Question

下面c语言程序哪里写错了？电脑提示： Lvalue required in function main

# include <stdio.h>
void main()
{ int a,b,c;
char yes,no;
scanf("%d,%d,%d",&a,&b,&c);
(a%2)||(b%2)||(c%2)!=0? no : (a%2)&&(b%2)&&(c%2)=0? no : (a+b+c)%2!=0? no : yes;
}

Answer 1

这条语句中有错：(a%2)||(b%2)||(c%2)!=0? no : (a%2)&&(b%2)&&(c%2)=0? no : (a+b+c)%2!=0? no : yes;
其中的 (a%2)&&(b%2)&&(c%2)=0错了，应该是： (a%2)&&(b%2)&&(c%2)==0这样的。“=”是表示赋值，和数学上的“=”不同应注意，C语言中的等于是“==”。

Answer 2

(a%2)||(b%2)||(c%2)!=0? no : (a%2)&&(b%2)&&(c%2)=0? no : (a+b+c)%2!=0? no : yes;错了。赋值符应为“=="

Answer 3

#include <stdio.h>
void main()
{ int a,b,c;
char yes,no;
scanf("%d,%d,%d",&a,&b,&c);
(a%2)||(b%2)||(c%2)!=0? no : (a%2)&&(b%2)&&(c%2)!=0? no : (a+b+c)%2!=0? no : yes;
}

Answer 4

(a%2)&&(b%2)&&(c%2)=0?中的“=”错误
