For each of the 4 functions below, Re-code each one to make it programmer friendly, using standard coding conventions, and documentation. Document each function with: a description of what it does (one sentence) and how it works (no more than 3 sentences). Also, provide a precondition: and a postcondition: statement. (See example for the setTime function below.) 1. 2. setTime(int hours, int minutes, int seconds); //Function to set the time //The time is set according to the parameters //Precondition: All parameters are valid numbers, within the range of clock hours (1 - 12), minutes (0 - 59), and seconds (0-59). //Postcondition: The clockType instance stores the hours, minutes and seconds. // 4. If any of the parameters are not valid the time values will be set to zeros. int 1 (double x) {return (int) (x + 0.5); } ; int 2 (char* s) {char*t = s; while (*t != '\0') {t++; } return t-s; }; 3. long 3 (int x, int y) {long n=1; for (int i = 0; i < y;i++) {n*=x; } return n; }; 4 (char* s) {int r=0; for (int i=0, n=strlen(s) ;i
