Respuesta :
To write a program whose input is a character and a string, and whose output indicates the number of times the character appears in the string.
What is string?
A string in computer programming refers to a group of characters, either as a literal constant or as a kind of variable. The latter may be fixed in length or may permit its elements to be altered (after creation).
A string is typically regarded as a data type and is frequently implemented as an array data structure made up of bytes (or words) that uses character encoding to store a sequence of elements, typically characters. Additionally, the term "string" can refer to more general arrays or other sequence (or list) data types and structures.
A variable that is explicitly declared to be a string may either result in memory being statically allocated for a predetermined maximum length or, depending on the programming language and precise data type employed, the opposite.
