Sry guyz actually i m in college hostel and internet wasn't working here .

So here is the answer-

void main()
{

int a,b;

cout<<"Ennter two numbers: ";
cin>>a>>b;
char c,d;

strcat(c,d);

cout<<Result= "<<strlen(c);
}

Here's the answer ---

Code Block

#include<iostream.h>
#include<stdlib.h>

void (*func[2])(int);

void main(int n=1)
{

int i;

cout<<endl<<n;

func[0]=&exit;
func[1]=&main;

i = ++n <= 10;

(func[i])(n);

}

This code prints numbers from 1 through 10.

Replace 10 with any positive number, and it would print the desired result.

this code worked for me..

Code Block

node * reverse (node *x)

{

node *temp;

if ( !(x && x -> next))

return x;

temp = reverse(x -> next);

x -> next -> next = x;
x -> next = NULL;

return temp;

}

*temp is a temporary node.

I've specified the required code only.

I've not specified the declaration of the list.

I hope that is understood.

Here's the answer ---

Code Block

int **temp,i,j;

temp = new int*[3];
for(i=0;i<3;i++)

  {
   temp[i][j] = arg1[i][j];   // COPY "arg1" to "temp"
   temp[i][j] += 5;          // INCREMENT each element of "temp" by "5"
   cout<<" "<<temp[i][j];     // DISPLAY "temp"
  }
  cout<<endl;
}
return temp;
}

void main()
{
clrscr();
int **a;
int i,j;
a = new int*[3];
for(i=0;i<3;i++)
  a[i] = new int[3];

dude u can do it using atoi function sry i don't have c or c++ here in my net lab so will give u answer in 2 days plz but try atoi fuction i think it will solve ur problem.

i will give u whole program this weekend sry for delayed answers

   n = atoi(str);
   printf("string = %s integer = %d\n", str, n);
   return 0;

Predict the output of the following :

Code Block

#include<iostream.h>

void main()

{int a=10,b;

b=(a++,a++,a++);

cout<<a<<" "<<b;

}

Next Question:-

How can you add Two number without using any operator ?

(either in c or c++)

I will provide the answer after 1 day.

how this is works

Saturday, October 6, 2007 12:38 PM

i like u very much

Saturday, October 6, 2007 12:41 PM

I think no way for if. Because when we try even with multiple compliment addition of binary we have to use binary oparator

Monday, October 8, 2007 6:45 AM

Sry guyz actually i m in college hostel and internet wasn't working here Sad .

So here is the answer-

void main()
{

int a,b;

cout<<"Ennter two numbers: ";
cin>>a>>b;
char c Angel ,d Beer ;

strcat(c,d);

cout<<Result= "<<strlen(c);
}

Monday, October 8, 2007 10:27 AM

Write a C++ program without using any loop (if, for, while etc) to print numbers.

I will give answer on monday in 2 days.

Do you mean numbers from 1 to n (say 100 ) ??

Sunday, October 14, 2007 5:21 AM

Here's the answer ---

Code Block

#include<iostream.h>
#include<stdlib.h>

void (*func[2])(int);

void main(int n=1)
{

int i;

cout<<endl<<n;

func[0]=&exit;
func[1]=&main;

i = ++n <= 10;

(func[i])(n);

}

This code prints numbers from 1 through 10.

Replace 10 with any positive number, and it would print the desired result.

Here is what u want Next Question Smile

Reverse a singly linked list recursively. The function prototype is node * reverse (node *) .

Hey guyz u can also post ur questions.So plz u also plz post some questions but plz one question at a time.

Thursday, October 18, 2007 9:04 PM

this code worked for me..

Friday, October 19, 2007 6:01 PM

Nice answer only u giving all answers Smile

.

U can also ask ur questions this thread is open for all.
And if you find my questions useful plz mark it

I will post next question tonight if no one else posts.

Saturday, October 20, 2007 10:18 AM

Thanx man!

Yes i'll be posting some questions in a few days from now. Just wait for some time.

Post your questions in the mean time.

And OTHERS can also post their questions.

We'll definitely try to solve them.

Saturday, October 20, 2007 1:08 PM

A new challenge

Display the non Fibonacci series

Ex- 4 6 7 9 10 11 12 ..........................

Sunday, October 21, 2007 9:17 AM

One way can be to print all numbers and keep checking for a number that it is in fibonacci series or not.

Any other idea so plz tell me i am in hostel i will also try some other if i get a pc. Smile

Till then here is next question:-

////////////////////////////////////////////////////////////////////////

Provide c++ code to complete this program

int** func1(int** arg1)

{

int** temp;

//allocate memory dynamically then copy arg1 to temp increment every element in temp by 5

// then print temp

//return temp

}

void main()

{

int** a;

// allocate memory dynamically then assign a 3x3 matrix in a

//print a

// call a and save result returned in a only then print a

//output of last two print statements should be same

//free the space of a

}

@jain

let me checkout...but u did so quick....

Saturday, October 27, 2007 8:23 AM

ya he is so quick.
I was also working on this qestion but its a long program and due to lack of PCin hostel couldn't coplete it Sad

And i will be waiting for your answer jain .

Sunday, October 28, 2007 7:18 AM

Tuesday, October 30, 2007 6:17 AM

still waiting for ur answer

Thursday, November 1, 2007 10:57 AM

very very good

Friday, November 2, 2007 7:12 AM

Common guyz can no one answer this question ??

Till then here is next question:-

////////////////////////////////////////////////////////////////////////

Provide c++ code to complete this program

int** func1(int** arg1)

{

int** temp;

//allocate memory dynamically then copy arg1 to temp increment every element in temp by 5

// then print temp

//return temp

}

void main()

{

int** a;

// allocate memory dynamically then assign a 3x3 matrix in a

//print a

// call a and save result returned in a only then print a

//output of last two print statements should be same

//free the space of a

}

//////////////////////////////////////////

if u can't reply i will post anser in nxt 48 hrs if ono one can answer.This was such a basic question.

Monday, November 5, 2007 4:50 PM

Here's the answer ---

Code Block

int** func1(int **arg1)
{
int **temp,i,j;

temp = new int*[3];
for(i=0;i<3;i++)
temp[i] = new int[3];

cout<<endl<<"Displaying <temp>... values copied to <temp> and incremented by <5>"<<endl;

for(i=0;i<3;i++)
{
  for(j=0;j<3;j++)
  {
   temp[i][j] = arg1[i][j];   // COPY "arg1" to "temp"
   temp[i][j] += 5;          // INCREMENT each element of "temp" by "5"
   cout<<" "<<temp[i][j];     // DISPLAY "temp"
  }
  cout<<endl;
}
return temp;
}

void main()
{
clrscr();
int **a;
int i,j;
a = new int*[3];
for(i=0;i<3;i++)
  a[i] = new int[3];
cout<<endl<<"Enter NINE values --- 3 by 3 matrix"<<endl;
for(i=0;i<3;i++)
{
  for(j=0;j<3;j++)
  {
   cin>>a[i][j];
  }
  cout<<endl;
}

cout<<endl<<"Displaying <a> before operation..."<<endl;

for(i=0;i<3;i++)
{
  for(j=0;j<3;j++)
  {
   cout<<" "<<a[i][j];
  }
  cout<<endl;
}

a=func1(a);

cout<<endl<<"Displaying <a> after operation... result stored in <a>"<<endl;

for(i=0;i<3;i++)
{
  for(j=0;j<3;j++)
  {
   cout<<" "<<a[i][j];
  }
  cout<<endl;
}

delete a; // free <a>
}

how 2 put integer value or any number into array....using c program.

eg...
input i = 123

output
a[0]=1
a[1]=2
a[2]=3

Predict the output of the following :

Code Block

#include<iostream.h>

void main()

{int a=10,b;

b=(a++,a++,a++);

cout<<a<<" "<<b;

}

Sunday, December 16, 2007 3:09 PM

output will be 13 12

Monday, December 17, 2007 7:07 AM

@ jaggi

can u explain why..???

Monday, December 17, 2007 3:12 PM

NO more ques ah??????????

Saturday, January 5, 2008 6:02 AM

Really happy about this forum.. Today only i got to know about this forum:

1. Write a pgm to delete a node from a single link list , without using starting node?
2. Reverse bits of short int ?

Thanks in advance.

third a is assigned to b before increment

Tuesday, October 14, 2008 11:06 PM

Here is another simple way. Dont pass any command line arguments.

Replece the 10 with any number.

#include <stdio.h>
#include <conio.h>

#define MAX 10

main(int argc,char *argv[])
{
   if (argc == MAX+1)
{
     getch();
     return 0;
}
printf("%d \n",argc);
main(++argc,NULL);
}

#include<iostream>

using namespace std;

void main()

{int a,b;

cin>>a>>b;

while(b--)

}
