The document outlines various simple coding programs, including printing 'hello world', calculating the addition of two numbers, and computing simple interest. It contains code snippets in C language for each program example, detailing user input and expected output. The document concludes with a note of thanks.

1. C - Coding

2. Programs :
Program to print
"Hello World!!".
01
Program to
assign values of
two numbers and
print their
addition
02
Program to
accept values of
two numbers and
print their
addition.
03
Program to print
simple interest.
04
Program to
accept value of
radius and print
area of a circle.

3. Program 1:
clrscr();
#include<stdio.h>
#include<conio.h>
void main()
{
int a=10,b=20;
int ans = a + b;
printf("Addition is : %d",ans);
}

4. Program 3:
#include<stdio.h>
#include<conio.h>
void main()
{
int a,b,ans;
printf("Enter 1st number:");
scanf("%d",&a);
printf("Enter 2nd number:");
scanf("%d",&b);
ans = a + b;
printf("Addition is : %d",ans);

5. Program 4:
#include<conio.h>
void main()
{
float interest, p, r, n;
printf("Enter value of P: ");
scanf("%f",&p);
printf("Enter value of R: ");
scanf("%f",&r);
printf("Enter value of N: ");
scanf("%f",&n);
interest=p*r*n/100f;
printf("Simple Interest : %f", interest);

6. Program 5:
#include<conio.h>
scanf("%f",&radius);
