Answer:
The correct option : b. new GridLayout(4,3)
Explanation:
The total number of rows are 4 and total number of columns are 3.
So the total keys can be added is 4*3=12. This is suited for telephone keypad.
Answer:
The answers to 1st question and part 2A is given. However, the 2B is not given complete and thus cannot be answered.
Explanation:
UNION is a keyword used in C Language to have a commonly shared memory that can be used by multiple elements. It is a data-type that allows different data types to use the same shared memory location.
Importance: If you want to minimize the use of memory by sharing it between different datatype variables, then use UNION. For Ex. Let's suppose I want to use 2 variables a and b of type char and int respectively. Now, suppose int takes memory space of 2 bytes and char takes 1 byte then the total amount of memory needed = 2 + 1 = 3 Bytes. But, we want to first make use of a, and once done, we want to declare variable b. We can limit the memory use by declaring a memory space of 2 bytes (max of a and b). First, we can use this space to store the int variable and when done with it, we can use it to store the char variable.
PART 2A
typedef struct{
int partNum;
char partName[25];
} partin;
#define Partin partin

Answer:
#include <iostream>
#include <vector>
using namespace std;
void calGPA();
vector<int> g;
vector<int> h;
int main(){
char pushMore = 'y';
int fg, fh;
for (;;){
if (pushMore == 'n'){
break;
} else{
cout<< "Enter integer for grade: ";
cin>> fg;
cout<< "Enter integer for credit hours: ";
cin>> fh;
g.push_back(fg);
h.push_back(fh);
cout<< "Do you want to add more grade and credit hours? y/n: ";
cin>> pushMore;
}
}
calGPA();
}
void calGPA(){
double total = 0, GPA;
for (int i = 0; i < g.size(); ++i) {
total += g.at(i) * h.at(i) ;
}
cout<< "The GPA is : "<< total/g.size();
}
Explanation:
The C++ source code above defines two vectors 'g' and 'h'. The latter holds the grades of a student while the former holds the credit hours for the subject taken. The void 'calGPA' function calculates and prints the student's GPA.
