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);}
举一反三
- 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); }
- 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); }
- 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);}
- 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;}
- 以下程序运行结果是（）。#includeiostreamusing namespace std;void sub(int x, int *y,int *z){*y=*y-10;*y=*z+x;}int main(){int a=10,b=12,* pa,* pb;pa=a;pb=b;sub(b-a,pa pa);coutaendl;return 0;} A: 9 B: 4 C: 7 D: 2
