- The break statement has the following two usages in C −. When the break statement is encountered inside a loop, the loop is immediately terminated and program control resumes at the next statement following the loop. It can be used to terminate a case in the switch statement (covered in the next chapter). If you are using nested loops (i.e., one loop inside another loop), the break.
Caesar Cipher in C and C Encryption & Decryption Get program for caesar cipher in C and C for encryption and decryption. What is Caesar Cipher? It is one of the simplest encryption technique in which each character in plain text is replaced by a character some fixed number of positions down to it.

Defined in header <cctype> |
Checks if the given character is one of the 10 decimal digits: 0123456789.
The behavior is undefined if the value of ch is not representable as unsignedchar and is not equal to EOF.

[edit]Parameters
| ch | - | character to classify |
[edit]Return value
Non-zero value if the character is a numeric character, zero otherwise.

[edit]Notes
isdigit and isxdigit are the only standard narrow character classification functions that are not affected by the currently installed C locale. although some implementations (e.g. Microsoft in 1252 codepage) may classify additional single-byte characters as digits.
Like all other functions from <cctype>, the behavior of std::isdigit is undefined if the argument's value is neither representable as unsignedchar nor equal to EOF. To use these functions safely with plain chars (or signedchars), the argument should first be converted to unsignedchar:

Similarly, they should not be directly used with standard algorithms when the iterator's value type is char or signedchar. Instead, convert the value to unsignedchar first:
