C++ Program to Implement strncpy() Function

This is a C++ Program to Implement strncpy() Function.

The program takes a string and copies first ‘n’ characters into another string using the function strncpy().

1. The program takes a string.
2. The number of characters to copied is taken.
3. Using the string function strcpy(), first n characters are copied into another string.
4. The result is printed.
5. Exit.

Here is the source code of C++ Program to Implement strncpy() Function. The program output is shown below.

1. The user is asked to enter a string and stored in the character variable ‘str’.
2. Number of characters to be copied is asked to enter. It is stored in the variable ‘n’.
3. Using strncpy(), first ‘n’ characters from str are copied into a new string ‘cpy’.
4. The copied string is then printed.

Case 1 :
Enter a string : Hello
Enter number of strings to be copied : 4
Copied string : Hell
 
Case 2 :
Enter a string : 25 + 12 = 37
Enter number of strings to be copied : 7
Copied string : 25 + 12
 
Case 3 :
Enter a string : fresh&fresh
Enter number of strings to be copied : 5
Copied string : fresh
