Write in C Language Description Please finish the function replace and function replaceAll. char *replace(char *source, char *pattern, char *replacement); char *replaceAll(char *source, char *pattern, char *replacement); Function replace will find the first appear pattern in source and replace it withreplacement. Function replaceAll will find all pattern in source and replace it with replacement.   function char *replace(char *source, char *pattern, char *replacement) { } char *replaceAll(char *source, char *pattern, char *replacement) { }

Build a database of predefined function presets.

Consider the function void modify(int & x) { x = 10; }Show how to call the modify function so that it sets the integer int i;to 10.

Call by value in programming means that a copy of variable value is pased from function calling part to function definition part. Call by reference means that an address of variables are passed from calling part to function definition.   arrow_forward Step 2 Call by reference is used to avoid extra memory usage because in call by reference same variables addresses are passed. Any changes made will reflect back. So it doesn't require extra variable to hold data. Call by value in programming is used where memory storage is not concern. Scenario in which actual value must not be disturbed then in these type of cases, call by value is used.  We can't use only one because user requirement changes. Sometimes user tella actual data should be preserved and he/she want any data processing, in such scenario programmers use call by value. Some users only want calculated result. In such cases, programmers use call by reference to preserve memory usage.  So it is totally dependent on user…

Explain how inline functions differ from normal functions when called in the background.

The input string is provided as a parameter to the compress_string function. The Challenge: You must build a reference to a function that accepts a single integer parameter and returns an array of pointers to functions that accept a single string input and return an integer.Whew! You have to read the specification at least three times before you realise you don't comprehend it.How do you handle something so complicated.

Local declarations are those that are kept in the memory of the computer; but, how exactly are they kept in memory? If reaching one's objective can be done without making use of local declarations, then doing so is a waste of time. Why bother using value parameters when you can just use references as your arguments in any function? How crucial are value parameters when it comes to the processing of programmed data?
