Introduction
Char () and int () are two functions in C++ that are used to convert data types. Char () is used to convert an integer value to its corresponding character value, while int () is used to convert a character value to its corresponding integer value. These functions are useful when dealing with data types that are not compatible with each other, such as when a character needs to be converted to an integer or vice versa. They are also useful when dealing with user input, as they can be used to ensure that the data type of the input is correct.
Solution
Yes, char() and int() are functions in C++. They are used to convert a character or an integer to its corresponding ASCII value.
They’re not functions. They’re just alternate syntax for type-casting. char(x) is more-or-less equivalent to static_cast<char>(x).
In general, in C++, one should prefer the C++-specific constructs for casting objects (static_cast, dynamic_cast, const_cast, and reinterpret_cast), as those help ensure you don’t do anything dumb when casting objects. So in your code example, I’d recommend rewriting it as
result += static_cast<char>(static_cast<int>(text[i]+s-65)%26 +65);
But functionally, it’s all identical.

solved char () and int () are functions in c++? [duplicate]
The char() and int() functions are both used in the C++ programming language. The char() function is used to convert an integer value to a character value, while the int() function is used to convert a character value to an integer value. Both functions are useful when dealing with character data, as they allow for the conversion of data types.
The char() function takes an integer value as an argument and returns the corresponding character value. For example, if the argument is 65, the function will return the character ‘A’. Similarly, the int() function takes a character value as an argument and returns the corresponding integer value. For example, if the argument is ‘A’, the function will return the integer 65.
Both the char() and int() functions are useful when dealing with character data, as they allow for the conversion of data types. This can be useful when dealing with strings, as it allows for the manipulation of individual characters. Additionally, these functions can be used to convert between different character encodings, such as ASCII and Unicode.
In summary, the char() and int() functions are both used in the C++ programming language. The char() function is used to convert an integer value to a character value, while the int() function is used to convert a character value to an integer value. Both functions are useful when dealing with character data, as they allow for the conversion of data types.
