Thread: any one plz help me

hi friends em new here my first day first post
friends any one of you plz tell me long hand int calculations project its urgent coz i have to present it 26th of this month.

Please be more specific!

uuuuuuuuuuuuufffffffffff plz any one of u help me i have30 assignments of c as well n a project of communication skills and a n assigment of globalization and and and.......... and examz starts from 26th of this month i m too much bz but it doesnot matter how much i bz actually i dont how to solve it

So what's the problem? Specifically . . . ?

Show us some code and we'll help you solve the problems. Just paste them within [code][/code] tags

Code:

#define MAXDIGITS 100;
main()
type struct{
                  char digit[MAXDIGITS]
int signbit,
int last digit,
}big num;
digit m1,m2,m3;

***************************************
ch_to_bignum(char*s,bignum*n)
{
int i;
if(s[0]!='-')
{
n->signbit='PLUS'
i=0;}
else
{i=1;
n->signbit='MINUS'
}
strcpy(n->digits,&s[i])
n->lastdigit=strlen(n->digits)
}

there are too much errors in this code actually this was given by my teacher and i copy it from white board

hey this is not the actuall code my sir gives my this i have to solve long long integres calculation e.d 10000000000000000000000000000000000000000000000000 000000000000000+1000000000000000000000000000000000 000000000000000000000000000000000000000000000 like this and subtraction and division as well

Drop the ; at the end of this line

You should be specific about what the function returns.
main for instance always returns int. Your other function should probably return void

> char digit[MAXDIGITS]
Each member of your struct should finish with a ;
Like
char digit[MAXDIGITS];

> int last digit,
C doesn't allow spaces in variable names. So
int lastdigit;
int lastDigit;
int last_digit;
pick a style you like.

> n->signbit='PLUS'
Maybe just
n->signbit='+';
Again, don't forget those ;

thx but in last line i have to print PLUS not +

Here's the function fixed:

Code:

typedef struct
{
	char digit[100];
	int signbit;
	int last_digit;
} big_num;

void ch_to_bignum( char*s,big_num*n )
{
	int i;
	if(s[0]!='-')
	{
		n->signbit='+';
		i=0;
	}
	else
	{
		i=1;
		n->signbit='-';
	}
	strcpy(n->digit,&s[i]);
	n->last_digit=strlen(n->digit);
}

There were tones of mistakes! From misnaming variables, missing ;'s, spaces in variables not to mention the indenting!

Use it like this:

Code:

int main( void )
{
	big_num m1;
	char *test_ch = "242";

	ch_to_bignum( test_ch, &m1 );

	cout<< m1.digit << '\n'
		<< m1.last_digit << '\n'
		<< m1.signbit << '\n';

	return 0;
}

thx buddy but this will not only solve my prob me have to solve long long int calculations

ya my teacher wrote that code but he was just giving us hints
