NOI OJ 1.2 10：Hello, World! Size of C language

describe

Remember in the last chapter , We have output “Hello, World!” Do you ？

Although it is not the basic data type involved in this chapter , But we can also use sizeof Function to get the size of the space it occupies .

Please program to find its size , See if it's the same as you think ？

Input

nothing .

Output

An integer , namely “Hello, World!” Size .

Let's start with an obvious error demonstration （ Don't spray ）

#include<stdio.h>;
int main(){
char a=" Hello, World!";
printf("%d",sizeof(a));
return 0;
}

This is the error code ！！！！！！！！！！！

char Is used to store character data , example ：'x' and   '*'

Here, " Hello, World!" Obviously beyond this range , So we don't have to use char To declare , We can output directly sizeof(" Hello, World!"), The resulting value is an integer , You can export it directly .

Correct code ：

#include<stdio.h>
int main(){
printf("%d",sizeof("Hello, World!"));
return 0;
}
