将一个数组拆分为两个数组,一个为奇数数组,一个为偶数数组: 实例 #include<stdio.h>intmain(){intarray[10]={0,1,2,3,4,5,6,7,8,9};inteven[10],odd[10];intloop,e,d;e=d=0;for(loop=0;loop<10;loop++){if(array[loop]%2==0){even[e]=array[loop];e++;}else
stringuserName ="<Type your name here>";stringdateString = DateTime.Today.ToShortDateString();// Use the + and += operators for one-time concatenations.stringstr ="Hello "+ userName +". Today is "+ dateString +"."; Console.WriteLine(str); str +=" How are you today?"; Console.Writ...
1.3 strcat函数(字符串追加函数) Appends a copy of the source string to the destination string. The terminating null character in destination is overwritten by the first character of source, and a null-character is includedat the end of the new string formed by the concatenation of both in dest...
char*strcpy(char*destination,constchar*source); Copies the C string pointed by source into the array pointed by destination, including the terminating null character (and stopping at that point).简单理解就是字符串的拷贝,不过拷贝要注意下面几个点: 源字符串必须以 ‘\0’ 结束。 会将源字符串中的...
C preprocessor and concatenation http://stackoverflow.com/questions/1489932/c-preprocessor-and-concatenation I am trying to write a code, where name of functions are dependent on the value of a certain macro variable. To be specific, I am trying to write a macro like this: ...
When you define a macro, you request concatenation with the special operator`##'in the macro body. When the macro is called, after actual arguments are substituted, all`##'operators are deleted, and so is any whitespace next to them (including whitespace that was part of an actual argument...

Appends a copy of the source string to the destination string. The terminating null character in destination is overwritten by the first character of source, and a null-character is included at the end of the new string formed by the concatenation of both in destination. ...
Copies the C string pointed by source into the array pointed by destination, including the terminating null character (and stopping at that point). 源字符串必须以 '\0' 结束。 会将源字符串中的 '\0' 拷贝到目标空间。 目标空间必须足够大,以确保能存放源字符串。 目标空间必须可变。 学会模拟实现...
