The best way to learn C programming is by practicing examples. This ppt contains examples on basic concepts of C programming. You are advised to take the references from these examples and try them on your own. All the programs on this ppt are tested and should work on all platforms.

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);
