Answer:

This is what the code should do:

“Lift off in T minus

5

4

3

2

1

Blast-off!”

When I run it, it just keeps printing ''Sum = 5'' forever.

Explanation:

Code:

int main(void) {

int sum = 5;  

int i;      

printf("Lift off in T minus\n");

for (i = 0; i < 5; i=i+i) {

   sum = sum - i;  

   printf("sum = %d\n",sum);  

}  

printf("Blast-off",sum);  

return 0;

What is output by the following program? int i = 7; while (i&gt;=2){System.out.print (i +""); if ((i%3) == 0){ i +2; } else { i/
stiks02 [169]

Answer:

The correct answer to this question is: "this program give an error".

int i = 7; //declare a variable(i) and assign value.

while (i>=2) //use loop and check condition.i greater then equal to 2.

{

System.out.print (i +""); //print value of i.

if ((i%3) == 0) //hold remainder

{

i +2; //error.

}

else

{

i/=2; //hold Quotient

}

}

Explanation:

In the above program, there is an error in the if block because it is not the correct way to declare. To use the variable from the correct output we use a variable like this.

Example

int i = 7;

//declare a variable(i) and assign value.

while (i>=2)

//use loop and check condition.i greater then equal to 2.

{

System.out.print (i +""); //print value of i.

if ((i%3) == 0) //hold remainder

{

i =i+2;

}

else

{

i/=2; //hold Quotient

}

}

Output: 732

Given the function definition
kirza4 [7]

output of the following code fragment that invokes Twist is:

1 14 3

Explanation:

In the function Twist(),two parameters are passed. First is passed by value and second is passed by reference. If a variable is passed by value then any change made by the function will not affect the original value of that variable but when a variable is passed by reference then any change made by the function will change the original value of that variable. When Twist() function invokes with a=3 and b=2 then value of c=3+2 i.e c=5, a=3*3 i.e. a=9 (value of "a" was 3 earlier) and and b=c+a i.e b=5+9. Here only "b"is passed by reference for variable "s" then any change in it's value will be reflected in the "s". That will update the value of "s" to 14.

The area of a rectangle is the rectangle's length times its width.
aliya0001 [1]

Answer:

Following are program to this question:

#include <iostream> //defining header file  

using namespace std;  

int main() //defining main method

{

   double len1,len2,wid1,wid2,area1,area2; //defining double variable

   cout << "Enter first rectangle length: "; //print message

   cin >> len1;//input first rectangle length value

   cout << "Enter first rectangle width: ";//print message

   cin >> wid1; //input first rectangle width value

   area1 = len1*wid1; //calculate area and holds its value  

   cout << "Enter second rectangle length: ";//print message

   cin >> len2; //input second rectangle length value

   cout << "Enter second rectangle width: ";//print message

   cin >> wid2; //input second rectangle width value

   area2 = len2*wid2; //calculate area and holds its value  

   if(area1 > area2) //check condition area1 value is greater then area2

   {

    cout << "First rectangle area value is greater";//print message

   }

   else if(area2 > area1)//check condition area2 value is greater then area1

   {

       cout << "Second rectangle area value is greater";//print message

   }

   else //else block

   {

       cout << "both rectangle area is same";//print message

   }

   return 0;

}

Output:

Enter first rectangle length: 3

Enter first rectangle width: 5

Enter second rectangle length: 5

Enter second rectangle width: 3

both rectangle area is same

Explanation:

The description of the above program can be described as follows:

  • In the given code, the double variable is declared, which is "len1, len2, wid1, wid2, area1, and area2". In the next line, a message is a print, that accepts "len1 and wid1" value in the next line, the area variable is used that calculates area1.
  • In the next step, the "len2 and wid2"  variable is used, that accepts values and calculates its area, and in the next line, the conditional statement is used that checks its value.
  • In the if the block it uses both area1 and area2 value, that checks area1 is greater then area2, it is will print first rectangle area is greater.  
  • Otherwise, it will go to else if block, that checks area2 is greater then area1, it is will print second rectangle area is greater.  In the else section, it will print both equal areas.
