Question 1 (2.0 points): Give a following program, please perform:

a) Draw a flowchart?

b) Show results on the screen after performing the program?

# #include <stdio.h>

int main (void)

{

int a = 10, b = 5, c = 17, d=2;

if ((a > b) && (b<c))

{

a = c + 2;

b += d - 2;

c = a / b;

d = ++b - c;

}

else

{

b -= ++a;

d = c - b;

}

printf("a:%d\n", a);

printf("b:%d\n", b);

printf("c:%d\n", c);

printf("d:%d\n", d);

return 0;

}

a) a flowchart

b) Results on the screen

Question 2 (2.0 points): Draw flowchart and write a program that sums a sequence of integers

Assume that the first integer read with scanf specifies the number of values remaining to be entered Your program should read only one value each time scanf is executed For example, a typical input sequence might be 5 100 200 300 400 500 where the 5 indicates that the subsequent five values are

to be summed

Question 3 (1.5 points): Show results on the screen after performing a following program: # #include <stdio.h> void main() { int a[6] = { -2, 0, 2, 3, 4, 5 }; int *p1 = &a[1]; int *p2 = &a[2]; *(p1 - 1) = *p2 + 2; *p1 = *p2 - 4; *(p2 + 1) = a[4] + a[5]; p2++; *(p2 - 1) = *(p1 - 1) + *p1 + 1; *(p2 + 1) = *p1 + 2; *(p2 + 2) = 2 * *p1 + 5; printf("%d, %d, %d, %d, %d, %d", a[0], a[1], a[2], a[3], a[4], a[5]); }

Question 4 (3.0 points):

- Edit bugs of a following program (2.0 points):

The program

#include <stdio.h>

#include <conio.h>

#include <malloc.h>

void Function1(int *x, int y)

int Function2(int *x, int y)

int Function3(int *x, int y);

void main()

{

int *array, n, i;

scanf("%d", &n);

array = (int *)malloc(n,sizeof(int));

if (array != NULL)

{

Function1(array, n)

if (Function3(array, n) == 1)

if (Function2(array, n) == 1)

for (i = 0; i < n; i++)

if (*(array + i) % 2 == 1)

printf(" %d ", *(array + i));

}

}

void Function1(int *x, int y)

{

int i;

for (i = 0; i < y; i++)

scanf("%d", *(x + i));

}

int Function2(int x, int y)

{

int i;

for (i = 0; i < y, i++)

{

if (*(x + i) % 2 == 1)

return 1;

}

return 0;

Edit bugs

}

int Function3(int *x, int y)

{

int i;

for (i = 0; i < y - 1; i++)

{

if (*(x + i) > (x + i + 1))

return 0;

}

return 1;

}

- Assume that the above program is edited correctly When five numbers 4, 5, 6, 7, 8 are inputted from the screen, what are results showed on the screen next (1.0 point)?

Question 5: (1.5 points) Write a complete program which executes functions as follows: a) Create a structure type, named SensorNode, to describe a Sensor Node The Sensor Node will collect temperatures and includes information as follows:  Node Code (named NodeCode): string format  Temperature value (named Temp): real number format b) Enter information including Node Code and Temperature value of 20 different Sensor Nodes c) Print all information of three Sensor Nodes on the screens which collect high temperature values 1st, 2nd and 3rd
