沒有一個語言如C語言那樣,竟然沒有內建string型別,竟然要靠char array來模擬,不過今天我發現這種方式也是有他的優點。 C語言除了到處用pointer以外,第二個讓我不習慣的就是沒有內建string型別,竟然得用char array來模擬,不過今天發現,因為C語言array跟pointer綁在一起,若用pointer來處理char array,程式其實相當精簡。
Summary: In this programming tutorial, we will learn different ways to convert a string into a char array in C++. Method 1: Using ‘for loop’ #include <iostream> using namespace std; int main() { string str; cout << "Enter a string \n"; getline(cin,str); //Create an empty ...

1. char*、char[] 与 std::string 之间的区别: char*是一个指向字符的指针,是一个内置类型。可以指向一个字符,也可以表示字符数组的首地址(首字符的地址)。我们更多的时候是用的它的第二的功能,来表示一个字符串,功能与字符串数组char ch[n]一样,表示字符串时,最后
Edit & run on cpp.sh this isn't really complete and probably has errors but i don't have a compiler to check. You might not need to use .c_str() becuase im pretty sure you can access the individual elements of a string simply by using an index. if this isnt the answer you were...
Edit & run on cpp.sh Apr 7, 2010 at 6:09pm dasman (9) Umm. what I want to do is create a char array of the interger split into highbyte and lowbyte. I want to send the integer over a serial com port which only receives 8 bytes at a time. and by the way the device im...
