Computer - Chap 5 -Introduction to 'C' Language

1.     Errors are mistakes in program, which     are traced by the compiler.

Que 13.Explain errors of C programs in detail.

Ans. Errors are mistakes in program, which are traced by the compiler while compilation. A program can only execute when all the errors are corrected.

 Types of errors:

1)                Logical errors – occur when the result we get is not correct because of the incorrect code logic.

2)                Syntax : occur when the grammar of the C language is not used properly.

For ex

1.     Typing Printf or print instead of  printf.

2.     Forgetting a semicolon (;) at the end of an executable C statement.

3.     Mismatch of parenthesis.

1.  Typing Printf or print instead of printf.

2.  Forgetting a semicolon (;) at the end of an executable C statement.

3.  Mismatch of paranthesis.

Ans. Format Specifiers are % sing followed by a letter which actually prints the value of the variable. Following are the list of format specifiers used in C to print the value of variables of different types.

%c	Character format Specifiers
%d	Signed Integer format Specifiers
%f	Floating point format Specifiers
%lf	Floating point format Specifiers
%s	String format Specifiers
%u	Unsigned Integer format Specifiers
%n	Prints nothing
%%	Prints % character
