Answer: That due to the specific tasks that needs to be accomplished by each program to make an all encompassing program would be inefficient and full of bugs
Explanation: try to do something along those lines ex why would MySQL be used to check your essay for grammar the tasks are on opposite spectrums
Answer:
1. Where,
2. From
Explanation:
In SQL query language when working on a database, a user can use certain clauses to carry out some functions.
Hence, The WHERE clause allows us to select only those rows in the result relation of the FROM clause that satisfy a specified predicate.
This is because the "Where clause" selects the rows on a particular condition. While the "From clause" gives the relation which involves the operation.
Answer:
You may use a different variable type for input in order to process the data appropriately and may use a different variable type to accommodate your program.
Explanation:
Your input may have to be different then output varying on what data you are processing.
For example, just like the last question you asked about calculating the area of the rectangle, your input MUST be converted to a different a numerical data type (i.e int or float) in order to do the math.
Based on your last question, if we didn't convert your input into a string your results wouldn't add the numbers together but only concatenate them. If I typed 3 & 5 as length & width, I would get 35 instead of 15.
Now another example is using functions (or methods whatever you want to call them), your input can be one thing and outputs another.
Let's say I want a function to tell me if I am smart. The way I want it to determine if its smart is by inputting my GPA into it, which is a numerical value. So the function would look something like this:
<u>Code (Python)</u>
def IsSmart(gpa):
if (gpa >= 4):
return True
else
return False
As you can see I am inputting a numerical value and it is outputting a boolean value. I can use this in a if else chain to spit out an output to the user.
Answer:
#include <iostream>
using namespace std;
struct StudentType{
string studentName;
int studentId;
}
int n;
char answer[20];
int main(){
cout<< "Enter the size of the array: ";
cin >> n;
StudentType *student = new StudentType(n);
for (int i = 0; i < n; i++){
int name;
int number;
cin>> name;
cin >> number;
student[i].studentName = name;
student[i].studentId = number;
}
for (int i = 0; i < 20; i++){
cout<< "Enter answers: ";
cin >> ans;
answer[i] = ans;
}
}
Explanation:
The C++ source code has three global variables namely, answer which is an array of character data type, StudentType which is a structure data type and the integer variable n. The main function declares and initializes the dynamic-spaced student array of the structure datatype with the n variable.
