假设 int x=4，y=100，下列语句的循环体共执行了多少次： while(y/x>3) { if(y%x>3) x=x +1; else y=y/x; }
举一反三
- 假设 int x=4,y=100,下列语句的循环体共执行()次。While(y/x>3){if(y%x>3){x=x+1;}else {y=y/x;}} A: 1 B: 2 C: 3 D: 4
- int x=5, y=20;do{ y -= x; x += 2;}while(x<y)以上循环体执行（）次 A: 0 B: 1 C: 2 D: 3
- 执行以下语句的结果为______。 int x=3,y;int*px=&x;y=*px++; A: x=3,y=4 B: x=3,y=3 C: x=4,y=4 D: x=3,y不知
- 已知int x=3,y=4;，写出下列表达式的值 (1) (x,y) (2) x>y?x:y (3) x?y:x (4) (x>y)?(y>=2)?1:2:(y>x)?x:y
- 如下C程序的输出是什么？#include [stdio.h]void Func1 (int x, int y);void Func2 (int *x, int *y); int main() { int x = 3; int y = 4;Func1 (x, y); printf ("x = %d, y = %d\n", x, y);Func2(&x, &y); printf ("x = %d, y = %d\n", x, y);} void Func1 (int x, int y) { x = x + y; y = x - y; x = x - y; printf ("x = %d, y = %d\n", x, y);} void Func2 (int *x, int *y) { *x = *x + *y; *y = *x - *y; *x = *x - *y;;} A: x = 3, y = 4x = 3, y = 4x = 3, y = 4 B: x = 4, y = 3x = 4, y = 3x = 4, y = 3 C: x = 3, y = 4x = 3, y = 4x = 4, y = 3 D: x = 4, y = 3x = 3, y = 4x = 4, y = 3
