一、C 語言中，傳遞參數的方式為「以值傳遞」（Pass by Value），試寫出下列程式之執行結果：（20 分） #include void exchange1 (int a, int b) { int tmp; tmp = a; a = b; b = tmp; } void exchange2 (int *a, int *b) { int tmp; tmp = *a; *a = *b; *b = tmp; } main () { int x, y; x = 1; y = 0; exchange1(x, y); printf(“x is %d\n”, x); printf(“y is %d\n”, y); exchange2(&x, &y); printf(“x is %d\n”, x); printf(“y is %d\n”, y); }
