This is your code.
lubasha [3.4K]

Answer:

35

Explanation:

We will be going inside B array, because he was in second place in array E,and will be the first element of array B, so it's 35

E can be understanded as:

E=[[21, 'dog', 'red'],[35, 'cat', 'blue'],[12, 'fish', 'green']], so, you can see array E as array of arrays or so-called two-dimensional array

2.8 Code Practice: Question 1
-BARSIC- [3]

Answer:

The program to this question can be given as:

Program:

#include <stdio.h> //define header file

int main() //define main method.

{

int a1,b1,c1; //define variable

printf("Enter three numbers:\n"); //message

scanf("%d",&a1); //input numbers.

scanf("%d",&b1);//input numbers.

scanf("%d",&c1);//input numbers.

if (a1>b1) //check condition

{

//check condition

if(a1>c1)//inner if block

{

printf("The largest number: %d", a1); //message

}

else  //inner else block

{

printf("The largest number: %d", c1);//message

}

}

else //else block

{

//check condition

if(b1>c1) //inner if block.

{

printf("The largest number: %d", b1);//message

}

else //else block

{

printf("The largest number: %d",c1);//message

}

}

return 0;  //return 0.

}

Output:

Enter three numbers:

22

44

11

The largest number: 44

Explanation:

The description of the above program can be given as:

  • In the C language program firstly we define the header file. Then we define the main function. In the main function, we define three variables that are "a1, b1 and c1". In this variable, we take input from the user.
  • Then we define the conditional statements. In the if block we check if the value of a1 is greater then the value of b1 if this condition is true so we use another condition that if the value of a1 is greater then the value of c1. so, it will print the largest value. If the above condition is not true then it will go to else section.
  • In the else part we check the condition that if the value of b1 is greater then the value of c1. if it is true it will print the largest number value.

Keep a log of the different types of communication activities in which you engage during the rest of the day. Categorize each ac
baherus [9]

There are 4 different types of communication and I can share my experience by helping you out to solve the assignment.

Explanation:

1. Verbal Communication:

  • Communication with voice
  • Provides active listening
  • Body language is equally important.

2. Non-Verbal:

  • Body language is the most important
  • Communicating without using the words

3. Visual communication:

  • Listening contents through photos and videos

4. Written communication:

  • Serves as record
  • Does not require tone

So in day today aspect we come across almost all type of communication. To answer the discussed question

1. Did the variety of communication surprised you?

I would say yes. I can say unknowingly I have experienced various types.

2. Did you find that your were more involved in one type of communication?

I would say yes. People may like communication type depending on their interest and skill set. So according to me even I have involved in my life with one set of communication and I am trying to use it more.

3. Which one(s) is/are most involved?

So it differs from people to people. I like verbal communication, because I am good at speaking with good tone and voice. Also, I am attracted towards visual communication because one picture will talk more than what an essay would communicate.
