如何将二维数组的字符串拆分为一维integer

Question

I tried the code below, but the problem is that, I cannot get the last array in the end, any suggestion?

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

int main() {
    char *token;
    char str[20] = "{{0,1},{1,1},{45,56},{0,1}}";
    int* arr = malloc(sizeof(int) * 8);
    
    token = strtok(str, "},{");
    int count = 0;
    while(token != NULL){
        printf( " %s\n", token);
        arr[count] = atoi(token);
        token = strtok(NULL, "},{");
        count ++;
    }
    
    for (int i=0; i<8; i++){
        printf("%d\t",arr[i]);
    }
   
   return(0);
    
}

Answer 1

for example

int a[4][2];

sscanf("{{0,1},{1,1},{45,56},{0,1}}", "{{%d,%d},{%d,%d},{%d,%d},{%d,%d}}", 
        &a[0][0], &a[0][1], 
        &a[1][0], &a[1][1], 
        &a[2][0], &a[2][1], 
        &a[3][0], &a[3][1]);
