End-of-line Comment: begins with // and lasts till the end of the current line.

Multi-line Comment: begins with a /* and ends with a */, and can span several lines.

Comments are not programming statements and are ignored by the compiler, but they VERY IMPORTANT for providing documentation and explanation for others to understand your program (and also for yourself three days later). Printf('The absolute difference is %d. ', absDiff) Ĭomments are used to document and explain your codes and program logic. Printf('The sum of even numbers is %d. ', sumEven) Printf('The sum of odd numbers is %d. ', sumOdd) Scanf('%d', &upperbound) // Use %d to read an int // Use a while-loop to repeatedly add 1, 2, 3., to the upperbound Int absDiff // The absolute difference between the two sums // Prompt user for an upperbound Int upperbound // Sum from 1 to this upperbound Int sumEven = 0 // For accumulating even numbers, init to 0 Int sumOdd = 0 // For accumulating odd numbers, init to 0

* Sum the odd and even numbers, respectively, from 1 to a given upperbound. Read ' Introduction to Programming in C for Novices and First-time Programmers' if you need help in understanding this program. C')īelow is a simple C program that illustrates the important programming constructs ( sequential flow, while-loop, and if-else) and input/output. K&R C: Pre-standardized C, based on Brian Kernighan and Dennis Ritchie (K&R) 'The C Programming Language' 1978 book.Otherwise, read ' Introduction to Programming in C for Novices and First-time Programmers'. I assume that you could write some simple programs.

This chapter explains the features, technical details and syntaxes of the C programming language.
