Complete the function main in file median.c to implement the computation of the median of a sequence of integers read from stdin. The program should use realloc to allow an arbitrary number of integers to be read into a dynamically allocated array. Every time realloc is called, let the new size of the array be twice the old size plus 1. Look at function readLongLine in the slides for Chapter 6 for an example of how to use realloc. The program should return -1 if anything other than an integer is read from stdin. A test script is provided in test_median.sh.
Note that median.c uses qsort from the standard library to sort the array of integers. We have not seen how to call qsort yet, so don't worry if it still looks mysterious. It involves passing a function pointer, which we shall cover shortly.
Here is the function
#include <stdio.h>
#include <stdlib.h> /* for realloc, free, and qsort */
/*
* Read integers from stdin until EOF. Then
* print the median of the numbers read.
*/
/*
* Print the median of a sequence of sorted integers.
*/
void printMedian(int const * numbers, int cnt) {
int i, halfWay;
double median;
/* debugging printout of sorted array */
for (i = 0; i < cnt; i++) {
printf("%d%c", numbers[i], i == cnt-1 ? '\n' : '
');
}
halfWay = cnt / 2;
if (halfWay * 2 == cnt) {
/* cnt is even: average two middle numbers
*/
median = 0.5 * (numbers[halfWay] +
numbers[halfWay-1]);
} else {
/* cnt is odd: take middle number */
median = numbers[halfWay];
}
printf("Median of %d integers: %g\n", cnt, median);
}
/* Integer comparison function for qsort. */
static int icompare(void const * x, void const * y) {
int ix = * (int const *) x;
int iy = * (int const *) y;
return ix - iy;
}
int main(void) {
/* Size of allocated array. */
size_t size = 0;
/* Number of ints stored in the array. Must be less
* than or equal to size at all times. */
size_t cnt = 0;
/* Pointer to dynamically allocated array. */
int * numbers = 0;
/* Variables used by scanf. */
int num, ret;
while ((ret = scanf("%d", &num)) != EOF) {
/* Your code here. */
}
if (!numbers) {
printf("Read no integers. Median
undefined.\n");
return -1;
}
/* Sort numbers in ascending order. */
qsort(numbers, cnt, sizeof(int), icompare);
printMedian(numbers, cnt);
free(numbers);
return 0;
}
How do I go about finishing this? This is in C language remember that.

A 6-pole and three-phase induction motor has synchronous speed of (1000) RPM.
a) Find the no-load and full-load operating speed of motor for the cases given,
1. 2.5Hz electrical frequency of rotor for no-load condition.
2. 6.3Hz electrical frequency of rotor for full-load condition.
b) Find the speed regulation of motor by using parameters found above.
c) Determine the electrical frequency of rotor under full-load condition so that speed regulation would be equal to 5%? (Electrical frequency of rotor for no-load condition is still 2.5Hz.)

What type Integrated Circuit do I need to light a certain amount of connected series or parallel LEDS depending on my voltage. So I have a system that harvest energy and charging a capacitor steadily to around 3V max and I want it to make it so as it's charging the LED lights up. Let say 0.5V LED1 light up and at max voltage all LED light up, so up to say 5 LEDS. Is this possible? if it is what type of IC can i use to do this?

Two design approaches sensitive photodetectors are: (i) using
photogenerated electron/hole pairs in the
base of a BJT; and (ii) using a reverse-biased pn junction
operating in the avalanche regime. In point
form, summarize the strengths, weaknesses and similarities of these
designs.

Sketch the equilibrium band structure of pnp bipolar junction
transistor (BJT). In point form, explain how
the application of a bias voltage at the “base” changes the band

used to turn this device “on” and “off”. (a well-labeled
equilibrium diagram will enable you to complete this without
any further band-structure diagrams)
