Programming with C Language
Using sub program
Function max & min

Sub program: a funtion that
returs the max number

/*
Using here a sub program along with the main program
*/

#include <stdio.h>
// The sub program: a funtion that returs the max number
//------------------------------------------------------


float max (float x, float y)
{
if (x > y)
return x ;
else
return y ;
}

This function sets and returns the largest value between two real numbers x and y

// The main program:
//------------------


int main()
{
float number1, number2 ;

// Read the two flots

printf("Enter two floats \n -> ");
scanf ("%f%f", &number1, &number2);

// Display the two floats:

printf("The entered read numbers are: \n number1 = %5.3f, " "number 2 = %12.3f\n", number1, number2);

// Use the function max to display the maximum value:

printf("The max value is : %1.7f\n",
max (number1, number2));

// The used format reads and write the floats in wathever
// columns, but with two decimal digits
return 0;
