Answer:
Program is in C++
Explanation:
C++ Code:
#include <iostream>
#include <cctype>
using namespace std;
int main(){
char ch;
do{
cout<<"Enter Character: ";
cin>>ch;
if (isupper(ch)){
cout<<"OK"<<"\n";
}
}
while(ch!='!');
return 0;
}

Code Explanation
First execute a do while loop as we want user to enter at least first character to check whether its upper case or not. If user enters exclamation character then this loop will terminate along with the program.
To check whether the entered character is upper case or not we will be using isupper(ch) method defined in cctype library.
If the character is upper case then if condition will show Ok by printing it using cout and this program will show nothing if the character is not upper case.
Sample Output
Enter Character: A
OK
Enter Character: b
Enter Character: c
Enter Character: d
Enter Character: E
OK
Enter Character: G
OK
Enter Character: F
OK
Enter Character: !
Answer:
123456
Explanation:
When an integer value is added to a string value the resulting value is a string.+ operator is used for both numeric additions and string addition also knows as string concatenation. In addition when one operand of the equation is a string the program interprets all values as string. As system is interpreting all values as a string it will apply a string addition method instead of mathematical addition.So here A is a string and B is an integer value. when we add A and B system will treat B aslo as a string, upon addition the result will be String concatenating both A and B to a single string.Hence the result of A+B will be
A+B = 123456
As WriteLine method takes string as Input it will just write the resulting string to file
The answer is A. For instance, to use the sum function, you would need to =SUM()
The equivalent of film speed in a digital camera is going to be sensitivity. This will make the correct answer B.
Answer:
The program in C++ is as follows:
#include <iostream>
#include <vector>
using namespace std;
int main(){
vector<int> nums;
int num;
cin>>num;
while(num != -1){
nums.push_back(num);
cin>>num; }
for (auto i = nums.begin(); i != nums.end(); ++i){
cout << *i <<endl; }
return 0;
}
Explanation:
This declares the vector
vector<int> nums;
This declares an integer variable for each input
int num;
This gets the first input
cin>>num;
This loop is repeated until user enters -1
while(num != -1){
Saves user input into the vector
nums.push_back(num);
Get another input from the user
cin>>num; }
The following iteration print the vector elements
<em> for (auto i = nums.begin(); i != nums.end(); ++i){
</em>
<em> cout << *i <<endl; }
</em>
