Q. Program to replace lower-case characters with upper-case and vice versa.

Here, our task is to replace all the lower-case characters in the string to upper-case and upper-case characters to lower-case. For this purpose, we need to traverse the string and check for each character. If the character is a lower-case character, make it upper-case by using the language-specific built-in method or add 32 to the lower-case character in C to change the ASCII value of the character.

Algorithm

  1. Define a string and traverse through it.
  2. If the lower-case character is encountered then convert them in upper case character using built-in function.
  3. If the upper-case character is encountered then convert them in upper case character using built-in function.
  4. If it's a character other than upper-case or lower-case alphabet take the character as it is.

Solution

Python

Output:

String after case conversion : gREAT pOWER

C

Output:

String after case conversion : gREAT pOWER

JAVA

Output:

String after case conversion : gREAT pOWER

C#

Output:

String after case conversion : gREAT pOWER

PHP

Output:

String after case conversion : gREAT pOWER
