C语言教学中强制类型转换运算运用探讨

Discussion on the Compulsory Type Conversion Operator in C Language Teaching

在C语言中有一个强制类型转换运算符,它为C语言中的数据类型转换带来很大的方便,它不仅可以在不同类型数据之间进行赋值,在运算中发挥强大的作用,还可以运用在其他方面产生特殊作用。通过程序例子讨论强制类型转换运算在函数调用时实参与形参类型如何保持统一,计算时如何保持结果的精度及指针类型转换等几方面的运用。

There is a compulsory type conversion operator in the C language. It is convenient for the conversion of data s types in the C language. It not only serves a great function on assigning values and operations between different data types, but also makes special effect in other aspects. Uses some programming examples to discuss actual parameters and formal parameters how to keep unification in function call, how to keep result precision and pointer type conversion.
