Just Remember All this .
Its helps in C program .Basic of C programming .#- Every C program requires a main () function (Use of more than one main () is illegal ). The place main is where the program execution begins.
- The execution of a function begins at the opening brace of the function and ends at the corresporiding closing brace .
- C programs are written in lowercase latter . However , uppercase latter are used for symbolic names and output strings .
- All the words in a program line must be separated form each other by at least one space, or a tab , or a punctuation mark .
- Every program statement in a C language must end with a semicolon.
- All variables must be declared for their types before they are used in the program .
- We must make sure to include header files using #include directive when the program refers top special names and functions that it dose not define .
- Compiler directives such as define and include are special instructions to the compiler to helps it compile a program .They do not end a semicolon .
- The sing # of compiler directives must appear in the fast column of the line .
- When braces are used to group statement ,make sure the opening brace has a corresponding closing brace.
- C is a free-form language and therefore a proper form if indentation pf various sections would improve legibility of the program .
- A comment can be inserted almost anywhere a space can appear ,use of appropriate comments in proper place increases readability and understand ability of the program and helps users in debugging and testing . Remember to match the symbols /* and * appropriately .
