Int x=3; //x=3
if(x==2); //x=3
x=0; //x=0
if(x==3) //x=0
x++; //x=0
else x += 2; //x=2

A goto statement implements a local jump of program execution, and the longjmp() and setjmp() functions implement a nonlocal, or far, jump of program execution. Generally, a jump in execution of any kind should be avoided because it is not considered good programming practice to use such statements as goto and longjmp in your program. A goto statement simply bypasses code in your program and jumps...

A global variable that must be accessed from more than one file can and should be declared in a header file. In addition, such a variable must be defined in one source file. Variables should not be defined in header files, because the header file can be included in multiple source files, which would cause multiple definitions of the variable. The ANSI C standard will allow multiple external definitions,...

Unfortunately, the only way to search a linked list is with a linear search, because the only way a linked list�s members can be accessed is sequentially. Sometimes it is quicker to take the data from a linked list and store it in a different data structure so that searches can be more efficient. �

There are times when it�s necessary to have a pointer that doesn�t point to anything. The macro NULL, defined in <stddef.h>, has a value that�s guaranteed to be different from any valid pointer.
