Implement function rotate that takes a string argument s and an integer argument n, and rotates the string s to the left by n times. For example, the code char s[] = "systems"; rotate(s, 3); will change s into "temssys",  while the code char t[] = "abcd"; rotate(t, 1); will change t into "bcda" void rotate(char *t, int f)

Define a function RemoveCommas() that takes a string parameter and returns a string. The returned string is the parameter with all of the commas removed. Ex: RemoveCommas("mouse,toy,fox,bear,pet") returns "mousetoyfoxbearpet" Recall string's size() returns the number of characters in a string. Ex: myString.size() string's at() returns a character at the specified position in the string. Ex: myString.at(3)   #include <iostream>#include <string>#include <cctype>using namespace std; /* Your code goes here */ int main() {   string input;   string output;    getline(cin, input);        output = RemoveCommas(input);      cout << output << endl;    return 0;}

Return Something to Me! Write a function that returns the string "something" joined with a space " " and the given argument a. Examples giveMeSomething("is better than nothing") → "something is better than nothing" giveMeSomething ("Bob Jane") → "something Bob Jane" - → "something something" giveMeSomething("something")
