求助！一個C語言小程序.有道例題：有1、2、3、4個數字，能組成多少個互不相同且無重複數字的三位數？都是多少？ 程序如下： main() { int i,j,k; printf(\"\\n\"); for(i=1;i<5;i++)　　　 　for(j=1;j<5;j++)　 　　for (k=1;k<5;k++) 　　　{ 　　　　if (i!=k&&i!=j&&j!=k) 　　　 　　　　printf(\"%d,%d,%d\\n\",i,j,k); 　　　} } 對於其中的:if (i!=k&&i!=j&&j!=k) 這句不太明白，請高手解答下！

也就是說應該是：
if (i!=k && i!=j && j!=k)這麼分開吧，唉，對運算符的優先級還是有點暈哈。
3樓的朋友，不知道你編譯完怎麼成了那樣，是不是跟你將它放在桌麵上了有關係？

if (i!=k&&i!=j&&j!=k) 　表示i不等於k且i不等於j且j不等於k 也就是各數字不重複."!="表示不等於的意思
第一次回答問題,不知道,你是否滿意
