gotoagain;if(ch=='N'||ch=='n,intcurrent);

CH2=CH-CH(CH3)-CH(OH)-CH3怎么命名?(CH3)2N-CHO怎么命名?
main() { char ch; ch='H'-'A'+'0'; printf("%c\n",ch); }
C语言中n = ch -
C语言~main( ) { char ch; ch=getchar( ); if (ch>='A' && ch
CH3-CH=CH-CH=CH-CH3是否存在?
已知char ch;执行语句“while(ch=getchar()!='\n');”时输入“abcde”后,变量ch的值
#include main() {char ch; ch='A'+'5'-'3'; printf("%d,%c\n",c
写出下列聚合物单体的结构简式:1.[-CH2-CH=CH-CH2-CH2-CH-CH-]n I CN 2.O II [-
while((ch=getcher())!='\n') 是什么意思啊
while((ch=getchar())!='\n')是什么意思
CH3-CH=CH-C≡CH 如何命名?
