下列程序运行后的输出结果是:_____ #include<stdio.h> void 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; }

下列程序运行后的输出结果是:_____ #include<stdio.h> void 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; }


参考答案和解析
D 本程序中通过DATA语句对数组B赋值的结果为矩阵DO循环语句的功能是将数组B的第2列的元素的值依次赋值给数组A。因此,A(1)=4、A(2)=5、A(3)=6,所以格式输出数组A后输出的结果为456。
