Function definition for “mul3div4()” function:
The implementation for “mul3div4()” function is given below:
//Header file
#include <stdio.h>
#include <assert.h>
#include <limits.h>
//Function definition for divide by power of "2"
int divide_power2(int x, int k)
{
//Determine negation value
int isNegation = x & INT_MIN;
//Check condition
(isNegation && (x = x + (1 << k) - 1));
//Returns value by using "x >> k" that is "x/(2^k)"
return x >> k;
}
//Function definition for mul3div4 function
int mul3div4(int x)
{
//Compute multiply "3"
int m3 = (x << 1) + x;
/* Returns the value of "3 * x/4" by calling function "divide_power2" */
return divide_power2(m3, 2);
}
//Main function
int main(int argc, char* argv[])
{
//Assign the value for "x"
int xValue = 0x87651234;
/* Call function "mul3div4" with checking "x * 3 / 4" value using assert function */
assert(mul3div4(xValue) == xValue * 3 / 4);
return 0;
}
The given code is used to compute the value of “
