7、交换两个整数 int main( ) { int x(5) , y(10) ; cout int x=-5,y;cout #include int main( ){int c;cout int x=10,y=3,z; cout 运行vc++时 #include int main() { cout #include using namespace std; int main() { cout fun(int x,int y,int z) {z=x*x+y*y;} main() {int a=31; fun(5, #include void mian() { int x,y; x=3; y=5*(++x); cout main() { int x=10; int y=x++; printf("%d,%d\n",(x++,y),y++); C++有道题看不懂,#include int func(int a,int b);int main(){cout #includevoid main(){int max(int x,int y);int a,b,c;scanf("%d #include int main() { int max; int x,y,z; if x>y printf("max
