while n is put from keyboard. 22.
Write a program that prints the even numbers from 1 to 100. 23.
Write a program that prints the odd numbers from 1 to 100. 24.
Input two numbers x and y from keyboard, find the maximum. 25. Man retires at 60, female retires at 55, please input man or female’s age and sex, then judge whether he or she retires or not. Take F or f to indicate female, M or m to indicate male. 26.
Input three integers a, b and c from keyboard, calculate the roots of equation ax2+bx+c=0(a≠0), maintaining 2 digits after decimal point.. 27.
Input a 3-digit number from keyboard, and then judge whether it is a daffodil number. Daffodil numbers are those numbers, which are 3-digit numbers, sum of cubic of each digit equals to the number, for example, 153＝13+53+33 28. Write a program according to the following function, which requires input x from keyboard, then output the corresponding y.
29. Write a program, input three edges of the triangle, and figure out its area. Hints, sum of every two edges must be greater than the third edge, for unreasonable edges, error message should be given, 30. Input a character from keyboard, if it is a lowercase, change into upper case, if it is an uppercase, change into lower case, else print the original character. 31. The following formula converts the given temperature in Fahrenheit to Celsius
, in which, C shows temperature in Celsius, F shows temperature in Fahrenheit. Write a program, input the given temperature in Fahrenheit, and then output in Celsius, maintaining 2 digits after decimal point.

关于c语言很简单的一个问题！！
三． 已知int a=3,b=4,c=5,x,y;求下列各表达式的值（1） a+b&c&&b==c（2） a||b+c&&b-c（3） !(a&b)&&!c||1（4） !(x=a)&&(y=b)&&0（5） !(a+b)+c-1&&b+c&#47;2谁能告诉我答案？？还有解题的思路（怎么想的或是用c编程的程序怎么具体输入）谢谢！
我看书了可是看不明白阿
马上就期中考试了 这是老师给的复习题。大家帮帮忙吧~~~ 如果编程解决的话应该输入完整的程序是什么？？谢谢

我算出来得0 1 1 0 1，知道运算符的意义和顺序就能算了。逻辑非、加和减同级、逻辑与和逻辑或同级；后两个同级间都是从左往右算。你自己算算，我不一定对。
具体答案我不告诉你了！你看看书上各种算符的优先级，先计算优先级高的，自己算算更有好处，这样有助于自己的学习！记得加分哟！

出门在外也不愁关于C语言的题目，帮忙解答啊，答案是9，这是参考答案，但网上很多人说是8，也有说9的_百度知道
关于C语言的题目，帮忙解答啊，答案是9，这是参考答案，但网上很多人说是8，也有说9的
若管篓蒂男郦萌垫职叮涩以下变量均是整型，且num=sum=7；则执行表达式sum=num++，sum++,++num后sum的值为（）。
num=sum=7;sum=num++; ==& sum = 7, num =8;sum++;===&sum =8;++ ===& num =9;sum = 8;--------------------------------但是，这是表达式，，表达式运算时，sum=num++，sum++,++num；赋值高,逗号要低于赋值，结果还是不变；若是sum=（num++，sum++,++num）；sum = num = 9;

如果你的代码如下：#include &stdafx.h&int _tmain(int argc, _TCHAR* argv[]){
int sum = 7;
int num = 7;
sum = num++;
printf(&sum =%d&#92;n&,sum);
printf(&num =%d&#92;n&,num);
return 0;}那么输出为：sum = 8num = 9
觉得是9吧。。 sum=num++sum=7+1sum++sum=9++num和sum无关
个人认为num的值是9，sum的值是8.++运行符如果在变量后面的话,就会先计算这个表达式的值后再运行++运算有关++运算符的优先级,你可以这样理解当++在变量前面的时候,处于第二优先级,当++在变量之后时,你可以将++的优先级看成最低级的,比逗号运算符的优先级还低
sum=num++ -- sum=7,num=8sum++ sum=8num++ num=9sum最后的值为8
在这一步，num先把值赋7给sum,然后自身在加1，这时候sum=7，num=8，执行完sum
num后sum=8，num=9. 我也想不出来sum=9是怎么算的。
9,因为等号的优先级最低了
9啊。。逗号要低于赋值，结果还是不变
是8 ，VC运行的结果。
