Compatibility D. correctness50 software products ability to perform the tasks required in the software requirements specifications accurately called the (software).Of A. the maintainability B. reusability C. Compatibility D. correctnessSecond, fill in the blank1. Expressions containing random function rand ()% 20 value of _ to _ interval.2 in the switch statement, each statement label the keyword case behind the expression contained must be integer _.If statement, each else keyword with it in front of the same level and closest to the _ keyword matching.4. As statement label use C + + reserved word case and default can only be used in the the _ statement defined body.Switch statement is executed during expression evaluation as a condition down from a matching label position from execution, to _ execute when the encounter next label position.6 If the head of the while loop is a while (i + + = 10), and the initial value of i is 0, and does not modify the value of i in the loop body, the body of the loop will be executed repeatedly _ times after the end of normal.Do loop tail as while (+ + i 10), and the initial value of i is 0, while in the body of the loop does not modify the value of i, the loop body is executed repeatedly _ _ times after the end of normal.When _ statement in the program execution will end the execution of the loop class statement or switch statement.9. _ Statement in the program execution will end where the loop statement first execution of the loop body.10. _ Statement in the program will end where during the execution of the function to return the position to call the function.11. In the _ function, the program execution will end the process of the implementation of the entire program, and return to the operating system under C + + integrated development window.12 elements of type int array a 10 of bytes of storage space occupied by _.13 element type of a two-dimensional array of double a 4 6 Total bytes of storage space occupied by _.14 elements of the two-dimensional array of type char a 10 30 Total occupied _ bytes of storage space.15 the store character a and the string a takes _ and _ bytes.16 empty string, the length of _, store it takes _ bytes.17 string a xy = n , length _.18 the length of the string a: xxk data _.19 for storing a length n string character array of length at least _.20 If a is an array of characters, from the keyboard to the array input a string expression _.21 If a character array to the screen output a string stored expression _.22 in a two-dimensional array of characters, a 10 20 is capable of storing _ strings, each string of length at most _.23. Initialized data of a two-dimensional array of characters A 123, 456, 789, A 1 elements corresponding string is _._ 24. Strlen (apple) value _ strcmp (a, A) has a value of.25 For want of a string aaa to assign values to the array of characters a, you need to perform the the _ function calls to achieve.26. Assumes two-dimensional array a 3 4 for initializing data for 3,5,6, 2,8, 7, A 1 1 and a 2 3 are initialized to _ and _.27 in the C + + language, a function by function head and _.28 overloaded a function: This function must be different from the other function of the same name in the number of parameters or parameter _.29 If a function is only allowed to function calls in the same file, it should be before the function definition with _C + + reserved words.30 double x = 100; is a global variable defined file F1.CPP in statement, if a function requires file F2.CPP in to access this x should file F2.CPP, add x statement statement for _.31 defining a function template to use a modifier is _.32 in the parameters of the function template the class modified parameter called _ parameters.33. If a function, directly or indirectly, to call itself, such a call is called _ call.34. Known the cubin int cubin (int n) return n * n * n; and double (double n) return n * n * n; are two instances of a function template, it is assumed that the type parameter T the definition of the function template is _.35 For without the return value of the function, defined functions use _ the modified function type.36 If a function is defined using _ modified, the function does not allow other file function call.37 If a function has multiple default parameters, the default parameters must all be in the _ part of the formal parameter list.38. Defined external variables without storage class specifier _, and use it to declare external variables.39. Call system function, first use the # include command contains the system function prototype statement where _.40. Scope of the function parameter is the function of _.41. C + + the pretreatment command provides macro definition commands, conditional compilation command and _.42. Program is compiled based on _ units.43. C + + the program runtime memory space can be divided into global data area, heap area, stack area and _.44 global variables and static local variable has the the static survival, stored in the memory of _ District.45. Partial survival of local variables, stored in the memory of _ District.46 if a two-dimensional array a m columns, set a 0 0 the first position in the array, is calculated to any element of a i j in the array position number formula _ .47 If the definition of double a 3 5;, a array subscript of BOC and column subscripts max were _ and _.48 If the definition of struct AA int a; char b; a double c; x; then x footprint size _ bytes.49 When defining a structure variable, the system assigned to the variable memory size is equal to each member of the memory size required _.50 a pointer to a
