Основы программирования в Linux полностью

               unqualified storage: array[0].data = "bill"

A read-only string literal is assigned to a non-observer reference. (Use -readonlytrans to inhibit warning)

debug0.c:8:18: Read-only string literal storage used as initial value for

               unqualified storage: array[1].data = "neil"

debug0.c:9:18: Read-only string literal storage used as initial value for

               unqualified storage: array[2].data = "john"

debug0.с:10:18: Read-only string literal storage used as initial value for

               unqualified storage: array[3].data = "rick"

debug0.c:11:18: Read-only string literal storage used as initial value for

               unqualified storage: array[4].data = "alex"

debug0.с:14:22: Old style function declaration

 Function definition is in old style syntax. Standard prototype syntax is

 preferred. (Use -oldstyle to inhibit warning)

debug0.с: (in function sort)

debug0.c:20:31: Variable s used before definition

 An rvalue is used that may not be initialized to a value on some execution

 path. (Use -usedef to inhibit warning)

debug0.с:20:23: Left operand of & is not unsigned value (boolean):

               i < n & s != 0

 An operand to a bitwise operator is not an unsigned values. This may have

 unexpected results depending on the signed representations. (Use

 -bitwisesigned to inhibit warning).

debug0.c:20:23: Test expression for for not boolean, type unsigned int:

               i < n & s != 0

 Test expression type is not boolean or int. (Use -predboolint to inhibit

 warning);

debug0.с:25:41: Undocumented modification of a[]: a[j] = a[j + 1]

 An externally-visible object is modified by a function with no /*@modifies@*/

 comment. The /*@modifies ... @*/ control comment can be used to give a

 modifies list for an unspecified function. (Use -modnomods to inhibit

 warning)

debug0.c:26:41: Undocumented modification of a[]: a[j + 1] = t

debug0.c:20:23: Operands of & are non-integer (boolean) (in post loop test):

               i < n & s != 0

 A primitive operation does not type check strictly. (Use -strictops to

 inhibit warning)

debug0.с:32:14: Path with no return in function declared to return int

 There is a path through a function declared to return a value on which there

 is no return statement. This means the execution may fall through without

 returning a meaningful result to the caller. (Use -noret to inhibit

 warning)

debug0.с:34:13: Function main declared without parameter list

 A function declaration does not have a parameter list. (Use -noparams

 to inhibit warning)

debug0.с: (in function main)

debug0.с:36:22: Undocumented use of global array
