Some basic C language program using while loop ,study easy

1- Write a program to print table for the given number using while loop in C language. 

While loop concept program

#include<stdio.h>

#include<conio.h>

int main()

{

int i=1, number ;

clrscr();

printf(“Enter a number :”);

scanf(“%d”,&number);

while(i<=10)

{

Printf(“%d\n”,(number * i));

I++;

}

getch();

}

Output:-

Enter a number: 5

5 10 15 20 25 30 35 40 45 50

Write a program in C language using for loop.

2-write a c lamguage program to print 1 to 10 numbers using while loop.

#include<stdio.h>

#include<conio.h>

int main()

{

int i=1;

while(i<=10)

{

printf(“%d ”, i );

i++;

}

getch();

}

Output:- 1 2 3 4 5 6 7 8 9 10

Program in c language using if-else condition.

3-write a c lamguage program to print “Hello world!” using while loop.

#include<stdio.h>

#include<conio.h>

int main()

{

int i=1;

while(i<=5)

{

printf(“Hello world!” );

i++;

}

getch();

}

Output:- Hello world! Hello world! Hello world! Hello world! Hello world!

::-Armstrong Number:-

Armstrong Number is a number that is equel to the sum of cubes of its all digits.

Example- 0, 1, 153, 370, 371, 407 …….

4-Write a program in c language to check Armstrong Number.

#include<stdio.h>

#include<conio.h>

int main()

{

int n, r, sum=0, temp;

clrscr();

printf(“Enter the number=”);

scanf(“%d”, &n);

temp=n;

while(n>0)

{

r=n%10;

sum = sum+ (r*r*r);

n=n/10;

}

if ( temp= =sum )

printf(“Armstrong number”);

else

printf(“Not Armstrong number”);

getch();

}

Output:-

Enter the number= 153

Armstrong number

Write a C-language program for Addition,Substraction,Multiplication and Division.

5- Write a program in C language for Factorial of a number.

#include<stdio.h>

#include<conio.h>

void main()

{

int n, i=1, f=1;

clrscr();

printf(“\n Enter a number for factorial:-”);

scanf(“%d”,&n);

while(i<=n)

{

f=f * i ;

i++;

}

printf(“ The Factorial of %d is %d”,n, f);

getch();

}

Output:- Enter a number for factorial:- 6

The Factorial of 6 is 720

6- Write a program to print table for the given number using while loop in C++ language.

#include<iostream.h>

using namespace std;

int main()

{

int i=1, number ;

clrscr();

cout<<“Enter a number :”;

cin>>(“%d”,&number) ;

while(i<=10)

{

cout<<“%d\n”,(number * i) ;

I++;

}

getch();

}

Output:-

Enter a number: 2

2 4 6 8 10 12 14 16 18 20
