char a[][2][100]={{"姓名","李成龙"},{"年龄","24"},{"姓名","李成龙"},{"年龄","24"},{"性别","男"},{"籍贯","长沙"},{"年龄","24}};
char (*b)[2][100]=b;
我用一个指针b指向一个定义好的数组a,从这个指针标量中得到数组a的长吨呢?
我用sizeof()但用不好,没得出来,请你们帮帮我好吗?

strlen函数

请问怎么用阿？

strlen我试过了，但不能用？

char a[][][]={{"姓名","李成龙"},{"年龄","24"},{"姓名","李成龙"},{"年龄","24"},{"性别","男"},{"籍贯","长沙"},{"年龄","24}};
这样就应该能用len()计算长度了
