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.

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

Not putting // before the start of single statement comment is a compiler error. Not putting the */ after the termination of block comment is a compiler error.

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.

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

Enter any integer number: 10

The summation of each digits of 10 is: 1

The summation of each digits of 10 is: 1
