问题描述
我需要一个char数组转换为字符串。事情是这样的:
字符数组[20];字符字符串[100];数组[0] ='1';阵列[1] =7;阵列[2] =8;阵列[3] ='。';阵列[4] ='9';...我想获得类似的东西:
字符字符串[0] =数组//它被存放178.9 ....位置[0]解决方案
你是说你有这样的:
字符数组[20];字符字符串[100];数组[0] ='1';阵列[1] =7;阵列[2] =8;阵列[3] ='。';阵列[4] ='9';和你想有这样的:
串[0] =178.9; //它被存储178.9 ....在位置[0]您不能有。一个char拥有1个字符。而已。A串在C是字符数组后跟一个标记字符(NULL结束符)。
现在,如果你想第一个X字符出阵列复制到字符串你可以做到这一点与的memcpy():
的memcpy(字符串,数组,X);字符串[X] ='\\ 0';I need to convert a char array to string. Something like this:
char array[20]; char string[100]; array[0]='1'; array[1]='7'; array[2]='8'; array[3]='.'; array[4]='9'; ...I would like to get something like that:
char string[0]= array // where it was stored 178.9 ....in position [0]解决方案
You're saying you have this:
char array[20]; char string[100]; array[0]='1'; array[1]='7'; array[2]='8'; array[3]='.'; array[4]='9';And you'd like to have this:
string[0]= "178.9"; // where it was stored 178.9 ....in position [0]You can't have that. A char holds 1 character. That's it. A "string" in C is an array of characters followed by a sentinel character (NULL terminator).
Now if you want to copy the first x characters out of array to string you can do that with memcpy():
memcpy(string, array, x); string[x] = '\0';
