floata，b，c，问等式（a+b）+c==（b+a）+c和（a+b）+c==（a+c）+b能否成立？

#include main(){ float a,b,c,t;a=3;b=7;c=1;if(a>b){t=a;a=b;b=t;}if(a>c){t=a;a=c;c=t;}if(b>c){t=b;b=c;c=t;}printf(%5.2f,%5.2f,%5.2f,a,b,c);}运行结果为（ ）
有以下程序段 int a, b, c; a=10; b=50; c=30; if (a>b) a=b, b=c; c=a; printf(a=%d b=%d c=%d”, a, b, c); 程序的输出结果是（ ）。
语句后,a,b,c的值分别为（ ）。int a,b,c;a=b=c=1;++a||++b&&++c;
当a,b,c的值分别为3，4，5时，以下各语句执行后a，b，c的值为多少（ ）if (a>c){a=b; b=c; c=a;}else{a=c; c=b; b=a;}printf(“%d,%d,%d”,a,b,c);
That was not a good start to what, hopefully, will be a successful business meeting.
If we sit down and study it in a rational, objective ( ), maybe we could find a way out.
Maybe I should give her a chance.
设有定义：int a=1,b=2,c=3;以下语句中执行效果与其他三个不同的是A) if(a>b) {c=b,a=b,b=c;}B) if(a>b) {c=a,a=b,b=c;}C) if(a>b) c=a;a=b;b=c;D) if(a>b) {c=a;a=b;b=a;}
a、b、c三个数，已知a×b＝24，a×c＝36，b×c＝54，求a+b+c＝()。
表示关系a≤b≤c的C语言表达式为（)。A．（a＜=B) &&（b＜=C)B．（a＜=B) and（b＜=C)C．（a＜=b＜=C)D．（a＜
根据所听到的内容作答_____。 A)Smoking is the only bad habit the man should change． B)She doesn’t love the man as deep as before． C)She doesn’t want to have a baby if the man smokes． D)Maybe she will leave the man if he continues to smoke．
设a，b，c为单位向量，且满足a+b+c=0，求a·b+b·c+c·a
设为一个半群,a,b,c为S中的给定元素.证明:若a,b,c满足a*c=c*a,b*c=c*b那么（a*b)*c=c*（c*b).
General Electric's Visilog is being developed, hopefully, to permit a planned moon-probe rocket to make a soft landing on the moon's surface.
【单选题】5、设[{a , b , c}，*]为代数系统，*运算如下： * a b c a a b c b b a c c c c c 则零元为（）。
（） Maybe you should see a doctor.
有以下程序段：int a,b,c;a=10;b=20;3=30;a=b;b=c;c=a;printf(“a=%d,b=%d,c=%d\n”,a,b,c);
有以下程序：includeint main（）{ int a, b, c[10] = { 0,1,2,3,4,5,6,7,8,9 }; for （a = 0; a＜10; ++a） { for （b = 0; b＜5 – a; ++b）{ if （c[b] ＜ c[b+1]） { c[b] += c[b + 1]; c[b + 1] -= c[b]; c[b] += c[b +
当a，b，c的值分别为3，4，5时，以下各语句执行后a，b，c的值为多少？if（a＞c）{a=b;b=c;c=a;}else {a=c;c=b;b=a;}（）
设A={a，b，{a，b}，c}，B={b，{b，c}，{a}}，求A－B，B－A，A B．设A={a，b，{a，b}，c}，B={b，{b，c}，{a}}，求A-B，B-A，A B．
We haven't our______minds yet. Maybe to a restaurant，maybe to a movie first.
