main { int x=3,y=0; y=++x*--x; printf(“y=%d,x=%d\n”,y,x); }输出结果是：
举一反三
- 下面程序的输出结果是 。 #include int main (void) { int x=2,y,z; x*=3+2;printf("%d\n",x); x*=y=z=4;printf("%d\n",x); x=y=z;printf("%d\n",x); x=(y=z);printf("%d\n",x); return 0; }
- 以下程序没有语法问题的是（） A: B: include<;stdio.h>;int main( ){int x , y = 5 ; printf( "%d\n" , x / y ) ; return 0 ;} C: D: include<;stdio.h>;int main( ){int x = 3 ;y = 5 ; printf( "%d\n" , x / y ) ; return 0 ;} E: F: include<;stdio.h>;int main( ){int x = 3 ,y ; printf( "%d\n" , x / y ) ;y = 5; return 0 ;} G: H: include<;stdio.h>;int main( ){int x = 3 , y = 5 ; printf( "%d\n" , x / y ) ; return 0 ;}
- 以下程序输出的结果是____________.#include [stdio.h]int main(){ int x=30,y=7; x=y=x%y; printf("%d\n",x); return 0;}
- 以下程序的输出结果是（ ）。main(){ int x=1,y=2; void swap(int x,int y); swap(x,y); printf("x=%d,y=%d\n",x,y);}void swap(int x,int y){ x=3,y=4;} A: x=3,y=4 B: x=1,y=2 C: x=3 y=4 D: x=1 y=2
- 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
