C program to find transpose of a matrix

Hello I want to discuss about the c program for transpose of the matrix.
Transpose matrix means interchange the rows with the columns and columns with the rows.

Program Code

#include < stdio.h >
#include < conio.h >
void main()
{
int arr[3][3],i,j;
clrscr();
printf("Enter elements for the array \n");
for(i=0;i < 3;i++)
{
for(j=0;j < 3;j++)
{
scanf("%d",&arr[i][j]);
}
}
printf("Original array entered by the user is \n");
for(i=0;i < 3;i++)
{
for(j=0;j < 3;j++)
{
printf("%d ",arr[i][j]);
}
printf("\n");
}
printf("\n Transpose of the array is \n");
for(i=0;i < 3;i++)
{
for(j=0;j < 3;j++)
printf("%d ",arr[j][i]);
printf("\n");
}
getch();
}

Input:

Enter elements for the array
1
2
3
4
5
6
7
8
9

Output:

Original array entered by the user is
1 2 3
4 5 6
7 8 9

Transpose of the array is
1 4 7
2 5 8
3 6 9

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();
}
