Identify and explain the mode of data transfer in which CPU continuously monitor the status register for transferring the data. Support your answer with a neat and clean diagram.
Have a look at the following piece of code and state and explain the output.
#include <stdio.h>
int main() {
// your code goes here
char *s = "abcdef";
*(s + 2) = '\0';
printf("%d", s);
return 0;
}
Andrew likes the topic of strings a lot and tries to solve as many problems as he could on this topic. He came
across a problem in which he was given two numbers in the form of strings and he was asked to subtract the second
number from the first and print the answer. The strings will contain numbers only.
Sample Run:
Input:
222
122
Output:
100
Andrew practices programming a lot and recently he came across the topic of pointers. He wondered if he could
use pointers to print all prime numbers from an array? Could you help him by writing a program which takes input
in an array and uses a pointer to find and print all the prime numbers from the array.
Sample Run:
Input:
1 2 3 4 5
Output:
2 3 5
Analogue optical fiber communications link have OSNR = 10 dBm and the signal
to noise ratio (SNR) = -200dBm. What is the indication about this system? Suggest a
solution about this problem.
d2C/ dy2= [dC2/dȳ2. (1/√(y)) + dC/dȳ .d/dȳ (1/√(y))]
please try to bring the equation a modified Bessel Equation of appropriate order. Identify the the order and write down the analytical solution for the concentration distribution C= f (ȳ) and thus C= f(z) using modified Bessel Functions.
The values are given if you need it.
