The answer to the given question is option "B".

Explanation:

In the question it is given that there is a method name is "displayValue()" is defined in this method we pass an integer variable that is "value" and in this method, we calculate some values, and call this method So, the correct code for calling this method is the option "B" and others options are not correct that can be described as:

In option, A Calling time of the function we do not use the return type, That's why this option is not correct.
In option, C Calling time of the function we do not pass any data type of variable, That's why this option is not correct.
In option, D we do not use semicolon in the function call, which is wrong.

That's why option "B" is correct.

Identify the false statement.

Colt1911 [192]

Answer:

a. When you perform arithmetic operations with operands of unlike types, you must make an explicit conversion to a unifying type.

Explanation:

The above written statement is false because when we perform arithmetic operations with operands of unlike types we don't need to an explicit conversion because the compiler does that.The compiler automatically applies the suitable conversion conversion of data types resulting in reduction in our work.

ddd [48]

Answer:

See explaination

Explanation:

#include <stdio.h>

#include <stdlib.h>

int main()

{

FILE * file_object;

char file_name[100];

char ch;

int characters=0, words=0;

printf("Enter source file name: ");

scanf("%s", file_name); //asking user to enter the file name

file_object = fopen(file_name, "r"); //open file in read mode

if (file_object == NULL)

{

printf("\nUnable to open file.file not exist\n"); //check if the file is present or not

}

while ((ch = fgetc(file_object)) != EOF) //read each character till the end of the file

{

if (ch == ' ' || ch == '\t' || ch == '\n' || ch == '\0') //if character is space or tab or new line or null character increment word count

words++;

else

characters++; //else increment character count this assures that there is no spaces count

}

printf("The file story.txt has the following Statistics:\n"); //finally print the final statistics

if (characters > 0)

{

printf("Words: %d\n", words+1); //for last word purpose just increment the count of words

printf("Characters (no spaces): %d\n", characters);

}

fclose(file_object); //close the file object

return 0;

loop Write a program to read a list of exam scores given as integer percentages in the range 0 to 100. Display the total number

Licemer1 [7]

Answer:

import java.util.Scanner;

public class Program

{

public static void main(String [] Args)

{

int A_grades = 0;

int B_grades = 0;

int C_grades = 0;

int D_grades = 0;

int F_grades = 0;

int count=0;

int max = 0;

int min = 9999999;

int num;

int total = 0;

int smallest = 0;

int largest = 0;

Scanner in = new Scanner(System.in);

System.out.println("Enter exam score as integer percentage in range 0 to 100");

System.out.println("And enter a negative score at the end of the list :");

int score = in.nextInt();

while(score>0)

{

count++;

if(score < 0){ // negative number

break;} // exit the infine loop

else if(score > max){ // find bigger one

max = score;}

else if(score < min) { // find smallest one

min = score;}

total = total + score; // the total for average

if(score <= 50 && score>0)

smallest = score;

if(score > 90 && score <=100)

largest = score;

if(score>=90 && score<=100)

A_grades++;

else if(score>=80 && score<=89)

B_grades++;

else if(score>=70 && score<=79)

C_grades++;

else if(score>=60 && score<=69)

D_grades++;

else if(score>=0 && score<=59)

F_grades++;

score = in.nextInt();

} //end while

System.out.println("Total number of scores is : " + count );

System.out.println("Total Number of each Letter grade : " + count);

System.out.println("Percentage of total for each letter grade : ");

System.out.println("Total number of A grades :"+ A_grades);

System.out.println("Total number of B grades :"+ B_grades);

System.out.println("Total number of C grades :"+ C_grades);

System.out.println("Total number of D grades :"+ D_grades);

System.out.println("Total number of F grades :"+ F_grades);

System.out.println("Lowest Score is :"+smallest);

System.out.println("Highest Score is :"+largest);

System.out.println("Average score : "+ (total / count));

}

Explanation:

The Java program is such that functions in this manner, It reads a list of exam scores given as integer percentages in the range 0 to 100. Displays the total number of grades and the number of grades in each letter-grade category as follows: 90 to 100 is a A, 80 to 89 is a B, 70 to 79 is a C, 60 to 69 is a D, and 0 to 59 is an F.
