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++.
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 .

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..
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;
}

----
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)

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...
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.
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.
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

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++.
Write a program using functions to find whether the given number is a prime number?
#include
main()
{
long rev, n, num;
int digit;
printf("n Enter a number");
scanf("%d", &num);
rev=0;
n=num;
while (num>0)
{
digit = num % 10;
num = num / 10
rev = rev * 10 + digit;
}
printf("n The number is %d", n);
printf("n The reverse is %d", rev);
}
New to c++.......Whta those this line means
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().
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.
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
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 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
Don't be so hard on him :D He doesn't know TC++'s evils :D
Anyway, here's xbonez's program in proper code :)

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.

Either Sykora's solution or simply add a float to your function definition line:

float sum;
sum=a+b;
return (sum);
