#include ... void sig_handler(){ static int i = 1; printf("Beep\n"); alarm(i); ++i; } int main(){ struct sigaction sa; sa.sa_fla

gs = 0; sa.sa_handler = sig_handler; if(sigaction(SIGALRM, &sa, NULL) != 0){ printf("Failed to bind handler.\n"); exit(1); } printf("Going into an infinite loop.\n"); alarm(1); while(1); return 0; }
Suppose the above program is run for 7.5 seconds after it prints "Going into an infinite loop". The program is run multiple times where the "system load" from other processes sharing the cpu will vary from none to many other processes. Which best characterizes how many times "Beep" is printed?

Answer:

Explained below

Explanation:

After the compiling the program it prints "Going to infinite loop" after that i started the timer till 4.5 sec. The program prints more than 4 beeps nearly 6-7 beep messages were printed.

The number "Beep" would always be strictly greater than 4.

Hence, if the above program is run for 7.5 seconds after it prints "Going in an infinite loop", it will print Beep for about 9-10 times. Hence, the number will always be greater than 7

2. Write a program that initializes an array of characters with the phrase, "Take me to Clearwater Beach!". Using pointers, scan
navik [9.2K]

Answer:

Written in C++

#include<iostream>

using namespace std;

int main() {

char myword[] = {'T','a','k','e',' ','m','e',' ','t','o',' ','C','l','e','a','r','w','a','t','e','r',' ','B','e','a','c','h','!', '\0'};

for (char *i = myword; *i != '\0'; ++i){

if( *i >= 'a' && *i <= 'z'){

           *i -= 'a' - 'A';    

       }

   }

   cout<<myword;

   return 0;

}

Explanation:

This line initializes the string to a char array

char myword[] = {'T','a','k','e',' ','m','e',' ','t','o',' ','C','l','e','a','r','w','a','t','e','r',' ','B','e','a','c','h','!', '\0'};

This iterates through the char array

for (char *i = myword; *i != '\0'; ++i){

This checks for uppercase or lowercase

if( *i >= 'a' && *i <= 'z'){

This converts to lowercase

           *i -= 'a' - 'A';

       }

   }

This prints the new string in all uppercase

   cout<<myword;

How I to turn this ''loop while'' in ''loop for''? var i = 0; while (i &lt; 20) { var lineY = 20 + (i * 20); line(0, lineY, 400,
Fudgin [204]

Answer:

for(i = 0; i<20;i++){

lineY = 20 + (i * 20);

line(0, lineY, 400, lineY) }

Explanation:

First declare and initialize the variable i. You have not specified the data type of i so if the data type of i is integer i.e. int then you should declare i variable in the for loop as for(int i = 0; i<20;i++)

So the given while loop has a variable i which is initialized to 0. Then while(i<20) means that while loop executes until the value of i exceeds 20. If this while condition is true then the two statements inside its body will execute. The two statements are: lineY = 20 + (i * 20);

line(0, lineY, 400, lineY);

The value of i ins incremented after each iteration i.e. i++

So while loop has the following syntax"

1) initialization;  ---->  i = 0

2) while(condition) {  ----> i<20

3) loop body ----->  lineY = 20 + (i * 20); line(0, lineY, 400, lineY);

4) increment or decrement loop variable  } ----> i++

For loop has the following syntax:

for( initialization of loop variable ; condition; decrement/increment loop variable)  {

loop body }

Here:

initialization  ---->  i = 0

condition        ----> i<20

loop body     -----> lineY = 20 + (i * 20); line(0, lineY, 400, lineY);

increment or decrement loop variable  ---->  i++
