c程序模拟试题（C simulation test） There are 4 major items in this volume: A single choice (a total of 20 items, each item of 20 points, a total of 400 points) 1, if the program already contains the header file stdio.h, in the following options, the correct use of pointer variables of the program segment is (B) A, int, *i=NULL; scanf (%d, I); B, float, *f=NULL; *f=10.5; C, char, t=m, *c=t; *c=t; D, long, *L; L=\0; 2, C has been defined as a character variable, and the following statement is correct (C) A, c=97; B, c= 97; C, c=97; D, c=, a.; 3, there are defined statements: int, x, y; if you want to pass scanf (%d,%d), x, y); the statement makes the variable x to get the value of 11, the variable y to get the value of 12, the following four groups of input form, the error is (A) A, 11 12, enter B, 11, 12, carriage return C, 11,12, enter D, 11, enter, 12, enter 4. The correct set of statements in the following options is (C) A, char, s[8]; s={Beijing}; B, char, *s; s={Beijing}; C; char s[8]; s=; Beijing; D, char *s; s= Beijing; 5, the following can not be defined as the user identifier is (D) A, Scanf B, Void, C, _3com_ D, int The option for 6 or less to define a two-dimensional array is (D) A, int, a[2][2]={{1}, {2}}; B, int, a[][2]={1,2,3,4}, C, int, a[2][2]={{1}, 2,3}; D, int, a[2][]={{1,2}, {3,4}}; 7, there are statements defined: int, a=1, b=2, c=3, X; then the following options in the program segment after the implementation, the value of X is not 3 is (D) A, if (ca) x=1; else if (ba) x=2; else x=3; B, if (a3) x=3; else if (a2) x=2; else x=1; C; if (a3) x=3; if (a2) x=2; if (bc) x=c; D, if (ab) x=b; if (a1) x=1; if (ca) x=a; 8, the following functions defined: void fun (int, N, double, x) {...... } if the variables in the following options are properly defined and assigned, the correct call to function fun is C A, fun (int, y, double, m); B, k=fun (10,12.5), C, fun (x, n); D, void, fun (n, X); 9. The following incorrect escape characters are (C) A, \ \ B, C,074\ D
