What punctuation ends most lines of C and C plus plus code?
C programs are composed from data types and functions. Functions are composed from one or more statements. A statement is composed from one or more expressions terminated by a semi-colon. A semi-colon without an expression is itself a statement (an empty statement). Every C program must have at least one function, the global main function. This serves as the entry-point of the application. When we return from the main function, the program terminates normally. The C standard requires that the global main function return an integer to the execution environment, where the value 0 is conventionally used to indicate "no error". As such, the minimum C program is as follows: int main (void) { return 0; }
Is the colon a valid example of CSS syntax?
No, a single colon in itself is not a valid example of CSS syntax.
Why do you use semi colon in do while statement?
A semi-colon is used in a do while statement for the same reason that it is used in any other statement. The rules of C and C++, as well as Java, require that every statement be terminated with a semi-colon.
When no semicolon is used after printf statement what will be the output?
A semi-colon denotes the end of a statement. If you omit the semi-colon, the statement will extend into the next expression and this will result in a compiler error because a semi-colon will have been expected at the end of the first expression.
Does every line in C program end with a semicolon?
Yes, but it will be difficult, because you will need to explicitly declare any library functions and constants that you will need, and often there are many such declarations. If you are talking about a header file specific to your program, the answer is still yes; simply declare your functions and constants before you use them. This is often done in single file program that are provided on the Internet - the file will contain includes for "standard" headers, but none for specific program related headers - and the order of functions will simply be backwards, with main() at the end - or the function will be declared at the top, with main() immediately after the declarations.
