Convert Character from Uppercase to Lowercase


Write a C++ Program to Convert a Character from Uppercase to Lowercase. Here’s simple C++ Program to Convert a Character from Uppercase to Lowercase in C++ Programming Language.


C++ Strings : 


String is a sequence of characters. char data type is used to represent one single character in C++. So if you want to use a string in your program then you can use an array of characters.

The declaration and definition of the string using an array of chars is similar to declaration and definition of an array of any other data type.

Any string ends with a terminating null character ‘\0’. An array definition in such a way should include null character ‘\0’ as the last element.

C++ provides following two types of string representations:

  • The C-style character string.
  • The string class type introduced with Standard C++.

The C-style character string originated within the C language and continues to be supported within C++. This string is actually a one-dimensional array of characters which is terminated by a null character ‘\0’. Thus a null-terminated string contains the characters that comprise the string followed by a null.

Write a full program that asks the user to enter a phrase and then a single letter. The program should then report how many times that letter occurred in the phrase, displaying the letter with double quotes around it. An example is shown below where the user searched for lower-case “g”. Enter phrase: I love programming languages! Enter letter: g The letter “g” occurred 4 times. Your program does not have to check upper versus lower case.
