main() { unsigned char a,b; a=4|3; b=4&3; printf("%d %d\n",a,b); }执行后输出结果

main(){ char ch ; scanf(%c,&ch); ch=(ch>='a'&&ch 求补码怎么求的...#include #include void main (){unsigned short int a;unsigned short int getbits(unsigned short);printf ( input an octal number:);scanf (%o,&a);printf (%o ,getbits(a));}unsigned short int getbits (unsigned short value){u C语言~main( ) { char ch; ch=getchar( ); if (ch>='A' && ch #include main() {char ch; ch='A'+'5'-'3'; printf(%d,%c ,ch,ch); 关于单片机c语言有几个句子不明白,望详解,（1）#define nop() _nop_(); 我只用过#define unit unsigned int（2）void main(void) 括号中加void是什么意思（3） return(ch);（4）for (;data_o==1;) 原先我认为加两个等 谁能告诉我以下程序结果,unsigned fun6(unsigned num){unsigned k=1;do{k*=num%10;num/10;}while(num);return(k);}main(){unsigned n=26;printf(%d ,fun6(n));}是c语言题 main() { char ch; ch='H'-'A'+'0'; printf(%c ,ch); } main( ) {unsigned int a=3,b=10; printf(%d/n,a1); } 一道C语言题目~求教!#include #include int main(){unsigned x = 10;getbits(x,4,3);return 0;}unsigned getbits(unsigned x,int p,int n){return (x >> (p+1-n) & 0 c语言中 (ch-ch%32+26)-(ch%32-1));怎么理解?具体问题是这样的：main(){char ch;scanf(%c,&ch);if(ch>'A'&& ch=‘a’&& ch #include void main() { unsigned char a,b; a=4|3; b=4&3; printf(%d,%d,a,b); } 下列程序的运行结果是【1】,main(){unsigned x1; int b=-1;x1=b;printf(%u,x1);} 求解main(){unsigned a=32768;int b;b=a;printf(b=%d ,b);} temp=0xfe什么意思在c语言中程序出现的有什么含义?#include sbit P1_7=P1^7;unsigned char code table1[]={0x06,0x5b,0x4f,0x66,0x6d};unsigned char code table2[]={0x76,0x79,0x38,0x38,0x3f};unsigned char code table3[]={3,4,5,6,7};unsigned ch c++,题目我看不懂得,希望有朋友能简单讲解下以下程序的输出结果是______.#include unsigned fun6(unsigned num){ unsigned k=1;do{k*=num%10; num/=10;}while (num);return k;}main(){ unsigned n=26;printf(“%d ”,fun6(n));} #include main() {unsigned int a=65535; printf(a=%d ,a); } 运算结果 a=-1#includemain(){unsigned int a=65535;printf(a=%d ,a);}运算结果a=-1为什么是等于-1呢? C++里的flag是什么意思?Status InputString(unsigned char *str) {int flag=0;unsigned char ch;str[0]=0;//接受输入while((ch=getchar())!=' ') {if(flag==1) {flag=2;break;}str[0]++;if(str[0]==255) flag=1;str[str[0]]=ch;}if(flag==2) {ErrorTip(Over #include #include void main() { char ch; int a,s,k,t; while(ch=getchar()!= )
