‎以下代码的输出是 ：​‎void swap( int *pa, int *pb ) { int pt; pt = *pa, *pa = *pb, *pb = *pa; } int main(void) { int x=1, y=2; swap(&x, &y); printf("%d%d", x, y); }​‎​

以下代码的输出是 ：void f( int *pa, int *pb ) { int pt; pt = *pa, *pa = *pb, *pb = *pa; } int main(void) { int x=1, y=2; f(＆x, ＆y); printf("%d%d", x, y); }

中国大学MOOC: 以下代码的输出是 ：voidswap(int*pa,int*pb){intpt;pt=*pa,*pa=*pb,*pb=*pa;}intmain(void){intx=1,y=2;f(＆x,＆y);printf("%d%d",x,y);}

下列程序运行后的输出结果是：_____#includestdio.hvoid fun( int *pa, int pb ) { int pt; pt = *pa, *pa = pb, pb = pt;}int main( ){ int x=1, y=2; fun(x, y); printf(%d, x==y); return 0;}

中国大学MOOC: 以下程序段的输出是( )。void swap(int *pa, int *pb) { int pt; pt = *pa, *pa = *pb, *pb = *pa;}int main(void){ int x=1, y=2; swap(&x, &y); printf(%d %d, x, y);}

有以下程序#include [stdio.h] void sub(double a,double *pb); int main(){ double x,y; scanf("%lf%lf",&x,&y); sub(x,&y); printf("x=%fy=%f\n",x,y); } void sub(double a,double *pb){ a=a-*pb; *pb=*pb-a; }程序运行时输入: 10.2 3.5[回车]，则输出结果为( )。 A: x=10.200000 y=-3.200000 B: x=6.700000 y=-13.700000 C: x=7.000000 y=-3.500000 D: x=13.400000 y=-7.000000

If your portfolio standard deviation is 14% and risky asset standard deviation is 28%, what is the weight of risky asset in your portfolio? (Hint: Remember the y!) A: 0.5 or 50% B: 1 or 100% C: 0.1 or 10% D: .44 or 44%

若有语句：int a,b; int *pa,*pb; pa=&a; pb=&b; 正确的输入语句是（） A: scanf("%d%d",x, y); B: scanf("%d%d",pa,pb); C: scanf("%d%d",&pa,&pb); D: scanf("%d%d",*pa,*pb);

设需求交叉价格弹性EAB=(PB/(QA)(¶QA/¶PB)=-0.4,则PB上涨1%时,QA下降______

下面代码的执行结果为（ ）。def f(values): values[0] = 44v = [1, 2, 3]f(v)print(v) A: [1, 44] B: [1, 2, 3, 44] C: [44, 2, 3] D: [1, 2, 3]
