The test expression done on exact statement. The good habit of using test expression on exact or fulfill statement. So do not use floating point numbers for checking for equality in the test expression.

Missing the inclusion of appropriate header file in c program will generate an error. Such a program may compile but the linker will given an error message as it will not be able to find the functions used in the program.

Semoclone ( ; ) is one of the best sensitive symbols in programming. Placing a semicolon ( ; ) after the WHILE or FOR loop is not a syntax error. So it will not be reported by the compiler. However, it is considered to be a logical error as it change

Specifier is a typedef-name and a very sensitive in C programming. Using an incorrect specifier for the data type being read or written will generate a run time error.

When you are using SWITCH case, it is important to keep in mind that the inclusion of DEFAULT LABEL. This will inform you whether you are executing your program in right or wrong way. So, it is always recommended to use DEFAULT LABEL in the SWITCH st
