If you are using String STL,i.e., #include <string>, the way to go would be : string str = "sentence"; length = str.length(); cout<<length; // Output - 8 But, if you are not using STL, and declaring string the traditional way, then the method would be : char str[ ] = ...

You need to return a string representing their multiplication. Note i2 = -1 according to the definition. Example 1: Input: “1+1i”, “1+1i” Output: “0+2i” Explanation: (1 + i) * (1 + i) = 1 + i2 + 2 * i = 2i, and you need convert it to the form of 0+2i....
string str = ""; str = ss.str(); int len = str.size(); int flag = 0; for(int i = 0 ; i < len; i++) { if(str[i] == str[len -1 -i]) ; else flag = 1; } if(flag == 1) rs = false; return rs; } };这个...

Validate if a given string is numeric. Some examples: "0" => true " 0.1 " => true "abc" => false "1 a" => false "2e10" => true Note: It is intended for the problem statement to be ambiguous. You should gather all requirements up front before implementing one. ...
