错误: v. contents[30] 用于此函数中未初始化的功能
原标题:error: v.contents[30] is used uninitialized in this function

这是我的支架,

typedef struct _values {
int contents[MAX_CONTENTS];
    ... more ints;
} values;

在另一个函数中, 我初始化此特定的数组, 使用 :

int contents[MAX_CONTENTS] = {0};

for (i = 0; i < MAX_CONTENTS; i++) {
    v.contents[i] = contents[i];
}

在我的主体里,我有这个;

values v;
newValues (v);

每当我试图修改这样的主元素时, 我就会得到错误;

v.contents[30] = 3;

这是我唯一的错误,我做错什么了?

最佳回答

v (和 contents 内) 可能会被值传递。 将您函数的原型更改为 :

void newValues(values *v);

改变你如何称呼它到这个地步:

newValues(&v);

而不是:

v.contents[i] = /* ... */;

使用 :

v->contents[i] = /* ... */;
问题回答

你可能打算这样抄写:

for (i = 0; i < MAX_CONTENTS; i++) {
    v.contents[i] = contents[i];
}
