Which free C++ compiler is the best ?

The current best free c++ compiler would be MinGW compiler. You can get it along with Dev C++ by Bloodshed soft editor, which is free too.
But I use MS VC++ or TC++ depending upon the need. MS VC++ can do C++ very well, but for dos graphics programming I use TC++.

c programming

hey guys, i have problem with "c" progmming. the problem is- enter any 4 digit no. and display that no. in words. ex- 1234. result- one two three four.

plz hep me , it's urgent. :roll: :roll: :roll: :roll: :roll: :roll: :roll: :roll:

comm, if u have a question not related to this post, then post it as a new thread.
BTW, I guess you can do it by doing a itoa() on the number variable to get a char array of the numbers. Loop through this array and with a if...then construct, you can output the desired string.

 

[himtuna]

In c++ (don't know about c )you first extract all the digits then use switch case to get the desired output.
Extract 4digits like this
int a,b,c,d,n;
cin>>n;
a=n/1000;
b=(n%1000)/100;
c=(n%100)/10;
d=n%10;
switch(a)
case 1: cout<<"one";
...
....do it for b,c,d.

do u want it to read "one two three four" or "one thousand two hundred and thirty four". If it is the first then it is very easy.

 

[himtuna]

Then also it is easy
Like for first switch(a)
case1:
cout<<One thousand;
and for second switch(b)
case n:
cout<< n hundred;
since there are only four digits specified.

It is not easy in that case. Also when extracting numbers, numbers can be extracted only from right to left (using the mod % operatror). Try ur logic wth 1234. In ur logic u need to extract all numbers first and should be inserted into an array. One thosand (ok) two hundred (ok), three (what now? you have to check it in detail here). Ok it is not complicated. but require some lines of codes.

Here is my program which can read up to a maximum long int size or a 32 bit number in DOS platform.

//program to accept amount and to print it in wor
#include<stdio.h>
#include<conio.h>
#include<values.h>
void printsingles(int);
void printtenths(int);
void printthousands(int);
void printlacks(int);

int main()
{
	long int num,left;
	int tens,hundreds,thousands;
	clrscr();
	printf("Enter an Integer Number [Maximum %ld ] ",MAXLONG);
	scanf("%ld",&num);
	if(num<0) //if negative
	{
		printf("Minus");
		left=num* (-1); //convert into +ve
	}
	else
		left=num;
	do
	{
		if(left<20)
		{
			printsingles(left);
			left=0;
		}
		else if(left<100)
		{

			left-=(thousands*1000);
			if(left>0) printf(" and");
		}
		else if (left<100000L)

			printf(" Thousand");

			left-=(long)(lacks*100000L);
