C Programming: Simulate Program to Calculate xxx(17)

Click For Summary
SUMMARY

The forum discussion centers on a C programming simulation to calculate the number of times an integer can be divided by 2 until it is less than 2. The provided code defines a function `xxx(int n)` that counts the divisions, specifically for the input `xxx(17)`, which returns 4. The calculations show the progression of `n` from 17 to 1, confirming the correctness of the implementation. The output of the program is verified as accurate, printing "xxx(17)=4".

Homework Statement



Simulate the following program

#include <stdio.h>

int xxx (int n)
{
int count;

count = 0;

while ( n >=2)
{
n = n/2;
++count;
}

return count;
}

main()
{
printf( "xxx(17)=%d\n", xxx(17) );
}
