As mentioned earlier, a computer program is a collection of instructions or statements.A C program usually consists of multiple statements.Each statement is composed of one or more of the three given below:CommentsWhitespace charactersTokensIn a computer program, a comment is used to mark a section of code as non-executable.Comments are mainly used for two purposes:To mark a section of executable code as non-executable, so that the compiler ignores it during compilation.To provide remarks or an explanation on the working of the given section of code in plain English, so that a fellow programmer can read and understand the code.In C, there are two types of comments:end-of-line comment : It starts with //. The content that follows the // and continues till the end of that line is a comment. It is also called as single-line comment.traditional comment : It starts with /* and ends with */. The content between /* and */ is the comment. It is also called as multi-line comment.The code given below shows the two types of comments:/* C programming language was developed by Dennis Ritchie. This is called a header comment which is used to describe what this program would do. As you can notice the comment is spanning across multiple lines.*/#include <stdio.h>void main() { int num1 = 10, num2 = 20; printf("sum of two numbers = %d", num1 + num2);}//end of the main() function - this is an example of a end-of-line commentRead the code given below to understand the different types of comments. Retype in the space provided.Given below are 3 important points regarding comments:There should not be any space between the two forward slashes in //, i.e., / / is incorrect. Similarly, there should not be any space between the slash and star characters in /* and */, i.e., / * and * / are incorrect.Comments do not nest, i.e., /* and */ comment has no special meaning inside a // comment.Similarly, a // comment has no special meaning inside a /* comment.One should not write comments inside character literals (i.e., characters enclosed between single-quotes). Comments inside String literals (i.e., text enclosed between double-quotes) are treated as part of the String's content.Sample Test CasesTest Case 1:Expected Output:
