Adding strings is a common operation in C# and .NET. The String class provides several ways to add, insert, and merge strings including + operator, String.Concate (), String.Join (), String.Format (), StringBuilder.Append (), and String Interpolation.

What is string in C?
In C programming, a string is a sequence of characters terminated with a null character 0. For example:
How many characters can be in a name string?
The sizeof (name) results to 30. Hence, we can take a maximum of 30 characters as input which is the size of the name string.
Can string be passed to a function?
Strings can be passed to a function in a similar way as arrays. Learn more about passing arrays to a function.
Can you use pointers to manipulate strings?
Strings and Pointers. Similar like arrays, string names are "decayed" to pointers. Hence, you can use pointers to manipulate elements of the string. We recommended you to check C Arrays and Pointers before you check this example.
What is the difference between a string and a character array?
Strings are defined as an array of characters. The difference between a character array and a string is the string is terminated with a special character ‘0’.
Can you pass strings to function?
Passing strings to function: As strings are character arrays, so we can pass strings to function in a same way we pass an array to a function. Below is a sample program to do this:
Does C have a data type?
The C language does not provide an inbuilt data type for strings but it has an access specifier “ %s ” which can be used to directly print and read strings. You can see in the above program that string can also be read using a single scanf statement.
Can you read a string using a single scanf?
You can see in the above program that string can also be read using a single scanf statement. Also, you might be thinking that why we have not used the ‘&’ sign with string name ‘str’ in scanf statement! To understand this you will have to recall your knowledge of scanf. We know that the ‘&’ sign is used to provide the address of the variable to the scanf () function to store the value read in memory. As str [] is a character array so using str without braces ‘ [‘ and ‘]’ will give the base address of this string. That’s why we have not used ‘&’ in this case as we are already providing the base address of the string to scanf.

Can you read strings in C?
Strings are not always simply initialized or read. There will be times that the programmer will need to manipulate the value of the string according to the problem being solved. String manipulation can actually be done manually. However, this is very tedious work for the programmer. And because this task is very common to many C programs, a library has been created to make string handling more convenient and efficient.
Is there a string data type in C?
There really isn’t a string data type in C. Instead, the primitive data type char is used in arrays. Let’s say you have a string “sample” which has 6 characters. In C, it would simply be an array containing the characters, ‘s’, ‘a’, ‘m’, ‘p’, ‘l’, ‘e’.
