设iX=2,iY=3, ch='a',则表达式iZ = (iX || iY)&&(ch>'A')的值是1

下面程序的运行结果是 iX=80,iY=25____。void main(){ int iX,iY;iX=80;iY=25;printf("iX=%d,iY=%d\n",iX,iY);printf("iX/iY=%d,iX%iY=%d\n",iX/iY,iX%iY);}

iX=2,iY=3,ch='a',表达式iZ=(iX||iY)&&(ch>'A')的值是。 A: true B: false C: 0 D: 1

void main() { int iX,iY,iM,iN; iX=10;iY=20; iM=iX++;iN=++iY; printf("iX=%d,iY=%d,iM=%d,iN=%d",iX,iY,iM,iN); iM=iX– –;iN=– –iY; printf("iX=%d,iY=%d,iM=%d,iN=%d",iX,iY,iM,iN); }

iX=2，iY=3，ch='a'，表达式iZ=(iX||iY)&amp;&amp;(ch>;'A')的值是 A: true B: false C: 0 D: 1

#include "stdio.h" void main() { int iX,iY,iM,iN; iX=10;iY=20; iM=iX++;iN=iY++; printf("iX=%d,iY=%d,iM=%d,iN=%d",iX,iY,iM,iN); iM=iX--;iN=--iY; printf("iX=%d,iY=%d,iM=%d,iN=%d",iX,iY,iM,iN); }

147除以3等于49。

If<em>x</em>-3＝8,then(<em>x</em>-4)²＝______. A: 25 B: 49 C: 64 D: 81 E: 121
