I was using GMP library for build an binary arithmetic, but for multiplication, I want to return a result a multiplication without carry..
How can I implementing it?
nb: the code below give a result of multiplication with carry

Code:

void multi(){
     int m_bit;int m_bit2;
     char *op1;
     char *op2;     
     char *final;
     
     mpz_t hasil_acak,hasil_acak2,hasil_pangkat,hasil_exor_temp,hasil_multi,hasil_multi_temp,hasil_exor_temp0;

i want to representation the large random bit to operate the arithmetic, like this

example
input n=10, then
10 random bit has create
A[]=[1011011100]
B[]=[0010010011]

i want to divide the array to any part like
A[]=[[10110],[11100]]
B[]=[[00100],[10011]]
_______________ ______xor (per block)
B[]=[[10010],[01111]]

how can i implementing it, using the...

helo, i wanna ask a basic question in my C program below

Code:

#include<stdio.h>

unsigned m,n;
unsigned a[100];
unsigned b[100];

c=a; m>=n; //error in this line, why??
for (int i=0; i<n; i++){
    c[i]=c[i]^b[i]
    }
return c;

error msg:
[warning]initialization makes integer from pointer without a ca...
