Question 3.

For each case, write a for statement that prints the sequences of its values:

a) 24, 12, 6, 3

b) 3, 8, 13, 18, 23

c) 20, 14, 8, 2, -4, -10

d) 3, 6, 9, 12, 15, 18

Question 4.

What does the following program print?

#include

int main(void)

{

unsigned int x = 1;

unsigned int total = 0;

unsigned int y;

whil (x <= 10) {

y= x * x;

printf("%d ", y);

total += y;

++x;

} //end while

printf("Total is %d ", total);

} //end main

Question 5.

What does the following program print? How many inputs will be asked inside the loop from the user before exiting from the loop?

float price;

float total = 0;

int counter = 5;

do {

printf("Enter the iten price: ");

scanf("%f", &price);

total += price;

} while (counter --);

printf("Total = %8.2f", total);

Question 6.

What does the following program print? By assuming that the user enters 4 for x and 6 for y, show the output of this program.

#include

int main(void)

{

unsigned int x;

unsigned int y;

//prompt user for input

printf("%s", "Enter two unsigned integers in the range 1-20:");

scanf("%u%u", &x, &y); //read values for x and y

for (unsigned int i = 1; i <= y; ++i) { //count from 1 to y

for (unsigned int j = 1; j <= x; ++j) { //count from 1 to x

printf("%s", "@");

}

puts (""); //begin new line

}

}
