我想用传递引用方法显示 x,y,z 值怎么做？

• 什么是传值结果？

    void f1(int x, int y, int z){
        x = y + z;
        y = z + 1;
        printf("x: %d y:  %d z: %d",x,y,z);
    }
  
    int main(int argc, char *argv[]) {
        int r = 5;
        int t = 10;
        int k = 15;
        f1(r, t, t + k);
        printf(" r : %d t:  %d k : %d",r,t,k);
    }
