Process returned -1073741819 (0xC0000005) (in a simple matrix)

I'm new here and this is my first question regarding a small C program. I've been learning this language recently and I don't know how to move yet. Could someone help me out? Entering numbers in an array from time to time gives me this error: Process returned -1073741819 (0xC0000005). Thank you in advance.

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

#define R 5
#define C 5
int main(int argc,char argv[]){

    int A[R][C];
    int i,j;
    for(i=0;i<R;i++){
        for(j=0;j<C;j++){
            printf("Numero [%d][%d]: ",i,j);
            scanf("%d",A[i][j]);
            printf("%d....%d",i,j);
        }
    }

    for(i=0;i<R;i++){
        for(j=0;j<C;j++){
            printf("%d",A[R][C]);
        }
        printf("\n");
    }
    return 0;

}
