai kada? Pappu dabba, Uppu dabba - Ade Variable!
int age = 25; - Ikkada age anedi dabba peru, 25 anedi lopala unna value.

2. Rules for Variable Name

• Letter (a-z) or Underscore (_) tho start avali - Number tho start avvakudadu
• Space undakudadu - my age ❌ my_age ✅
• Capital & Small different - Age and age rendu veru veru
• Keyword vadakudadu - int, float lanti vi peru ga pettakudadu

3. Data Types in C - 4 Main Types

Data Type	Size	Example	Use
int	4 bytes	10, -5, 100	Numbers kosam
float	4 bytes	3.14, 5.5	Point numbers
char	1 byte	'A', 'x'	Single letter
double	8 bytes	3.1415926	Big point numbers

4. Live Example Program

#include <stdio.h>

int main() {
    // Variables Declaration
    int age = 22;
    float marks = 85.5;
    char grade = 'A';
    
    printf("Age: %d\n", age);
    printf("Marks: %.1f\n", marks);
    printf("Grade: %c\n", grade);
    
    return 0;
}

Output:
Age: 22
Marks: 85.5
Grade: A

5. Format Specifiers - Chala Important!

%d
for int

%f
for float

%c
for char

%lf
for double
