Programming Rules

-
A programmer while writing a program should follow following rules. Every program should have main() function. C statements should be terminated by a semi-colon (;). At some place, a comma operator is permitted. If only a semi-colon is placed it is treated as a statement. For example:-                          while(condition)                          ; The above statement generates infinite loop. Without semi-colon the loop will not execute. An unessential semicolon if placed by the programmer is treated as an empty statement. All statements should be written in lowercase letters. Generally, uppercase letter are used only for symbolic constants. Blank space my be inserted between the words. This leads to improvement in the read-ability of the statements. However this is not applicable while declaring a variable, keyword, constant and function. It is ...
