Try this:

#include <stdio.h>
main()
{
	int	row, col, t, i;
	int	tab=40;
	for(row = 1; row <= 7; row++)
	{
		for (t = 1; t <= tab; t++) printf(" ");
		/* number if blank spaces from left edge of the screen */
		for(col = 1;col <= row; col++)
			printf("%d ",row);
		printf("\n");
		tab--;
	}
return 0;
}

Re: Post ur C/C++ Programs Here

do u know wht's the output of following prog


#include<stdio.h>
#include<conio.h>
void main()
{
int c;
c=printf("abc");
printf("\n%d",c);
getch();
}
Don't run it. Just guess it's output . & why?

    int    row, col, t, i;
    int    tab=40;
    for(row = 1; row <= 7; row++)
    {
        for (t = 1; t <= tab; t++) printf(" ");
        /* number if blank spaces from left edge of the screen */
        for(col = 1;col <= row; col++)
            printf("%d ",row);
        printf("\n");
        tab--;
    }
return 0;
}

He needed just 1s and in odd quantities only. Good write up though

Re: Post ur C/C++ Programs Here

what does printf return by the way? a return value or some pointer? It would take a minute to google that but I guess that would be cheating.

I think it returns an int. I've seen int in its prototype for sure. But I got no clue what the output of Projjwal's program's gotta be.

Re: Post ur C/C++ Programs Here

hint:





try it bro....u r partially correct ..It's the value which printf return..But wht is that value.? I give up the ans is
abc
3

Re: Post ur C/C++ Programs Here

Honestly Speaking this is going to be my fevorite thread ever on Digit forum...
BookMarked...
[Its very usefull for a BCA 3rd Sem student of a small town and thats me.. ]

OK, let me post my Today's Homework here..hehe...

Write a C Program to sort numbers of an Array using Bubble Sort Method.

#include <stdio.h>
#define MAX 10
void swap(int *x,int *y)
{
   int temp;
   temp = *x;
   *x = *y;
   *y = temp;
}
void bsort(int list[], int n)
{
   int i,j;
   for(i=0;i<(n-1);i++)
      for(j=0;j<(n-(i+1));j++)
             if(list[j] > list[j+1])
                    swap(&list[j],&list[j+1]);
}
void readlist(int list[],int n)
{
   int i;
   printf("Enter the elements\n");
   for(i=0;i<n;i++)
       scanf("%d",&list[i]);
}

void printlist(int list[],int n)
{
   int i;
   printf("The elements of the list are: \n");
   for(i=0;i<n;i++)
      printf("%d\t",list[i]);
}

void main()
{
   int list[MAX], n;
   printf("Enter the number of elements in the list max = 10\n");
   scanf("%d",&n);
   readlist(list,n);
   printf("The list before sorting is:\n");
   printlist(list,n);
   bsort(list,n);
   printf("The list after sorting is:\n");
   printlist(list,n);
}

^ theres nothing in Hint

There IS..
Just Highlight the post.

 

[Projjwal]

Re: Post ur C/C++ Programs Here

yea just highlight my previous post or just press "ctrl+ A ".Actually printf is a function with return type integer .Just open stdio.h file from include directory frm there u will got that. And it returns the length of string which it print.so as a result
c=printf("abc")
means printf return value 3 Which saved in C integer variable thats all.

Cool Projjwal, thanks Quiz Master

Re: Post ur C/C++ Programs Here

So,everybody of the forum know swapping using 3rd variable & without 3rd variable .now write a swapping program in c without 3rd variable & de vital point is use one line function only .
means
b=a+b;
a=b-a;
b=b-a;
---------------de above program has 3 functional lines now write it in one functional line.

Re: Post ur C/C++ Programs Here

^^eh..how do we do that?

 

[aditya.shevade]

Re: Post ur C/C++ Programs Here

Easy. Check this out.

#include<iostream>

using namespace std;

main()
{
	int a, b;
	
	cout << "Enter A and B" << endl;
	cout << "a = ";
	cin >> a;
	cout << endl << "b = ";	
	cin >> b;
	
	a = ((b - a) + (b = a));
	
	cout << endl << "a = " << a << endl;
	cout << "b = " << b;
	
	return 0;
	
}

EDIT : Output :-

EXECUTING:
/home/aditya/test 
----------------------------------------------
Enter A and B
a = 12

b = 23

a = 23
b = 12
----------------------------------------------
Program exited successfully with errcode (0)
Press the Enter key to close this terminal ...

Dev C++ too? Doesn't the output remain in the console box? Anyway for TC++ you need to call getch(); just before the end of the main function ( Before } ) but I guess you'd definitely know that

You mean to say that you get the output but not the final result or does it end abruptly in middle (Segmentation fault?)
