int b=0,a=1;b= ++a + ++a; what is the value of b? what is the ...

1 It would seem that having a sequence point is immaterial in the expression b=++a + ++a; That is, whether the first ++a is evaluated first or the second ++a is evaluated first in either case a is incremented twice and then the + operator takes effect, so the eventual equation is either b = 2 + 3; or b = 3 + 2 thus b = 5.

Terms in this set (29) int a = 0; int b = 0; while (a < 5 && b < 3) { System.out.println (a + " " + b);a++;b++; } What is output?

Pre-increment and Post-increment Operators in C/C++

a: 11, b: 11 Post-increment Operator The Post-increment operator increases the value of the variable by 1 after using it in the expression, i.e. the value is incremented after the expression is evaluated. Syntax a++ Example Input: a = 10; b = a++; Output: a = 11 b = 10 In the expression b=a++, a++ will be evaluated after assigning the value of ...

If int a=2, and int b=3, what value would the following ... - Brainly

Answer: +1 If int a=3; int b=2; b=a++ cout <<++b,what is the output? c++ 11th March 2017, 3:04 PM Wis Vaurasi 8 Answers NEW ANSWER Sort by: Votes +14 The output will be 4. Here is how the logic works on your case: Given : a = 3 b = 2 Then : b = a++ which means take a value to b and then increment the a value. so b value is same as a (before the increment), so with that statement, their value ...

若int a = 0, b = 1, c = 2,则逻辑表达式a++ && b++ || (c -= 2)执行之后

10 11 12 13 结果如下: 2021年6月26日补充: 在c语言中,&&与||有段路特性,解释如下: 1、条件1&&条件2 如果条件1为假,也就是0,那么代码将不执行条件2,因为0与任何条件都是0 2、条件1||条件2 如条件1的结果为真,也就是1,那么代码将不执行条件2,因为1或任何 ...

若有定义int a=1,b=2;,执行语句a++>=b&&b++; 之后,变量a和b的值分别为2,2 b为什么还是2 求答案

本回答由达人推荐 醉饮千觞不知愁 2017.03.18 回答 因为编译器在判断 a++>=b 是逻辑假后就不会再计算后面的b++了 因为逻辑假与逻辑真或逻辑假相与都是逻辑假所以就不会计算了。

int a=0,b=0,c=0; c=++a||b++;b=?a=? - CSDN

在这个程序段中,首先声明了三个变量: int a = 1, b = 2, c;,其中 a 被初始化为1, b 为2,而 c 没有直接初始化,但后面有一个赋值表达式。 表达式 c = a > 0 || ++b; 有两部分: a > 0 是一个条件判断,因为 a 是1,这个条件是真(true),即返回 1。 ++b 是一个自增操作,它会先计算 b 的当前值(这里是2 ...

x=a>b++?a++:b++是什么意思 int x,a=3,b=2;_百度知道

a>b++?a++:b++ 判断a>b++?是否成立,成立则执行a++,不成立则执行b++,这个题目中3>2+1不成立,所以执行b++,不执行a++,a后来还是3,但是在x=a>b++中已经执行了一次b++,所以b相当于自增了2次。
