A: int count = 5; int* x = &count;
B: int count = 5; int x = &count;
C: int count = 5; int& x = &count;
D: int count = 5; int** x = &count;
举一反三
- 48. 以下Java代码片段编译运行的结果是。 int [] a = {1,2,3,4,5}; for (int count = 0 ; count<5; count ++) System.out.print(a[count++]) int [] a = {1,2,3,4,5}; for (int count = 0 ; count<5; count ++) System.out.print(a[count++])
- 下面的代码段执行之后count的值是什么( ) int count = 1; for(int i = 1; i <= 5; i++) { count+= i; } System.out.println(count); int count = 1; for(int i = 1; i <= 5; i++) { count+= i; } System.out.println(count);
- 下面的代码段执行之后count的值是什么( ) int count = 1; for (int i = 1; i <= 5; i++) { count += i; } System.out.println(count);
- 以下 read 函数的调用形式中，参数类型正确的是（） 。 A: ead(int fd,char *buf,int count) B: ead(int *buf,int fd,int count) C: ead(int fd,int count,char *buf) D: ead(int count,char *buf,int f
- 以下read函数的调用形式中参数类型正确的是(). A: ead(int fd,int count,char *buf) B: ead(int *buf,int fd,int count) C: ead(int fd,char *buf,int count) D: ead(int count,char *buf,int fd)

以下哪个方法是正确的？ A: public static int Sum(int n, params int[] val){ int count = 0; foreach (int a in val){ count = count + a; } return count + n;} B: public static int Sum(params int[] val, int n){ int count = 0; foreach (int a in val){ count = count + a; } return count + n;} C: public static int Sum(params int[] v1, params int[] v2){ int c1 = 0, c2 = 0; foreach (int a in v1){ c1 = c1 + a; } foreach (int a in v2){ c2 = c2 + a; } return c1 + c2;} D: public static int Sum(params int[] v, char ch){ int c = 0; foreach (int a in v){ c = c + a; } return c + ch;}

写出下列程序的输出结果 public class Test { public static void main(String[] args) { Count myCount = new Count(); int times = 0; for(int i=0;i<100;i++) increment(myCount , times); System.out.println(“count is” + myCount.count); System.out.println(“time is”+ times); } public static void increment(Count c , int times) { c.count++; times++; } } class Count { public int count; Count(int c) { count =c; } Count() { count =1; } }
