C++ Programming
Questions related to the C++ Computer Programming Language. This ranges all the way from K&R C to the most recent ANSI incarnations of C++, including advanced topics such as Object Oriented Design and Programming, Standard Template Library, and Exceptions. C++ has become one of the most popular languages today, and has been used to write all sort of things for nearly all of the modern operating systems and applications." It it a good compromise between speed, advanced power, and complexity.

Where did the members of the merchants class work?
Members of the merchant class typically worked in urban areas, engaging in trade and commerce. They operated businesses such as shops, markets, and warehouses, selling goods ranging from local products to imported items. Many merchants also participated in trade networks, facilitating the exchange of goods across regions and countries. Their work contributed significantly to the economic development of cities and the expansion of markets.
List two reasons why STD are considered epidemic?
STDs are considered epidemic due to their high transmission rates and the significant public health impact they have on communities. The ease of spreading these infections, often through sexual contact, contributes to widespread outbreaks, particularly among vulnerable populations. Additionally, the lack of awareness and access to preventive measures exacerbates their prevalence, leading to increased incidence and complications associated with untreated infections.
Does pinky the porn star have a std?
I cannot provide personal health information about individuals, including public figures like adult film stars. It's important to respect people's privacy and avoid spreading unverified information. For accurate health information regarding sexually transmitted infections, consulting a healthcare professional is recommended.
STD Testing is for testing specific sexually transmitted diseases such as Chlamydia and gonorrhea.
Chlamydia and gonorrhea screening is done either through a urine test or through a swab inside the penis in men or from the cervix in women. The sample is then analyzed in a laboratory.
Screening is important, because if you don't have signs or symptoms, you can be unaware that you have either infection.
Oh, dude, creating a flowchart for that is like making a peanut butter and jelly sandwich - easy peasy. You just gotta start with a diamond shape for the decision-making process, then add rectangles for the input/output and calculations. Like, you'll have one box for accepting the number, another for calculating the product of the integers, and a final one for printing the result. It's like drawing a map to the land of math!
What is the binary number for 128 64 32 16 8 4 2 1?
In binary numbers...
1 = 1
2 = 10
4 = 100
8 = 1000
16 = 10000
32 = 100000
64 = 1000000
128 = 10000000
To create a class "Mat" of size m x n, you would define a class with attributes for the number of rows (m) and columns (n), and a 2D array to store the matrix elements. For addition, you would need to check that the dimensions of the two matrices being added are the same, then add corresponding elements. For subtraction, you would similarly check dimensions and subtract corresponding elements. For multiplication, you would ensure that the number of columns in the first matrix matches the number of rows in the second matrix, then perform matrix multiplication to get the resulting matrix.
Well, isn't that just a happy little math problem! If A is less than B and B plus C equals 10, then it must be true that A plus C is less than 10. Just remember, in the world of numbers, everything adds up beautifully in the end.
Difference between ios function and manipulators?
1. ios functions returns value while manipulators does not.
2.we can not create own ios functions while we can create our own manipulators.
3.ios functions are single and not possible to be combined while manipulators are possible to be applied in chain.
4.ios function needs <iostream> while manipulators needs <iomanip>
5.ios functions are member functions while manipulators are non-member functions.

How do you reverse a 5 digit number in c plus plus?
It really does not matter how many digits there are, the principal is exactly the same. The following function is the most efficient way to reverse any whole number in the range -2,147,483,648 to 2,147,483,647, inclusive (assuming a 32-bit integer). To increase the range, create separate functions to cater for 64-bit and 128-bit integers. Converting the number to a string and reversing the string is also an option (see previous answer, below), however it is by far the least efficient method of reversing a whole number.
int RevNum( int num )
{
const int base = 10;
int remain = 0;
int result = 0;
do
{
remain = num % base;
result *= base;
result += remain;
} while( num /= base);
return( result );
}
Previous AnswerThis is assuming the number is decimal.
There are several approaches to the problem, depending on the resources you have available or wish to use to solve it.
One way to achieve this is to isolate the digits through modulo division and the remultiply them in the desired order:
rev = ((original % 10) * 10000) + (((original / 10) % 10) * 1000) + (((original / 100) % 10) * 100) + (((original / 1000) % 10) * 10) + (original / 10000);
An alternative that doesn't look so messy:
int temp = original;
int rev = 0;
for (int i=0;i<5;i++)
{
rev = (rev * 10) + (temp % 10);
temp /= 10;
}
If you're employing strings, then another novel way can be used.
#include
#include
#include
char numstring[6];
snprintf(numstring,5,"%d",original);
strrev(numstring);
rev = atoi(numstring);
Note that these are just examples of how it can be achieved. There is no standard function to reverse a decimal number in C or C++, so it's up to you to find or code a solution for yourself.
Explain control instructions in c plus plus?
Control instructions are instructions that alter the flow of execution. In C++ this include if, if-else statements, switch-case statements and the conditional ternary operator (?:), as well as loop structures (for, while, do-while) and procedural goto statements.
What is the difference between the statement a plus plus and plus plus a?
This is used in languages such as C, C++ and Java. The difference is when the statement is executed. If placed before the variable, the increment is done before other operations, otherwise, after them. This is best shown in an example.
a + b++ means to add first, then to increment the variable b.
a + ++b means to increment b first, then to do the addition.
Similarly, in a = b++, b is copied to a, and then increment; while in a = ++b, variable b is incremented before being copied.
To obtain the last whole digit of a number, use the modulo (%) of the number and 10. The modulo evaluates to the remainder after division. Thus 15%10 returns 5 because 15 divided by 10 is 1 remainder 5. Therefore the last digit of any integer, n, is therefore n%10. The same trick can be used to find the last digit for any base, where n is a base 10 integer. Thus n%8 will return the last octal digit, while n%16 will return the last hexadecimal digit.
The chemical equation representing the reaction of magnesium (Mg) with oxygen (O2) to form magnesium oxide is: 2Mg + O2 → 2MgO The "c" in your equation does not have a clear designation in this context.
What is the difference between static binding and run time binding?
Static binding occurs at compile time and refers to the linking of a method call to the method definition. Runtime binding occurs at runtime and refers to the actual method implementation that is executed based on the object type at runtime.
What is difference between Bac arrays and DNA arrays?
BAC arrays use bacterial artificial chromosomes to clone DNA fragments for analysis, while DNA arrays use immobilized DNA sequences for high-throughput analysis of gene expression or genotyping. BAC arrays are useful for large DNA fragments, while DNA arrays are more suitable for analyzing gene expression profiles or detecting DNA variations.
