Let us C Solutions | C Programming | How to Append, Concatenate, Copy, Print Strings in C Language

This video from the series Let Us C Solution Chapter 15 by TVP (Techvideopedia) discusses how to Append, Concatenate, Copy, and Print Strings in C.

In C, strings are represented as character arrays. A string is terminated by a null character ('\0').

To append a string to another string, you can use the strcat() function. The strcat() function takes two strings as its arguments and appends the second string to the end of the first string.

To copy some characters of a string to another string, you can use the strncpy() function. The strncpy() function copies the first n characters of the first string to the second string.

To print a string, you can use the puts() function. The puts() function prints the contents of the string to the standard output stream.

The puts, strncat, strcpy, and strncpy functions are all string-handling functions in the C programming language.
- puts prints a string to the standard output stream.
- strncat concatenates (appends) a specified number of characters from a source string to the end of a destination string.
- strcpy copies a string from one location to another.
- strncpy copies a specified number of characters from one string to another.

The main difference between strcpy and strncpy is that strcpy copies the entire source string to the destination string, while strncpy only copies the first n characters of the source string to the destination string.
