Thread: hexadecimal numbers

if() is NOT a function, it's a statement.

Code:

if(expression)
{
      statement1;
      statement1;
      '
      '
}

if(the the expression is true, then it goes into the braces, otherwise it jumps to the closing brace.

You can have if statement, nested if...else, but NOT only else

Code:

if(expression 1)
{
      statement1;
      statement2;
      '
      '
}
else if(expression 2)
{
      statement1;
      statement2;
      '
      '
} 
'
'
'
'
else
{
      statement1;
      statement2;
      '
      '
}

oh man!!!!!!!!!!!!!!!!!!!! finally... guys!!!!!! i completed the code.. thanks gaurav, that flag idea of urs saved my butt.... and ur if() STATEMENT is very clear now...


here's the code

Code:

#include<stdio.h>
#include<conio.h>
#include<math.h>
void low_up(char *);
void main()
{
	char ch[4];
	int temp[4],i,hex=0,dec=0;
	clrscr();
	printf("Enter a hexadecimal number");
	for(i=0;i<4;i++)
	{
		scanf("%c", &ch[i]);
	}
	for(i=0;i<4;i++)
	{
		if((ch[i]>='a' && ch[i]<='f')||(ch[i]>='A' && ch[i]<='F'))
		
			hex++;
		else
		
			dec++;
	}
	if(dec==4)

		printf("This is not a hexadecimal number");

	else
	{
		printf("This is a hexadecimal number");
		low_up(ch);
	}
	for(i=0;i<4;i++)
	printf("%c", ch[i]);

	getch();
}

void low_up(char *j)
{
	int k;
	for(k=0;k<4;k++)
	{
		if(*j>=97 && *j<=102)
			*j=*j - 32;
		else if(*j>=65 && *j<=70)
			*j=*j + 32;
		j++;
	}


}

Mostly I think it's your pigeon english that confusing people. It's so mangled up that it's amost impossible to read... like the crap grade school kids send on text messages. I don't know if English is your first language or not but, in any case, you really should make a sincere attempt at writing legibly...

yes i do tend to type like that when i'm in a hurry... but FYI english is my first language and i have no problems whatsoever writing or speaking english fluently... but i didn realise that there are slow(at mind) people here.. so i'm sorry next i will type out my questions properly so that slow people(like you, especially you) can understand well.

P.S.(stands for Post Script) : FYI stands for "For your information"

i would like to say something here, no one have problem with your english , the thing is your attitude.
Lots of people are here who wants to use their intelligence to help others. So I request you, don't disappoint them.
