Chapter 1 : Introduction to C

What is Programming?

Programming is the process of giving instructions to a computer.

Programming म्हणजे संगणकाला सूचना देण्याची प्रक्रिया.

What is C?

C is a general-purpose programming language developed by Dennis Ritchie in 1972.

Advantages of C

• Fast
• Portable
• Structured
• Efficient

Program 1 : Hello World

#include

int main()
{
 printf("Hello World");
 return 0;
}

Output

Hello World

Explanation

printf() is used to display output.

---

Chapter 2 : Variables & Data Types

Variable

A variable is a container used to store data.

int age=20;
float salary=15000;
char grade='A';

Program : Store Age

#include

int main()
{
 int age;

 printf("Enter Age : ");
 scanf("%d",&age);

 printf("Age=%d",age);

 return 0;
}

Output

Enter Age : 25
Age=25

---

Chapter 3 : Operators

Arithmetic Operators

• +
• -
• *
• /
• %

Program : Addition

#include

int main()
{
 int a,b;

 scanf("%d%d",&a,&b);

 printf("%d",a+b);

 return 0;
}

Output

30

Practice Set

1. Addition
2. Subtraction
3. Multiplication

Chapter 4 : Conditional Statements

if

if(condition)
{
}

Program : Even Odd

#include

int main()
{
 int n;

 scanf("%d",&n);

 if(n%2==0)
 printf("Even");
 else
 printf("Odd");

 return 0;
}

Output

Enter Number : 10
Even

Chapter 5 : Loops

Entry Controlled Loop

• for
• while

Exit Controlled Loop

• do while

Program : Print 1 to 10

for(i=1;i<=10;i++)
{
 printf("%d",i);
}

Output

1 2 3 4 5 6 7 8 9 10

Practice Set

1. Table
2. Factorial
3. Fibonacci
4. Reverse Number

{
 printf("Hello");
}

Recursion Example

factorial(n)
{
 if(n==1)
 return 1;

 return n*factorial(n-1);
}

---

Chapter 7 : Arrays

int marks[5];

Program : Sum of Array

#include

int main()
{
 int a[5]={10,20,30,40,50};
 int i,sum=0;

 for(i=0;i<5;i++)
 sum=sum+a[i];

 printf("%d",sum);
}

---
