11. Write a function in C++ language that takes string str and integers i,j as parameters and then reverse the substring of str from index i to index j. Given, i

My question is for C programming. Write a complete program by using four helper functions The whole requested parts should be written in one single program. For all the functions, use the same prototype. Do not hard code any value, all the values must be given by the user in the whole code. The first function is getting a string and prints the given string, use the same given prototype: void myname ( char firstlastname[ ]); when you test the program, you will call the function in the main, the input will be your name ( you will prompt the user) and the functions prints it completely. The second function which you will add to the program will take 3 integer values and return the average all the 3 integer values, use the same prototype which is given here: double ave ( int num1, int num2, int num3); Call the function in the main, ask the user for 3 values. Test case for 3 given values by the user: 3 5 2 The third function will accept an array of numbers and prints it in the reverse...

Write a C++ function to take a string s and index i as the parameters and remove the character at index i from the string s and return the modified string. The variable i will always be in the range 0 to s.length()-1.

: Implement a function void reverse( char* str) in C or C++ which reversesa null-terminated string.

Write a C++ function add_strings that takes two parameters of type string and returns the concatenation of the two parameters.
