Function Exercise Write a program named order3.c with a function tripleorder (with void return-type which sorts the values of three integer variables (a, b, and c) into ascending order. The parameters to the function must be three pointers to these three variables. After the function returns the values in the variables should now be sorted from smallest to largest in the order that the variables were passed to the function. This means that the variable of the first pointer will hold the smallest value, and that the variable of the third pointer will hold the largest after the function is called. The main method should ask the user for three numbers, call this function, and print out the three numbers from smallest to largest (on one line with one space between each number) regardless of the order of the numbers entered by the user. To make this precise: If the variables to hold the users three numbers are, in order a, b, and c then use printf("%d %d %d\n", a, b, c); to print out the values in those variables.
