program to get greatest number between two numbers

-------------------------------------------------------

// program to get greatest number between two numbers
#include<stdio.h>                      //header file
void greater();                          // function prototype/declaration with return type zero.
int main()                              //main function
{
greater();                                     // function calling.
return 0;                                       //returns 0 value
}
void greater()                              // function body line ; also called function definition
{
 float number1,number2;                    // variable declaration
printf("enter two numbers\n");           // displays message to input data
scanf("%f%f",&number1,&number2);        // gets data from user.
if(number1>number2)                     //condition testing
{
printf("%f is greater\n",number1);    // displays output
}
else
{
    printf("%f is greater\n",number2);    // displays output if the condition did not satisfy
}
}

/* here we have used top down approach. i.e calling from top and writing its body line down.
 we can also reverse the process.*/
