写出与表达式z = x=y x y 等价的if语句并上机验证。

if (x >= y) { z = x; } else { z = y; }

验证代码：

#include using namespace std;

int main() { int x = 5; int y = 3; int z = (x >= y ? x : y);

cout << "z = " << z << endl;

if (x >= y) {
    z = x;
} else {
    z = y;
}

cout << "z = " << z << endl;

return 0;

}

输出：

z = 5 z = 5
