It should be #include .. The problem is that <> is replaces eith <> and it isn't replaced back. < is the HTML escape of < and > is the HTML escape of >. In order to prevent XSS, it may got replaced one time too much. E.g. the author wanted to use the HTML escape but the XSS protection escaped the escape and your browser undid the escape only once.

Question 1 c #include int main() { printf("%p", main); getchar(); return 0; } Output: Address of function main. Explanation: Name of the function is actually a pointer variable to the function and prints the address of the function.
All valid C programs must contain the main() function. The code execution begins from the start of the main() function. The printf() is a library function to send formatted output to the screen. The function prints the string inside quotations. To use printf() in our program, we need to include stdio.h header file using the #include
有人问：C语言为什么只需要include<stdio.h>就能使用里面声明的函数?这是一个看起来非常简单的问题，但是很多初学者，甚至学了很久的人都可能没有搞明白。为什么包含即可用？ 要明白包含即可用的原因，就必须讲到C语言代码是如何变成可执行文件的了，这里可以参考《hello程序是如何变成可 ...
🙋 Introduction. The header file in C is one of the most commonly used and essential libraries. It provides functionalities for input and output operations, making it a crucial part of any C programmer's toolkit. This guide will give you an in-depth look at what offers, its key functions, and how to use them effectively.. 🎯 Purpose of
2.2 Include Operation ¶. The '#include' directive works by directing the C preprocessor to scan the specified file as input before continuing with the rest of the current file.The output from the preprocessor contains the output already generated, followed by the output resulting from the included file, followed by the output that comes from the text after the '#include' directive.
The macro function CUBE(x) (x*x*x) calculates the cubic value of given number(Eg: 10 3.). Step 1: int a, b=3; The variable a and b are declared as an integer type and varaible b id initialized to 3.. Step 2: a = CUBE(b++); becomes => a = b++ * b++ * b++; => a = 3 * 3 * 3; Here we are using post-increement operator, so the 3 is not incremented in this statement.
It does not work. Try replacing "int *p;" with "int *p = NULL;" and it will try to dereference a null pointer. This is because fun() makes a copy of the pointer, so when malloc() is called, it is setting the copied pointer to the memory location, not p. p is pointing to random memory before and after the call to fun(), and when you dereference it, it will crash.
