![]() ![]() As we can see in our output, it has not copied the whole phrase because we gave it the length of Y which was just 5 so it only copied 5 characters from the string. Our code will give the following output once it is executed. Using the printf() statement, we will print the copied array as output where %s is used to print the string from the first character to the null “\0” character and “y” is the resulting array that has to be printed. We have given the length of the Y variable as the third parameter so that it copies the same number of characters as that of the length of Y. Our main objective is to copy the string value which we have assigned to our source array “x” into our destination array “y”. This function has three parameters: source, destination, and length. In the above code, Y is our destination character string which we discussed earlier in the introduction. In strncpy, we passed both arrays destination as well as the source array along with the size to which the string is copied. We have stored String “Hello World” in our X variable which is our source variable.Īfter declaring our character arrays, we will call our strncpy function to copy our desired string to the other. In this example, we have declared two-character arrays that are X and Y using an array of size 20 for “x” and 5 for “Y”. We can also pass NULL to the source parameter. Then, give the size of our destination variable so that the function copies the same number of characters from our string x. ![]() In this function, we store a string in our source parameter and copy it to any destination represented as “dest”. The second parameter cannot be modified which is why it is constant. The second parameter “ const char*src” is a standard of C that specifies that the src is a character pointer, and in the third parameter we give the size to our function to define how many characters of the string to copy. In the syntax above, “char*dest denotes the destination to which the string is to be stored. The syntax to call strncpy() function is: In case the length of the string (from which the part of the string will be copied is less than the string to which the string will be copied), then it will not copy the complete string value to the destination string. Whereas, string_b is the one that will be used to fetch the first 6 characters of the string or the string from which the first 6 characters are to be copied. String_a is the string to which the content of the string is copied. Strncpy ( string_a, string_b, 6) will copy the first 6 characters of string “string_b” to the string “string_a”. Strncpy is responsible for copying a chunk of one string’s content into another. It is a crucial function that is offered by the C Language’s C String Library. Strncpy is also known as String Copy Function. ![]()
