When you want to left or right shift some bits...or splice some addresses together like below..So when would you need this skill? Hardware programming comes to mind..
unsigned long two = 3345;
int main(int argc, char**argv)
unsigned long one = 1234;
void *addr = (void*)NULL;
fprintf(stdout, "one addr->%p\n", (void*)&one);
fprintf(stdout, "two addr->%p\n", (void*)&two);
/*splice the first 12 bits of two onto the first 12 bits of one*/
/*and save the result in addr*/
addr = (void*)(((unsigned long)&one>>12<<12) + ((unsigned long)&two<<52>>52));
fprintf(stdout, "result addr->%p\n", addr);
Write a C program that should create a 10 element array of random integers (0 to 9). The program should total all of the numbers in the odd positions of the array and compare them with the total of the numbers in the even positions of the array and indicate ...
I have a 2d matrix with dimension (3, n) called A, I want to calculate the normalization and cross product of two arrays (b,z) (see the code please) for each column (for the first column, then the second one and so on).
the function that I created to find the ...
