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
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
举一反三
- 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fread函数的调用形式中,参数类型正确的是( )。 A: fread(char *buf, int size, int count, FILE fd); B: fread(int count, char *buf, int size, FILE fd); C: fread(int size, char *buf, int count, FILE fd); D: fread(int size, int count, char *buf, FILE fd);
- 以下read函数的调用形式中,参数类型正确的是( )。 A: read(intfd,char*buf,intcount) B: read(int*buf,intfd,intcount) C: read(intfd,intcount,char*buf) D: read(intcount,char*buf,intfd)
- 下列哪条语句是正确的?_______________ 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;
- 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;}
