This code segment first accepts a range of values in variables m and n, both of type int. The variable num, also of type int, is used as the loop variable. It assumes values from m to n. For each value of loop variable num, the printf statement within the for loop is executed.

switch statement is generally best to use when you have more than two conditional expressions based on

a single variable of numeric type. For instance, rather than the code

C program to encrypt text using one of the simplest ciphers known as the "Caesar cipher." In this encryption scheme, we shift all characters by a given offset. For example, if we use an offset of 4, every occurrence of 'A' will be replaced by 'E', every occurrence of 'B' will be replaced by 'F', and so forth. The encrypted text can be decrypted by using the reverse process if know the offset used for the encryption.

No, but it is not a bad idea to put default statements in switch statements for error- or logic-checking

purposes. For instance, the following switch statement is perfectly normal:

Both the switch and if-else-if statements enable us to select one of several alternative statements for execution. However, they differ in several aspects:

The C language allows nested if statements in which the if block and/or else block of an if statement contains if or if-else statements. The inner if statement(s) may in turn contain other if statements and so on.
