Write a program "three.c" which contains a function (named "three") that takes two arguments: a pointer to an int and a pointer to a char. The function should return a float. This function should examine the value pointed at in the first argument. If the value is even, set the value pointed at by the second argument to be an 'E', if it is odd, set the second value to 'O'. Then return the integer pointed at by the first argument reduced by 1 as a float (you will need to cast the result). Finally, increment the first integer. Example Input: 7 Output: 806.0 Here's a copy of the starter code: #include // Define three here. int main(void) { int a; scanf("%d", &a); char b; float c = three(&a, &b); printf("%d %c %.lf", a, b, c); return 0; }
