Answer
Hi Dimples

here is the entire program for you

#include<conio.h>
#include<stdio.h>
void fact(int no)
{
int i, fact = 1;
if(no>0)
{
printf("1");
for(i = 2 ; i<=no ; i++)
{
printf(" X %d",i);
fact = fact * i;
}
printf(" = %d",fact);
}
else
printf("Error !");

getch();
}

void fib(int no)
{
int a=0,b=1,c = 1,i;
if(no>0)
{
for(i=0;i<no;i++)
{
printf("%d", c);
c = a + b;
a = b;
b = c;
}
}
else
printf("Error !");
getch();
}

void main()
{
int ch, no;
do {
clrscr();
printf("Menu");
printf("\n Press 1 for Factorial");
printf("\n Press 2 for Fibonacci");
printf("\n Press 0 to Exit");
printf("\n Enter your choice: ");
scanf("%d",&ch);
if(ch == 1 || ch == 2)
{
printf("Enter a no: ");
scanf("%d",&no);
printf("\n\n\n\n");
if(ch==1)
fact(no);
else
fib(no);
}
}while(ch!=0);
}
