arrays - C 中权重 [a]= 数据上的段错误；

Question

fscanf(ifile, "%c", &jnk);
/* If there's a height, this will be a ". if not, it'll be a ,*/
if ((jnk = '\"') || (jnk != ',')) {
    printf("%c", jnk);
    while(fscanf(ifile, "%c", &data) && data != ',' && data != '\"' && data != '\'') {
        printf(" %c ", data);
        weight[a]= data;
        a++;
    }
    weight[a] = '\0';
    player[n].weight=atof(weight);
    printf("%.0f ", player[n].weight);
} else if(data == ' ' || data == ',') {
    player[n].weight= 0;
    printf("%.0f ", player[n].weight);
}

GDB 告诉我将数据存储到权重中会导致段错误。谁能告诉我为什么？

问题出在这里:

我希望您将 " 和 , 分配给 a。当您使用 weight[a] 时，您会收到错误，因为 ASCII获取字符的值，该值可能超出您声明的数组大小的范围
