In this paper, we analyze the attention points of automatic implicit conversion and type casting in C language through a C program instance, as follows:
First look at a C program:
#include
#include
#include
double proc (int q) {
int
The basic elements of the Operator programming language, which makes our code more concise and straightforward. However, in order to solve the problem of different types of operands, we have introduced the concept of forced conversion. Let's look at
