C Programming
Questions related to the C Computer Programming Language. This ranges all the way from K&R to the most recent ANSI incarnations. C has become one of the most popular languages today, and has been used to write all sorts of things for nearly all of the modern operating systems and applications. It it a good compromise between speed, power, and complexity.

Your question makes no sense, you cannot "reinstall" programming languages (or vitamines, or letters, or Roman numbers)
Where do I find information about a J C Higgins 4xscope?
Weaver was the contractor for J C Higgins rifle scopes you are dealing with 46 to 55 year old product the 22 scopes came in two basic veriaties the delux grade rifle man very nice 4 power and simpler more basic version simply marked J C Higgins Sears and Roebuck & Co. it to is a 4 power the lesser version were sold in combination wit JCH .42 bolt action rifles 103 vendor code for Marlin the rifleman scopes were supplied with JCH model 28 30 and 33 22 semi auto and pump action rifles wich were marked 583 Sears House brand made by Sears / High standard . Sears owned High standard back then like Kenmore
What are advantages of visual c plus plus?
Well, there are really no disadvantages. If you are just starting programming, I would recommend using Visual Basic 2008. It is extremely easy to learn, and endless possiblities as far as making your program goes. The download link is right here: http://www.microsoft.com/express/vb/Default.aspx#webInstall It is free. If you are getting the registry key, make sure to use Internet Explorer.
The statement char ch equals 'z' would store in ch?
The statement char ch = 'z'; would store the character 'z' in the variable ch. This means that the variable ch would hold the value 'z'.
Is string is an predefined data types in c?
No. In C string is an array of characters terminated by a null character (a character having ascii value 0).In more high level languages like C# and Java string is a predefined data type and hence limits the operation on string by some pre-defined library functions. But C provides complete control over strings.The Following step shows declaration of a string in various methods.
char str[6] = {'h' . 'e'. 'l'. 'l'. 'o'.'\0'};
One thing you need to notice is that the size of the character array should be atleast 1 greater than the number of characters in the string for accommodating the null character.
but
char str[] = "hello";
statement appends the null character automatically and no need to specify the length of the array (of course you can specify it if you want). The compiler automatically allocates the memory according to the length of the string.
What are the three uses of void data types?
The void type has only one purpose: to specify the return type of a function that has no return value. In this case void simply means no type.
The only other usage is when used as a pointer to void (void*), which simply means a pointer type that can refer to any type of object. If the pointer is non-null, it must be cast to a specific type before it can be dereferenced.
What is Newton raphson's method in r programing?
It's a method used in Numerical Analysis to find increasingly more accurate solutions to the roots of an equation.
x1 = x0 - f(x0)/f'(x0) where f'(x0) is the derivative of f(x0)
What is the value of 201 percent 4?
201% of 4 = 8.04
On a calculator you can do this by:
201%*4 or 2 1/10 * 4 or 2.1 * 4
Does nyquist plot uses open loop closed loop or characteristic equation?
everyone knows the answer to that. if u dont u need to change ur major
What is the function of adobe premiere?
You use Adobe Premiere to create movies, edit videos, etc. Adobe Premiere is like a more professional version of iMovie, Windows Media Player, and is closely related to Final Cut.
What are the different types of agonist?
There are partial agonists and full agonists. Partial don't elicit a maximum response and have an efficacy of less than 1. Full elicit a full response and have an efficacy of 1. There are also antagonists that bind to receptors but don't elicit a response. Inverse agonists produce an opposite response.
mesh's basic salary is input through the keyboard. his dearness allowance is 40% of basic salarying , and house rent allowance is 20% of basic salaried. write a program to calculate his gross salary
Output a prompt.
Either:
Read from standard input (std::cin) to an integer.
Or:
Read a line from standard input (std::getline()) to a string.
Create a string stream (std::stringstream) to read the string.
Read from the string stream to an integer.
For each integer from 2 to half the entered integer:
If the entered integer is divisible by the current integer:
The number is not prime.
Exit the program.
The number is prime.
Exit the program.
Overload plus operator for string concatenation in coding?
#include
using std::cout;
using std::endl;
#include
using std::string;
int main()
{
string s1( "AA" );
string s2( " AAB" );
string s3;
//
cout << "\n\ns1 += s2 yields s1 = ";
s1 += s2; // test overloaded concatenation
cout << s1;
return 0;
}
C plus plus code that determine prime number?
#include <iostream.h>
main()
{
int a;
cout<<"enter a number : ";
cin>>a;
cout<<endl;
if (a%2-1)
cout<<"it is a prime number";
else
cout<<"it is not a prime number"
return 0;
}
------------------------------------------
output: enter a number : 30
it is a not a prime number
How do you give values to variable?
it depend on the programming language u use. for instance in c, just decalre the variable and equal it to the value it is to take. eg. my_age=21; /*my_age is the decared variable and 21 is the assigned value*/ //for php $my_age=21; /*my_age is the decared variable and 21 is the assigned value*/ for strings (in php)eg. $my_age="none of ur business" /*$my_age is the variable and the string "none of ur business" is the assigned value*/

What step that converts source file directives to source code program statements.?
A pre-processor will scan your code files for directives and then evaluate the conditions specified by the directive. Then depending on the evaluation of the condition it may include certain program statements and/or ignore others before handing the "modified" source code to the compiler.
What does it mean to run a program?
In computer terminology, "running a program" means copying a sequence of instructions from storage into main memory and initiating the execution or interpretation of those instructions.
Can you have two mains in a c program?
No you can't. main() is the entry point of a C program where execution starts. Only a single main() can exist in a C program. A program with 2 mains wil not even compile successfully.
1. Find out the address of the element A(4,5,2) where A is a 3-dimensional array with subscript limits 1≤ i ≤6, 1≤ j ≤7 and 0≤ k ≤4 when A is in row major addressing. Assume base address is 1000 and word size is 2.
Answer:
Array(depth,col,row) means A(4,5,2)
Address= BASE+ ((depthindex*col_size+colindex) * row_size + rowindex) * Element_Size
ADDRESS=1000+((4*7+5)*5+2)*2
(1000+((33*5)+2)*2
(1000+(167*2))
(1000+334)
