What are octal literals in C++?

Can you explain what octal literals are in C++?

Sure! Octal literals in C++ are numbers represented in base 8, using digits from 0 to 7.

How do I write an octal literal in my code?

You can write an octal literal by prefixing the number with a '0'. For example, '012' represents the octal number 12.

What happens if I use a digit greater than 7?

If you use a digit greater than 7, it will result in a compilation error since octal only allows digits 0-7.

Can you give me an example of using octal literals in a program?

Certainly! Here's a simple example:

#include <iostream>
int main() {
    int octalNum = 012; // This is octal for 10 in decimal
    std::cout << octalNum;
    return 0;
}
