Write a C program to find the factorial of a number using recursion.

#include
#include
int fact(int);
void main()
{
int num,fact1;
printf("Enter a value of num");
scanf("%d",&num);
fact1=fact(num);
printf("factorial=%d",fact1);
getch();
}
int fact(int n)
{
int f=1;
if(n==0)
{
return 1;
}
else
{
f=n*fact(n-1);
return(f);
}
}

Write a program to find fibonacci series in c using recursion.

#include
#include
int fiab(int);

void main()
{
int i,n;
clrscr();
printf("How many terms do you wish to find?\n");
scanf("%d",&n);

printf("\nThe Series is : \n");

for(i=1;i<=n;i++)
{
printf(" %d \n",fiab(i));
}

getch();
}

int fiab(int n)
{
if(n==1||n==2){
return 1;}
else{
return(fiab(n-1)+fiab(n-2));}
return 0;
}
