Post ur C/C++ Programs Here
Filed Under mercialleasing.com |
If you are a good at C/C++ Programming or if you are a programmer or just know this language then post you Programs here. By this way it helps learners a lot. Members can post their programs and get suggestions if there is anything wrong it......
Use this Pattern:
A Program to find the largest of three numbers using nested if
#include
main()
{
int a,b,c,big;
printf("Enter Three numbers");
scanf("%d%d%d",&a,&b,&c);
if(a>b)
if(a>c)
big=a;
else
big=c;
else
if(b>c)
big=b;
else
big=c;
printf("Largest of %d,%d and %d = %d",a,b,c,big);
return 0;

I find books by Yashavant Kanetkar the best ones for C/C++.
can someone tell me what's wrong in this program.Using Dev C++
Either Sykora's solution or simply add a float to your function definition line:
#include
using namespace std;
int main()
{
/*Use of Function*/
float a,b,sum;
float calsum(float a,float b);
cout<<"Enter the two nos.:n";
cin>>a>>b;
sum=calsum(a,b);
cout<<"The sum is :"<
return 0;
}
float calsum(float a,float b)
{
float sum;
sum=a+b;
return (sum);
}
New to c++.......Whta those this line means
y r u using scanf in c++???
I recommend a decent and recent C++ book, like C++: How To Program, C++ Primer, 4th/e or C++ Primer Plus.
hmm, u use Oxford and Sumita Arora's textbook for C++. they're our course books in XI and XII

PLz tell me what about this program and what it will do, i know stack but plz explain
I have new idea..!!!!
What about some challenges any one can raised problem, before 2 days my teacher challenge me to do a program to convert given number into binary , octal and hexadecimal. I have found solution but you have to try.
for exercise:
do a program like U have to hide the typed string on screen by" * "
like we do **********
nice one haa..

conio.h is non-standard.
Your calsum() doesn't have a forward declaration. Put main() after calsum() or put the line :
int calsum(float, float);
before main().

bad math funda :D .. iterate from 2 to (int)sqrt(n) ..if it isnt divisible then itz prime
Who told you that? I recommend what I use - Lafore's, Prata's, Lippman's and Stroustrup's.
How to Program in C++ by Deitel and Deitel is good too
I find books by Yashavant Kanetkar the best ones for C/C++.
And as far as Kanetkar is concerned ... when I was inmy 11/12th I thought so too. But now, :D u jst mature. Those books feel like being fed with a spoon.
They do contain a LOT of funda though
i had made this one for a friend - it was his project

Write a program using functions to find whether the given number is a prime number?
Rules of programming:
1. Read the fscking code. And mine is pretty readable.
2. Test it before complaining.
3. If you still don't get it, it's time to buy a decent C book.
I know the variable names are quite big. But I think that makes it easier to understand the program without comments.
I am new to C++. So, if you can suggest any improvements, then please do so.
One more thing, from my experience, Indian authors tend to provide knowledge based on TurboC which sucks. So, anyone going for a C++ course, please get a book suggested above, and then be sure to read professional C++ by Solter and Kleper (Wrox international). It rocks.

To add an element to it, we can only push from top and not insert anywhere we like:
So after pushing 10 into the stack, it looks like:
10 <-- (Pushed on top)
20
30
40
----
Similarly, as its a LIFO system, Popping the stack removes the top most element.
Thus, 10 would be removed on popping:
20 --> 10 (Popped out and deleted)
30
40
----
Stack's best application would be the function call. Recursion takes place in stacks format. (And are thus usually avoided)

can someone tell me what's wrong in this program.Using Dev C++

float a,b,sum;
float calsum(float a,float b);

cout<<"The sum is :"<
calsum(float a,float b)
{ float sum;
sum=a+b;
return (sum);
}
use this thread to request programs and then pm to the requester rather than posting so much code over here it really looks a mess and these are quite basic too
main()
{
int a,b,c,big;
printf("Enter Three numbers");
scanf("%d%d%d",&a,&b,&c);
if(a>b)
if(a>c)
big=a;
else
big=c;
else
if(b>c)
big=b;
else
big=c;
printf("Largest of %d,%d and %d = %d",a,b,c,big);
}
Your program lacks proper braces and a return statement.
here's a prog to calc area, surface area, volume, total surface area etc. of numerous 2D and 3D figures using functions

...
i've put up a lot more progs at my forum. classmates really find it useful since none of them is interested in computers. its so sad...
Your code doesn't conform to either ISO C or C++ standards.
scanf("%d%d%d",&a,&b,&c);
New to c++.......Whta those this line means
scanf() is a C input function, which is considered unsafe except for formatted data. I advise learning C first, before opting for a much larger, bloated and complex language as C++.
Mate i suggest you re-learn C++ using Addison Wesley's Accelerated C++
One of the best Standard C++ books out there that actually teach you how to use STL practically rather than just theory.
btw , i read this in class XI(i'm currently in XII) so ditch your textbook(seriously) and use this .
Like system("shutdown /?"); for example.
Why would you wanna do it though ? I smell a prank :D
Try this:
#include
int main(void)
{
int a = 0,
b = 0,
c = 0,
greatest = 0;
printf("Enter three numbers:n");
scanf("%d %d %d", &a, &b, &c);
greatest = a;
if(b > greatest)
greatest = b;
if(c > greatest)
greatest = c;
printf("greatest of %d, %d and %d = %d", a, b, c, greatest);
return 0;
}

Who told you that? I recommend what I use - Lafore's, Prata's, Lippman's and Stroustrup's.
Using implementation dependent libraries and functions like clrscr(), and the nonstandard "void main()" violates the rules of the ISO C++ standard. Your executable may run fine on a system, but your code needs more love.
I recommend a decent and recent C++ book, like C++: How To Program, C++ Primer, 4th/e or C++ Primer Plus.

What about some challenges any one can raised problem, before 2 days my teacher challenge me to do a program to convert given number into binary , octal and hexadecimal. I have found solution but you have to try.
That is one helluva program which I made 2-3 months back but my program was not perfect as I used a lot of arrays which took up a lot of memory and more often than not they were never used.I seem to have lost my original program code but will write it and post it in a couple of days or so.
YOu can actually display the given no. in octal,hexadecimal,and binary by just using %o,%x,and(I forgot for binary) instead of %d while displaying.
