Thread: mpz_mul(r, b, x);

Hi all,

I have this code:

Code:

#include        <stdio.h>
#include        <gmp.h>


int main (int argc, char* argv[])
{
        printf("Here!");
        mpz_t   b, x, r;


        if (argc != 2) {
                printf("Help");
                return 2;
        }

        mpz_init(b);
        mpz_init(x);
        mpz_init(r);

        gmp_sscanf(argv[1], "%Zd", b);
        gmp_sscanf(argv[2], "%Zd", x);

        printf("X = %Zd Y = %Zd",b,x);
        mpz_mul(r, b, x);

        gmp_printf("%Zd * %Zd = \n", b, x, r);
        printf("Entered");

        return 0;
}

The mutliplication is not working. Actually, it prints only the first print
statement : Here!.

Any suggestions?

Why isn't this
gmp_printf("X = %Zd Y = %Zd",b,x);

Did you run the program with two command line arguments?
argc would be 3 by the way.

Yeah, I run it with 2 args:

$ ./mul.exe 2 3

As I changed the printf() to gmp_printf(), but with no changes

Oh, I got where is the mistake.
Thanks Salem.
