Exercise#2: Pre-defined and User-defined functions Write the following functions: Function #1: 1) Name: Inputx 2) Parameters: no parameters 3) Job: Input a double variable and return its value Function #2: 1) Name: GetY 2) Parameters: double x 3) Job: calculate y using the formula below and return y. Function #3: 1) Name: OutputXY() 2) Parameters: double x, double y 3) Job: Output x and y as shown in the sample output. Limit the output of y to 5 decimal places. int main() ( Use the following main() to test your function. You only need to implement the three functions. If the function are Implemented correctly then you will get the correct output. double X, Y: y= X = InputX(): Y = GetY (X): -2x+cos (x) 5sin (2x) Output XX (X, Y); return 0; Sample input/output: Enter the value of x: 3.1 For 3.1 the value of y is 17.32865 Enter the value of x: 0.921 For 0.921 the value of y is -0.25678 Exercise#2: Pre-defined and User-defined functions Write the following functions: Function #1: 1) Name: Inputx 2) Parameters: no parameters 3) Job: Input a double variable and return its value Function #2: 1) Name: GetY 2) Parameters: double x 3) Job: calculate y using the formula below and return y.
