C + + input string with spaces

Law One:

#include <iostream> #include <string>using namespace std;void main () {    char test[100];//define long enough array space    for (int i=0;i<100;i++) test[i]= ' + ';    Cin.getline (test,100); Entire line read (including spaces)    cout<<test<<endl;    }

Law II:

#include <iostream> #include <string>using namespace Std;int main () {cout << "length of input string:" << Endl; int num;  You want to enter the length of the string cin >> num; GETC (stdin);  Remove the newline character of input num char * p = new char [num + 1];  Dynamic request you want to enter the length of the string memset (p, 0, num+1);   The requested space is initialized to 0 gets (p);  * (p+num) = ' + ';  End With ' cout ' << p << Endl; Delete[] p;  Release the memory system ("pause"); return 0;}
