Write a C program in ‘c’ to find given positive number is prime number or not.

Write a C program in ‘c’ to find given positive number is prime number or not. 

Ans:
#include<stdio.h>
#include<conio.h>
void main()
{
int I,n;
int ctr=0;
printf(“enter any no\n”);
scanf(“%d”&n);
for(i=1;<=n;i++)
{
if(n%i==0)
{
ctr++;
}
}
if(ctr==2)
{
printf(“%d is prime no\n”);
}
else
{
printf(“%d is not a prime no\n”);
}
getch();


write a recursive function to reverse a string

//write a recursive function to reverse a string
#include<stdio.h>
#include<conio.h>
void main()
{
 void reverse();
 clrscr();
 printf("enter any string\n");
 reverse();
 getch();
// scanf("%d");//but we need to enter any value or letter to see o/p
}
//
void reverse()
{
 char ch;
 ch=getchar();
 if(ch!='\n')
 {
  reverse();
  printf("%c",ch);
  //putchar(ch);
  }
 }

write a recursive function for n

write a recursive function for n

long double fact(int n)
{
 if(n>0)
  return(n*fact(n-1));
 else
  return(1);
}
main()
{
 int n;
 long double fact(int);
 printf("enter any +ve integer (or) 0\n");
 scanf("%d",&n);
 printf("%d!=%Lf\n",n,fact(n));
 getch();
}

Output:


1. Enter the number : 5 Factorial of number: 120 

2. Enter the number : 3 Factorial of number: 6 

3. Enter the number : 9 Factorial of number: -30336 

Conclusion: the program is error free




VIVA QUESTIONS:

1)  What is the meaning of factorial number?
  Ans : Factorial of a number is nothing but the multiplication of numbers from
            a given number to 1

2) What is the meaning of recusive function ?    
    Ans: A function call it self is called recursive function 


3) Define library functions ? 
  Ans: The functions have already been written, compiled and placed in libraries and are called library functions.

4)  Define formal parameters ?
  Ans: Formal parameters are the parameters given in the function declaration as function definition.
