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。
string-name.c_str(); Copy At first, we use c_str() method to get all the characters of the string along with a terminating null character. Further, we declare an empty array of type char to store the result i.e. result of the conversion of string to char array. Finally, we use...
