ZZULIOJ 1000: Get into C language from today
topic description
"C language" is a shining name in programming languages. Everyone who studies computers and related majors will pay attention to it first when learning programming languages. C language is a widely used computer programming language developed at Bell Labs in the early 1970s. It has dominated the entire software industry for decades since its birth, and is known as the king of programming languages. Therefore, most universities at home and abroad will choose C language as the introductory language for learning programming, although it is not the most friendly and easy to learn for beginners.
Where is the difficulty of C language? The difficulty lies not in grammar, but in computational thinking. The cultivation of thinking requires a lot of programming practice. Therefore, the C language is not for listening and watching, but for hands-on and brain training. Think about the time and money you have spent on cultivating mathematical thinking from childhood to adulthood. In the information age, if you choose an IT-related major, it is worthwhile to put in as much effort to cultivate computational thinking. Come on, boy!
Please submit a program that outputs a statement: "Start learning C language today". (It means that you have to invest in it from today)

ZZULIOJ 1003: Four Arithmetic Operations on Two Integers
topic description
Input two integers num1 and num2, please design a program to calculate and output their sum, difference, product, integer quotient and remainder.
enter
The input is only two positive integers num1 and num2.
output
The output occupies one line, including the sum, difference, product, quotient and remainder of two numbers, and the data are separated by a space.

ZZULIOJ 1004: Digit Separation for Three-Digit Numbers
topic description
Input an arbitrary three-digit positive integer from the keyboard, and find the digits in the ones, tens and hundreds respectively.
enter
Enter any three-digit positive integer.
output
Output the digits of ones, tens, and hundreds in sequence. Separated by spaces, but there is no space after the last data, and the line will be broken directly.

ZZULIOJ 1005: integer powers
topic description
Input 3 integers and output their powers of 1, 2 and 3.
enter
Enter 3 integers, separated by spaces.
output
Output 3 lines with 3 integers in each line, which are their 1st power, 2nd power and 3rd power respectively. Each integer occupies 9 columns, and less than 9 columns are left-aligned.
