The following are some examples that use the string operations strcpy( ), strcat( ),
strlen( ), strcmp( ), strchr( ), and strstr( ).

strcpy( ) Chapter Four: Object oriented programming with C++

The following Program Example 4.36 shows the use of a string function for copy.

Program Example 4.36:

Using Strcpy( ) string function

Taking the string s1 and s2 in strcpy(s1,s2). This string function of C++ will copy
the string s2 into string s1.

#include <iostream>
#include <cstring>
using namespace std;
int main()
{
char string1[]=”Hujambo”;
char string2[]=”Mwananzengo”;
strcpy(string1, string2);
cout << “The result of strcpy is : “ <<string1 << ‘\n’;
}

Output: The value of string2 (Mwananzengo) will be copied to string1 (Hujambo)
and string2 value will display (Mwananzengo) as shown in Figure 4.67.

Figure 4.67: Output of string2

strcat( )
The following Program Example 4.37 shows the use of the string function for
concatenation.

Program Example 4.37:

Using strcat( ) string function

Taking the string s1 and s2 in strcat(s1,s2). This string function of C++ will
concatenate the string s2 at the end of string s1.
