i didn't get u..

give me link to download Turbo C software, which works on windows8.

N Shiva 25-Jun-13 5:09am View

As my system is win8, I can't install any 'C' compiler. For this program I am using online compiler codepad.org

No, a problem on some coding site...just trying 2 solve.

N Shiva 18-Oct-12 10:50am View

I meant, I knew how to get product mathematically, If i wrote a function, How to return two no.s (imaginary & real) at a time ?

a simple way is wherever you want you can use this formula right...

(x + yi)(u + vi) = (xu – yv) + (xv + yu)i.

check this one aswell... somebody said some error in the above solution..
above code is incorrect. removind + and i from the scanf the code will work fine.
New and simple version for the above problem is
#include
int main()
{
int a,b,c,d,e,f;
printf("\nEnter the first complex number ");
scanf("%d %d",&a,&b);
printf("\nFirst number is ");
printf("%d + %di",a,b);
printf("\nEnter the first complex number ");
scanf("%d %d",&c,&d);
printf("\nSecond number is ");
printf("%d + %di",c,d);
e = a*c - b*d;
f = a*d + b*c;
printf("\nAfter multiplication ");
printf("%d+%di",e,f);
return 0;
}

ok...

N Shiva 17-Oct-12 12:11pm View

ok..thnx.. I will create a structure and i will write functions to add complex no.s (2 real numbers and 2 imaginary no.s) But how to get product ?

N Shiva 17-Oct-12 11:55am View

Assume if i have defined a structure named complex, which has two fields i mean 2 floats one is imaginary and another is real.... How addition & multiplication of these no.s will be simple ?

N Shiva 17-Oct-12 11:30am View

Is there any other way in 'C', except what I mentioned above.

N Shiva 14-Oct-12 11:42am View

See once.. I edited the question...

N Shiva 11-Oct-12 1:50am View

Thnk you.. but array c is also float array.

N Shiva 10-Oct-12 6:36am View

Thnx. I got it.
1. why these are wrong?
float a[r1][c1];
float b[r2][c2];

You said "These statements are evil wrong (at compile time r1, c1, .. values are indefinite)! "

2. I replaced if ( product(a,b,c) ) return -1; ...with... product(a,b,c). is there any mistake. i am getting correct result.

3. I donno why you changed definition of product function from float to integer.

N Shiva 10-Oct-12 6:20am View

The code you have given is ok. But
1. if ( product(a,b,c) ) return -1;
this means exactly?
2. How can I use this product function when I wanted to calculate 'Q' which is equal to x*y*z.

N Shiva 10-Oct-12 5:21am View

I defined functions like ... float product(float a[20][20],float b[20][20],float c[20][20])...
and called this function in main as product(a,b,c), (I declared array-'C' in main function)... then execution is as follows:

Enter no.of rows of first matrix: 2
Enter no.of columns of first matrix: 2
Enter no.of rows of second matrix: 2
Enter no.of columns of second matrix: 2
Enter the elements of first matrix: 1 2 3 4
Enter the elements of second matrix: 0 3 2 1

4.000000 5.000000
0.000000 -1.931809

But i shoud get
4 5
8 13

N Shiva 10-Oct-12 4:13am View

I tried this, i mean product(a,b,c)..and all.....but i am not getting any error, but iam getting wrong ans. I donno why?

N Shiva 9-Oct-12 12:44pm View

That was code in C language. May I knw what is wrong in it.

N Shiva 9-Oct-12 12:39pm View

My sole intention to write this function is, I use it in b/w my program related to Graph theory. where I may use product(product(x,y),z) to get x*y*z.

N Shiva 9-Oct-12 12:17pm View

When I declared array-C in main function and I passed it to product function{along with a & b }, I didn't get any error, but Iam getting wrong ans.

N Shiva 9-Oct-12 12:13pm View

Then how can I print this when I want to?

N Shiva 9-Oct-12 12:06pm View

Sorry, Iam not getting u.

N Shiva 9-Oct-12 11:47am View

How can I catch the result in that function. I mean c[i][j].
I just want to store that in array c.

N Shiva 9-Oct-12 11:35am View

Iam using array-c in main() even though it is not declared in main(). But even If I declare above main also Iam getting this error.

matr.c:5: error: variably modified ‘c’ at file scope

N Shiva 9-Oct-12 1:06am View

ok. Thnkyou.

N Shiva 8-Oct-12 12:15pm View

THNX. I got it... I have to use cc -lm while executing...

yes...iam trying. but didn't getting. Iam getting this error nw.

Sorry. I am unable to access that site from my campus.
Could you please tell me, what is the mistake.
