C program for matrix multiplication of two matrix

Hello everybody I want to discuss the source code for matrix multiplication in c programming.

Program Code


//C program for multiplication of two matrix
#include < stdio.h >
#include < conio.h >
void main()
{
 int a[3][3], b[3][3], c[3][3], i, j, k;
 clrscr();
 printf("Enter the elements of first 3x3 matrix");
 for (i = 0;i < 3; i++)
 {
  for (j = 0; j < 3; j++)
  {
   scanf("%d",&a[i][j]);
  }
 }
 printf("\nEnter the elements of second 3x3 matrix");
 for(i = 0; i < 3; i++)
 {
  for (j = 0; j < 3; j++)
  {
   scanf("%d", &b[i][j]);
  }
 }
 printf("\nThe first matrix is :-\n");
 for (i = 0; i < 3; i++)
 {
  for (j = 0; j < 3; j++)
  {
   printf("\t%d", a[i][j]);
  }
  printf("\n");
 }
 printf("\nThe second matrix is :-\n");
 for (i = 0; i < 3; i++)
 {
  for (j = 0; j < 3; j++)
  {
   printf("\t%d", b[i][j]);
  }
  printf("\n");
 }

 printf("\nMultiplication of the two matrices is as follows:\n");
 for (i = 0;i < 3; i++)
 {
  printf("\n");
  for (j = 0; j < 3; j++)
  {
   c[i][j]=0;
   for(k=0;k<3;k++)
   c[i][j] = c[i][j]+a[i][k] * b[k][j];
   printf("\t%d", c[i][j]);
  }
 }
 getch();
}

C Program For Fibonacci Series

Hello everybody I want to discuss about How to generate a Fibonacci series in C programming.

What is Fibonacci Series?

The first two Fibonacci numbers are 0 and 1 then next number is addition of previous two numbers.

0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89.....
In mathematics it is defined by recurrence relation.

Program Code

  


//C Program for generate Fibonacci series
#include "stdio.h"
#include "conio.h"
void main()
{
 int a,b,c,i,n;
 clrscr();
 a=0;
 b=1;
 printf("\n enter n for how many times generate series");
 scanf("%d",&n);
 printf("\n FIBONACCI SERIES\n");
 printf("\t%d\t%d",a,b);
for(i=0;i<n;i++)
{
     c=a+b;
     a=b;
     b=c;
     printf("\t%d",c);
 }
 getch();

c program to check number is prime or not

Program Code

// Check whether given number is prime number and not prime number
#include "stdio.h"
#include "conio.h"
void main()
{
int num,i,z;
printf("enter the value of num");
scanf("%d",&num);
i= 2;
while (i less then num)
{
if(num%i==0)
{
z=1;
}
i=i+1;
}
printf("After checking the result is");
if(z== 1)
{
printf("given number is not prime number");
}
else
{
printf("given number is prime number");
}
getch();
}

Input/Output

enter the value of num 7
After checking the result is
given number is prime number

What is Prime Number?

Prime number is a natural number which is divisible by 1 and itself.
Example 7

First 25 Prime Number :-
2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89, 97

C Program to check number is palindrome or not

C Program Code

//Check number is palindrome of not
#include "stdio.h"
#include "conio.h"
void main()
{
int num,rev=0,m,r;
clrscr();
printf("enter any number");
scanf("%d",&num);
m=num;
while(num>0)
{
r=num%10;
rev=rev*10+r;
num=num/10;
}
if(rev==m)
printf("given number is palindrome");
else
printf("given number is not palindrome");
getch();
}

Input/Output

enter any number 121
given number is palindrome

enter any number 423
given number is not palindrome

What is Palindrome No?

when we read a number. If backward read is as same as forward read then number is palindrome.

How to Redirect in html

To redirect in html here is the simple one line meta tag code:


< meta HTTP-EQUIV="REFRESH" content="0; 
url=http://sampleexamples.com/" >

Add this code in html < head > tag.
you can specify time interval like:


content="5; url=http://sampleexamples.com/"

Here 5 represents 5 seconds means it will redirect after 5 sec. to sampleexample.com.
