A string is nothing but an array of characters. The value of a string is determined by the terminating character. Its value is considered to be 0. As it is evident with the image uploaded above, we need to enter both the strings which we need to concatenate or link. Both the strings ...

Example 3: Creating a full path from directory and file names This example demonstrates using strcat() to form a file path by combining a directory name and a file name. Code: #include <stdio.h> #include <string.h> int main() { // Define a directory path and a file name char path...

我们已在第一章学习了用iostream标准库来读写内置类型的值,如intdouble等。同样地,也可以用iostream和string标准库,使用标准输入输出操作符来读写string对象: // Note: #include and using declarations must be added to compile this codeint main(){string s; // empty stringcin >> s; // read whitespace...
intmain() { std::strings=std::string("Concatenate")+ std::string(" string literals ")+ std::string("to std::string"); std::cout<<s<<std::endl; return0; } 下載運行代碼 輸出: Concatenate string literals to std::string 這就是在 C/C++ 中連接字符串文字的全部內容。
