Thread: Create two arrays from command line and work on them

Hello,
I'm trying to make it possible such that when I run from the commadn line the following :
./program 1 2 3 | 3 4 5
it will create two arrays, A and A1 and process them as per the match function (which I did test to work). So I only need help with the Array extractor methods and the main. Awaiting your kind suggestions.

Code:

#include <stdio.h>
#include <stdlib.h>
#include <string.h>

void match(int A1[], int A2[]){
    int n1 = sizeof(A1);
    int n2 = sizeof(A2);
    int i,m,a1k,a2i,l,r,a1m;//global variables
    int a10=A1[0];

    for (i=0; i<n2; i++){//scan all elements of A2
        a2i = A2[i];//for efficiency
        if (a10 == a2i || A1[i]==a2i) printf("%d\t",a10);//special cases: print element
        else{ //when special case not true
            r = n1-1;
            l = 0;
            if (a2i >= a1k){
                if (a1k == a2i)
                    printf("%d\t",a1k); //print the element
                else{
                    while(r>=l){//since A1 is sorted
                        m = (l+r)/2;
                        if (a2i == (a1m = A1[m])){ //if element is found
                            printf("%d\t",a1m); //print the element
                            break;}
                        else{
                            if (a1m > a2i) r = m-1;
                            else l = m+1;
                        }
                    }
                }
            }
        }
    }
}
int * arrayExtractor(const char * argv[], char sep[]){
    int n,i=1;
    while (strcmp(argv[i], sep) != 0) {n++;}
    static int * A;
    for (i=1; i<n; i++){A[i] = atoi(argv[i]);}
    return A;
}

    int i=2;
    while (argv[i] !=  sep) i++;
    static int * A1;
    for (i=2; argv[i] != '\0'; i++){A1[i] = atoi(argv[i]);}
    return A1;

int main(int argc, const char * argv[]){
