请问methematica的计算结果比如:B=1;C=2;A=B+C,如何直接显示为数值结果而不是包含符号变量?
先定义名称
A=1
B=2
C=3
D=4
E=5
就可以直接用字母计算了.

兄弟,你这是c语言的题吗?如果是的话,第一个空为3,第二个空为3第一个空解答:1/2,因为1和2皆为整数,所谓1/2的结果为0第二个空解答:&&运算有一种特殊情况就是如果&&前面的前面的执行结果为假时,则不执行后面的运算了,而a>b此时为假,所以c++不执行,故c值不变仍为3各种语言的“早安”怎么说?
中文:早安 1、日语:早安:おはよう 2、冰岛语 Góean morgunn! gou-than mor-hhun 3、丹麦语 God morgen! go-the mor-gen 4、瑞典语 God morgon! goo-d mor-on 5、荷兰语 Goede morgen! hoo-de mor-hen 6、德语 Guten Morgen! Gu-ten mor-gen 7、爱尔兰盖耳语 Dia dhuit! di-ya...
