This function appends not more than n characters from the string pointed to by src to the end of the string pointed to by dest plus a terminating Null-character.

What is a string handling function?

C programming language provides a set of pre-defined functions called string handling functions to work with string values. The string handling functions are defined in a header file called string.

How do you pass a string to a function?

In C, if you need to amend a string in a called function, pass a pointer to the first char in the string as an argument to the function. If you have allocated storage for the string outside the function, which you cannot exceed within the function, it’s probably a good idea to pass in the size.

What is the use of const char ch in C++?

As the name suggests, this function is used to return the characters of the string in the lower case. This function is used to return the size of the string i.e. the characters the string is capable to hold at a stretch. This function searches for the character in a particular string. const char ch = ‘.’;

What is string handling in C programming?

Handling strings mean that your programming language should be efficient enough to modify the string that you have and perform the required changes.
