My question is c programming. Write a complete program (main and a helper function), which calls a function in its main.   Your function takes a string of letters and return the same string with lowercase "r" changed into an uppercase "R" and any combination of "sto" changed into "STO" (do not change s, t, and o alone

Write C++ funtion GCD(int a, int b) having single line of code only in the function. Don't answer if you can't do it in one line else I will downvote.

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.

Modify the piglatin program. Pig Latin is a made-up “language” formed from English by transferring the initial consonant or consonant cluster of each word to the end of the word and adding a vocalic syllable (‘ay) so “chicken soup” would be translated to “ickenchay oupsay.” Consider what the piglatin program does with words that begin with the letter “y” such as “yellow.”  Modify the the function piglatin() to also work correctly for these inputs.  Do not modify firstvowelindex(). (both before and after) Enter a word: magenta In Pig Latin, that word is:  agentamay   (before) Enter a word: yellow In Pig Latin, that word is:  yellowyay   (after) Enter a word: yellow In Pig Latin, that word is:  ellowyay
