I am having an issue with the following program. This is just a simple program that calculates the surface area/volume of a cylinder. For some reason this executes JUST fine in CodeBlocks. Everything works exactly as it should and I get the correct values.
However, when I try to run it in the IDE that my professor forces us to use I always get 0 for values. If I change all the variables to int and use %d it will compile fine in both, but I lose accuracy. Double is required. Is %lf the correct scanf() function to use for doubles? I have tried many different things and I cannot get it to work properly in the IDE for my class.
Here is the following code:
Code:#include <stdio.h>
#define PI 3.141593
double computation(double l, double r)
{
if (2*r >= l)
{
printf("These dimensions do not define a valid tank");
}
else
{
double volCYL = (PI * r * r * l);
double volSPH = (4.0/3.0 * PI * r * r * r);
double surfCYL = (2 * PI * r * l);
double surfSPH = (4 * PI * r * r);
printf("\n");
printf("A cylindrical tank of length %.3lf and radius %.3lf with inverted spherical\n", l,r);
printf("caps has\n");
printf("volume: %.3lf\n", volCYL-volSPH);
printf("and\n");
printf("surface area: %.3lf\n", surfCYL+surfSPH);
printf("\n");
printf("Program Termination.\n");
}
return 0;
}
double length = 0;
double radius = 0;
int main()
{
printf("ACME Truck Company\n");
printf("\n");
printf("This program will calculate the volume and surface area of the x-11\n");
printf("cylindrical tank\n");
printf("Enter the length of the tank (feet)");
scanf("%lf",&length);
while (length < 10 || length > 20)
{
printf("Invalid value\n");
printf("Please enter a value between 10 and 20:");
scanf("%lf", &length);
getchar();
}
printf("Enter the radius of the tank (feet)");
scanf("%lf", &radius);
while (radius < 3 || radius > 6)
{
printf("Invalid value\n");
printf("Please enter a value between 3 and 6:");
scanf("%lf", &radius);
getchar();
}
computation(length,radius);
return 0;
}
Any help would be much appreciated!
