What is Recursion in C ? And How it is use

/*

Hello friends !
I am Manish Gupta.
And welcome to you all at https://www.blogger.com/profile/11710251641564278815 (manishnips.net)

How are you ?
In this page I describe  Introduction of Recursion in Function and also describe the program of Function.

C programming के इस tutorial series में मैंने program लिखने और compile करने के steps बताएं हैं| मुझे उम्मीद है की यह पोस्ट आपके लिए काफी हेल्पफुल होगा| इस पोस्ट को अपने दोस्तों के साथ जरुर share करें| manishnips blog पर आने के लिए धन्यवाद|

                                                    RECURSION

# Recursion is a process in which function calls itself its body.
# It is used for Repeatetive task.
    Rules for Recursion:-1. Function must be called or invoked itself in its body.
2. Their must be an exit condition to stop Recursion.
    Types of Recursion:-
There are Two types of Recursion1. Direct Recursion:-When function calls itself in its body.ie- only one function is invoked.
Example:void num()
{
..........
..........
num();
}
2.Indirect Recursion:-For indirect Recursion two function are involed. Both call each other in their body.
Example-void num()
{
............
............
sum();
}
{
............
............
num();
}

अगर आप programming के field में अपना carrier बनाना चाहते हैं तो आपको सबसे पहले Recrtsion के basics को सीखना होगा उसके बाद ही आपको बड़े बड़े program समझ आयेंगे|

Que.. WAP to find factorial of input nos. using Recursion.

#include<stdio.h>
#include<conio.h>
int fact(int );
void main()
{
int n,t;
clrscr();
printf("Enter any number=");
scanf("%d",&n);
t=fact(n);
printf("Factorial=%d",t);
getch();
}
int fact(int x)
{
int z;
if(x==0)
return 1;
else
{
z=x*fact(x-1);
return z;
}
 }
Que... WAP to print table of inpur nos . using Recursion. 

#include<stdio.h>
#include<conio.h>
void table(int,int);
void main()
{
int n;
clrscr();
printf("Enter any no=");
scanf("%d",&n);
table(1,n);
getch();
}
void table(int x,int y)
{
if(x==10)
printf("\n%d",x*y);
else
{
printf("\n%d",x*y);
table(++x,y);
}
}

This is dummy text. It is not meant to be read. Accordingly, it is difficult to figure out when to end it. But then, this is dummy text. It is not meant to be read. Period.
