C如何将.txt文件的内容放入二维数组

#include <stdio.h>

#define MAX_ROWS 100
#define MAX_COLS 100

int main() {
    FILE *file;
    char filename[] = "example.txt";
    char buffer[100];
    int array[MAX_ROWS][MAX_COLS];
    int row = 0, col = 0;

    file = fopen(filename, "r");
    if (file == NULL) {
        printf("Failed to open the file.\n");
        return 1;
    }

    while (fgets(buffer, sizeof(buffer), file)) {
        col = 0;
        char *token = strtok(buffer, " ");
        while (token != NULL) {
            sscanf(token, "%d", &array[row][col]);
            col++;
            token = strtok(NULL, " ");
        }
        row++;
    }

    fclose(file);

    // 输出二维数组中的数据
    for (int i = 0; i < row; i++) {
        for (int j = 0; j < col; j++) {
            printf("%d ", array[i][j]);
        }
        printf("\n");
    }

    return 0;
}
