#include<stdio.h>
#include<conio.h>
void add(int *a);
main()
{
int
value,x,y,z,a,b,c;
scanf("%d",&value);
a=value/100;
printf("no
of 100th %d",a);

(a) Write a function to
calculate the factorial value of any integer entered through the keyboard.
(b) Write a function power
( a, b ), to calculate the value of a raised to b.
#include<stdio.h>
#include<conio.h>
int power(int a,int b);
main()
{
int a,b,f;
scanf("%d",&b);
scanf("%d",&a);
f=power(a,b);
printf("%d",f);
getch();
}
int power(int a,int b)
{
int
c,lov=1;
for(c=1;c<=b;c++)
{lov=lov*a;}
return lov;
}
(c) Write a
general-purpose function to convert any given year into its roman equivalent.
The following table shows the roman equivalents of decimal numbers:
Example:
Roman equivalent of 1988 is mdcccclxxxviii
Roman equivalent of 1525 is mdxxv
(d) Any year is entered
through the keyboard. Write a function to determine whether the year is a leap
year or not.
(e) A positive integer is
entered through the keyboard. Write a function to obtain the prime factors of
this number
Write a recursive function to obtain the first 25 numbers of a
Fibonacci sequence. In a Fibonacci sequence the sum of two successive terms
gives the third term. Following are the first few terms of the Fibonacci
sequence: 1 1 2 3 5 8 13 21 34 55 89...
#include<stdio.h>
#include<conio.h>
int power(int n);
main()
{
int a=0,b=1,n;
scanf("%d",&n);
power(n);
getch();
}
int power(int n)
{
int
c,a=0,b=1;
printf("%d",b);

printf("%d",c);
a=b;
b=c;

}
Write a program to pick up
the largest number from any 5 row by 5 column matrix.

#include<conio.h>
main( )
{
int a
[3][3],i,j,b;
for(i=0;i<=2;i++)
for(j=0;j<=2;j++)

for(j=0;j<=2;j++)
{
if(b<a[i][j])
b=a[i][j];}
printf("%d",b);
getch();
}
Write a program to obtain
transpose of a 4 x 4 matrix. The transpose of a matrix is obtained by
exchanging the elements of each row with the elements of the corresponding
column
#include<stdio.h>
#include<conio.h>
main( )
{
int a
[3][3],i,j,b;
for(i=0;i<=2;i++)
for(j=0;j<=2;j++)
scanf("%d",&a[i][j]);
for(j=0;j<=2;j++)
{
for(i=0;i<=2;i++)
{
printf("\t%d",a[i][j]);}
printf("\n");}
getch();
}

6 x 6 matrices.
# include<stdio.h>
# include<conio.h>
main()
{
int
a[3][3],b[3][3],c[3][3],i,j;
printf("Enter the
elements of a matrix");
for(i=0;i<=2;i++)
for(j=0;j<=2;j++)
scanf("%d",&a[i][j]);
printf("elements of
2nd matrix are\n");
for(i=0;i<=2;i++)
for(j=0;j<=2;j++)
scanf("%d",&b[i][j]);
printf("sum of two
materices are\n");
for(i=0;i<=2;i++)
{
for(j=0;j<=2;j++)

printf("%d\t",c[i][j]);
}
printf("\n");
}
getch();
}
(2) Write a program to
multiply any two 3 x 3 matrices.
# include<stdio.h>
# include<conio.h>
main()
{
int a[3][3],b[3][3],c[3][3],i,j,k,sum=0;
printf("Enter the elements of a matrix");
for(i=0;i<=2;i++)
for(j=0;j<=2;j++)
scanf("%d",&a[i][j]);
printf("Enter the second matrix\n");
for(i=0;i<=2;i++)
for(j=0;j<=2;j++)
scanf("%d",&b[i][j]);
printf("Multiplication of materix are\n");
