Engineering Computer Science C++ How to Program (Early Objects Version)

Program Plan: Include the required header files. Define the value of pi as 3.14159. Define a macro volSphere to calculate the volume of the sphere using r as a parameter and pi value. Define the “main()” function. Declare the variable str to store the string value we get from the keyboard. Call the macro volSphere to calculate the volume of the sphere. Program Description: This program uses the macro volSphere to calculate the volume of the sphere. Program: #include <iostream> usingnamespace std; #define pi 3.14159 /*macro for calculating volume*/ #define volSphere(r)((4.0/3)*pi*r*r*r) // Define main function intmain() { /*Declare the variable radii for radius value and volume to store calculated sphere value */ int radii; float volume; /*tabular format*/ cout<<"Radius_Value"<<"\t"<<" VOLUME_SPHERE"<<endl; for(radii=1;radii<=10;radii ++) { volume=volSphere(radii); cout<< radii <<"\t"<< volume <<endl; } return0; } Sample output: Radius_Value VOLUME_SPHERE 1 4.19 2 33.51 3 113.1 4 268.08 5 523.6 6 904.78 7 1436.76 8 2144.66 9 3053.63 10 4188.79
