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.
// C program showing the header file including // standard input-output header file #include int main {// "printf()" belongs to stdio.h printf ("hello world"); return 0;} Output hello world. Example 2. In the below example, the #include directive allows us to use mathematical functions like sqrt for calculating the square root. C
If we use #include in your c program, it will include stdio.h file into our source program which has the information for all input, output related functions. Why int main()? As we discussed earlier, the main function is the starting point of program execution.
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 ...

Consider the following C program: #include<stdio.h> int main() { int i, j, k = 0; j ... The number of times printf statement is executed is _______.
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.
