将float分配给int变量不会引起任何警告 [英] assigning float into int variable causes no warning

问题描述

因此，给出以下代码:

int main(void) {
  int i;
  i = 12.1234;
  i++;
  return 0;
}

我编译了代码，我期望并希望编译器给我一个警告，但事实并非如此.我的编译器配置错误吗?有没有办法让我的编译器发出警告?

I compiled the code and I expected and wanted the compiler to give me a warning, but it didn't. Is my compiler configured wrong? Is there a way to make my compiler give warning?

这就是我用的

cc -Wall test.c

cc -Wall test.c

推荐答案

浮点值可以分配给一个整数变量，但是当编译器强制将浮点值分配为整数.

A float value can be assigned to an integer variable but an implicit conversion occurs when compiler forces a float value to be assigned as an integer.

在将浮点值分配给整数后，浮点值中小数点后的数字会丢失.

The digits after the decimal notation in the float value get lost after assigning a float to an integer.
