Answer:
Option(a) i.e "true" is the correct answer for the given question.
Explanation:
The select statement is used for fetching the record in the database. Select is the Data manipulation command. The given query gives all the records where id=5 from the table publisher in the table format.After executing of query the user can verify that the field is updated or not in the table.
So the given statement is "true".
Answer:
A varying infrastructure.
Explanation:
The competitive pressure it creates for multinational companies in the industry is one of difference in infrastructure because different technical standards are found in different parts of the world.
For instance, A technical standard known as Global Systems for Mobile (GSM) is common in Europe, and an alternative standard, Code Division Multiple Access (CDMA), is more common in the United States and parts of Asia.
Consequently, equipment designed for GSM will not work on a CDMA network and vice versa as a result of varying infrastructure, so companies would be innovative in order to improve on their products.
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;
}
Answer:
D. method, class, generalization/specialization
Explanation:
The Cohesion is said to be the level to what an element of a module is related to others. Generally, the cohesion can be understood as an internal adhesive that holds together the modules. If the software is good then it is going to have high cohesion. Method and class are type of cohesion, as they hold the modules together. And generalization/specialization also is a general type of cohesion as generalization tracks the common features among the class, and binds them into one superclass. However, the specialization means creating subclasses out of the classes, and which is the meaning of the specialization. In an ideal situation, there should be high cohesion or single responsibility. However, in the case of inheritance, there can be multiple responsibilities. And hence composition like a generalization, specialization, association, aggregation are used to make use of the composition for reuse rather than inheritance. Have you seen language supporting multiple inheritances. You will never see it though there is some way. And its never allowed to ensure high cohesion. And hence three general types of cohesion are method, class and generalization/specialization. And this is option D.
