16 When calling a function, if the argument is an array name, then (b) is passed to the function.

The length of the array a The first address of the array b.

The address of each element in the c array The value of each element in the d array.

17 According to the following definition, the statement that can output the character 'a' is (b).

struct person

char name[10];

int age;

class[10]=;

a．printf(“%c”,class[3].name[1]);b．printf(“%c”,class[2].name[0]);

c．printf(“%c”,class[3].name[0]);d．printf(“%c”,class[2].name[1]);

The purpose of the 18 break statement is (c).

a skips the next phrase b b. jumps out of the program.

c Jump out of this loop and no longer execute the loop d is an empty statement and does nothing.

19.Procedure (c) below.

main( ) * line 1 *

int a[3]=,i;Line 2

for (i=0 ;i<3 ;i++)scanf(“%d”,&a[i]);Line 3

for (i=0 ;i<4 ;i++)a[0]=a[0]+a[i];Line 4

printf (“d”,a[0]);Line 5

Line 6 *

A There is no error B There is an error in line 2 C There is an error in line 4 D There is an error in line 6.

20 The meaning of the execution function fopen ("w+") is (c).

A opens a file as a read and B opens a file as a write.

c Create a file that is both readable and writable d Create a writable file only.

21.When you define a shared size variable, the number of bytes of memory allocated to it is (a).

a The number of bytes occupied by the member who shares the size variable, the member with the largest number of bytes.

b The number of bytes occupied by the member with the least number of bytes among the members who share the body size variable.

c The sum of the bytes occupied by all members of the common body shape variable.

d The sum of the bytes occupied by all members of the common size variable is added by 1

22 The function of the continue statement is (c).

A skips the next statement b b. Jumps out of the program.

c Jump out of this loop and execute the next round of the loop d is an empty statement and does nothing.

Each cycle x[n] is added once, then count the number of s[k] elements, 0 0, 4 1, 2 2, 2 3.

So it's 0 4 2 2
