Write a Program in C That Cube a Variable Using Pass-by-Reference With a Pointer Argument

// Cube a variable using pass-by-reference with a pointer argument.

#include <stdio.h>

void cubeByReference( int *nPtr ); // function prototype

int main( void )

{

   int number = 5; // initialize number

   printf( "The original value of number is %d", number );

 

   // pass address of number to cubeByReference

   cubeByReference( &number );

   printf( "\nThe new value of number is %d\n", number );

} // end main

// calculate cube of *nPtr; actually modifies number in main

void cubeByReference( int *nPtr )                              

{                                                              

   *nPtr = *nPtr * *nPtr * *nPtr; // cube *nPtr            

} // end function cubeByReference
