C program to Print Inverse of a given Number

Inversing of a given Number. suppose we gave input 123456 then the output of the program will be 654321.

//C program to print inverse of a given number

#include<stdio.h>

#include<conio.h>

void main()

{

long int n,rn=0,d=0;

clrscr();

printf(“Enter the number\n\n”);

scanf(“%ld”,&n);

while(n>0)

{

d=n%10;

rn=rn*10+d;

n=n/10;

}

printf(“%ld”,rn);

getch();

}

c program for to find Prime Number

A prime number (or a prime) is a natural number that has exactly two distinct natural number divisors: 1 and itself.

the prime numbers under 100:

2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89, 97.

code:

//To Print Prime no. till limit

#include<stdio.h>

#include<conio.h>

void main()

{

int i,n,c=1;

clrscr();

printf(“Enter the limit\n\n”);

scanf(“%d”,&n);

while (c<=n)

{

i=2;

while(i<=c)

{

if(c%i==0)

break;

i++;

}

if(i==c)

printf(“\n%d”,c);

c++;

}

getch();

}

c program for Fibonacci Series

Fibonacci number

In mathematics, the Fibonacci numbers are the numbers in the following integer sequence:

1, 1, 2, 3, 5, 8, 13, 21, 34,55,89,144,……

C program to print number’s till limit, Except those that are divisible by 8

Factorial Program

In mathematics, the factorial of a positive integer n, denoted by n!, is the product of all positive integers less than or equal to n.

For example, 5 ! = 5 * 4* 3 * 2* 1 = 120

Using While Loop

type 1:

//Program for Factorial
#include<stdio.h>
#include<conio.h>
void main()
{
int n,fact=1;
clrscr();
printf(“Enter any Number:\n\n”);
scanf(“%d”,&n);
while(n>1)
{
fact=fact*n;
n–;
}
printf(“\nFactorial is=%d”,fact);
getch();
}
