Thread: multiplying functions

hi i have written a code with multiple functions and i was wondering how i could multiply these functions together. a value is given to the functions from user input as seen below.

Code:

int main()
{
printf("-- Wind turbine power calculator -- \n");


getType();


getDiameter();


getAltitude();


getVelocity();


getPerformance();


getGenerator();


getGearbox();






return 0;
}

this is my main function in my code and i need to find this equation power = type x altitude x velocity x performance x generator x gearbox i was wondering how i could write a code that would perform this in order to calculate the power. the functions are written in this form

Code:

double getAltitude()
{
double a;


printf("\nEnter altitude (m):");
scanf("%lf", &a);


if (a > 9000)
{
printf("Invalid input! Altitude must be between 0 and 9000m");
return getAltitude();
}
else if ( a < 0 )
{
printf("Invalid input! Altitude must be between 0 and 9000m");
return getAltitude();
}
}

if this is not possible and i need to write the code in a different manner please let me know or if you have a solution then cheers.

Sorry, but a one page VERY brief tutorial does NOT equal a good book on The C Programming Language.

This site does have a list of Programming books, but the list is in serious need of an update. Some of the books listed have more current editions.

It might be enough for the OP to move forward with...
