C++ -Strings

Strings

We will show just one small part of string, and with more details in rate number 2 in Microsam Academy. Exist difference how is the string defined in C and in C++.

In C the string is presented like rank of characters, which finished with “ \0 ”.

#include <iostream> using namespace std; int main() {                 char str[80];                 cout<<"Enter a string: ";                 cin>>str;                 cout<<"Here is your string: ";                 cout<<str<<endl;                 return 0; }

The program reads string of keyboard. But? Did you try to insert string joined of few words? What happens then? For example, I insert CODE THIS PC and how result I get CODE???

The cause of is that the operator for inserting  >>  stops with reading of keyboard when it comes on first gap place. One manner for resolving this nearly hard problem is to use one function of C++ library:

gets(array-name);

Is defined in library ( cstdio ). This function reads from the keyboard while you press ENTER.

#include <iostream> #include <cstdio> using namespace std; int main() {                 char str[80];                 cout<<"Enter a string: ";                 gets(str);                 cout<<"Here is your string: ";                 cout<<str<<endl;                 return 0; }

Exist few functions for manipulation with strings, but I won’t retain on them, I can just mention them:

strcpy(), strcat(), strlen(), strcmp()
