char string1[]=”Hujambo”;
char string2[]=”Mwananzengo”;
strcat(string1, string2);
cout << “The result of strcat is : “ <<string1 << ‘\n’;
}

Output: The value of string2 (Mwananzengo) will be concatenated to string1
(Hujambo) and string2 value will be printed as shown in Figure 4.66.

strlen( )
The following Program Example 4.38 shows the use of the string function for
calculating length of a string.

Program Example 4.38:

Using strlen( ) string function

Taking the string s1 in strlen(s1), this string function of C++ will calculate and
return the length of string s1.

#include <iostream>
#include <cstring>
using namespace std;

int main()
{
char string1[]=”Mzalendo madhubuti wa nchi yake”;
cout << “The result of strlen is : “ <<strlen(string1)<< ‘\n’;

}
