DO WHILE LOOP

By
       
  1.   1.TABLE IF ONE:

#include<stdio.h>
int main()
{
int i=1;
do
{
printf("%d\n",i);
i++;
}
while(i<=10);
}
•OUTPUT 

1
2
3
4
5
6
7
8
9
10

 2.PRINT DIGITS OF INTEGER VALUE IN REVERSE ORDER: 

#include<stdio.h>
int main()
{
int no,b;
printf("Enter any number\n");
scanf("%d",&no);
printf("Reverse is given below\n");
do
{
b=no%10;
printf("%d",b);
no=no/10;
}
while(no!=0);
}
•OUTPUT 

Enter any number 
589
Reverse is given below
985

3.CHECK NUMBER IS PALINDROME OR NOT :


#include<stdio.h>
int main()
{
int no,b,rev=0,cpy;
printf("Enter any number\n");
scanf("%d",&no);
cpy=no;
do
{
b=no%10;
rev=rev*10+b;
no=no/10;
}
while(no!=0);
if(cpy==rev)
printf("Palindrome");
else
printf("Not Palindrome");
}
•OUTPUT 

Enter any number 
5885
Palindrome 

                           4.FIND SUM OF DIGITS OF INTEGER VALUE: 


#include<stdio.h>
int main()
{
int no,b,sum=0;
printf("Enter any number\n");
scanf("%d",&no);
do
{
b=no%10;
sum=sum+b;
no=no/10;
}
while(no!=0);
printf("Total sum of digits=%d",sum);
}
•OUTPUT 

Enter any number 
785
Total sum of digits=20

                        5.FIND MULTIPLY OF DIGITS OF INTEGER NUMBER: 



#include<stdio.h>
int main()
{
int no,b,m=1;
printf("Enter any number\n");
scanf("%d",&no);
do
{
b=no%10;
m=m*b;
no=no/10;
}
while(no!=0);
printf("Total multiply of digits=%d",m);
}
•OUTPUT 

Enter any number 
325
Total multiply of digits=30

                      6.PRINT FIRST AND LAST DIGIT OF INTEGER NUMBER: 


#include<stdio.h>
int main()
{
int no,b,f;
printf("Enter any number\n");
scanf("%d",&no);
f=no%10;
do
{
b=no%10;
no=no/10;
}
while(no!=0);
printf("First digit=%d and last digit=%d",b,f);
}
•OUTPUT 

Enter any number 
4859
First digit=4 and
Second digit=9

Java vs C++

By
S No. Parameters C++ Java 1. Platform Dependency C++ is platform dependent language.    Java is platform independent language. 2. Platform Philosophy Write once, compile anywhere (WOCA).    Write once, run anywhere / everywhere (WORA / WORE). 3. Developer Bjarne Stroustrup , 1980 James Gosling, Patrick Naughton, Chris Warth, Ed Frank & Mike Sheridan at Sun Microsystems, in 1991. 4. Original Name Originally named as "C with Classes" by Bjarne Stroustrup, renamed to "C++" (indicating an increment to C) which is proposed by Rrick Mascitti in 1983. Originally named as "Oak" by James Gosling, renamed to "Java" 1995. 5. Evolution C++ is a superset of C. C++ is evolved from C & simula67. Java is neither a superset nor a subset of C & C++. It takes some features from C & C++ and also includes some new features too. 6. Language level C++ is a middle-level language. Java is a high-level language. 7. Extensions C++ files have extension .cpp ...

SWITCH PROGRAMME

By

      ☆SWITCH PROGRAMME LIST☆ What is a switch Statement in C? The switch case statement is used when we have multiple options and we need to perform a different task for each option.when the variable being switched on is equal to a case,the statements following that case will execute until a break statement is reached. When a break statement is reached the switch terminates,and the flow of control jumps to the next line after the switch statement.Not every case needs to contain a break .if no break appears , the flow of control will fall through to subsequent cases until a break is reached.  The if..else..if ladder allows you to execute a block code among many alternatives. If you are checking on the value of a single variable in if...else Ladder , it is better to use switch statement. The switch statement is often faster than nested if...else (not always). Also, the syntax of switch statement is cleaner and easy to understand. The syntax of switch...case: When a ca...
