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.

Drawbacks are referred to as features that will make something less acceptable. This is commonly known as setbacks, snags, stumbling blocks and so on.
How do you merge 2 Visual C programs to get a single output?
You cannot. A C program can only have one global main function but you'd be trying to compile a program that has two main functions. The only way to merge the two programs is to modularise both programs so that neither is dependent upon their main functions. Once modularised, you can include those modules in any program. Alternatively, you can create binary libraries from the modules and link them into any program.
How do you determine which is outer loop or inner loop of the Baltimore beltway?
The outer loop goes counter clockwise, while the inner loop goes clockwise. For example, if you're driving from Fairfax, VA to Washington, DC you're going on the inner loop, and on the way back you're taking the outer loop.
What are the differences between broadside array and end fire array?
end fire array
A combination of identical and equally spaced antenna that radiate along the axis of the axis of the antenna array is known as an end fire array.
the elements are fed with a current of equal magnitude but opposite in phase.due to this variation in phase ,the radiation obtained is unidirectional.
broadside array
when the maximum radiation of an array is directed normal to the axis of array it is known as broadside array.
in a broadside array combination a number of identical antennas are set up along a line drawn perpendicular to their respective axis.
What is the term for a group of one or more C statements enclosed in braces?
The term for a group of one or more C statements that are enclosed in braces is called a command block. A command block is a block that is made with the intent to support adventure mode.
Write a program in C to check whether a given number is odd or even using switch statement?
#include<stdio.h>
#include<conio.h>
void main()
{ int n;
printf("please enter number \n");
scanf("%d",n);
switch(n%2)
{
case 0 : printf("even");
break;
case 1 :
case -1 :
printf("odd");
}
getch();
}

The expression in the switch statement is evaluated. The result of this evaluation is then compared with each case statement in turn until a matching case is found, which then forces a jump to the appropriate case. Execution then continues from that point until a break, return or goto statement is encountered, or execution falls through the switch statement.
What is the maximum length allowed in difining a c variable?
In order to claim compliance with ANSI C standards, the minimum maximum for internal identifiers and macros is 63 characters, and external identifiers is 31 characters. Vendors are encouraged to avoid imposing a maximum value whenever possible.
GCD stands for the Greatest Common Denominator.
No it doesn't. GCD is the greatest common divisor, also known as the greatest common factor.

Write a c program to find the product of two numbers without using operator?

printf("enter a value for a and b");
scanf("%d%d",&a,&b);

How do you input float into an array?
#include
using std::cin;
using std::cout;
using std::endl;
int main()
{
int myArraySize = 10;
//array of type float declaration and initialization of all elements to zero
float myArray[myArraySize] = {0.0f};
cout << endl << "Enter element of your array (of type float)..." << endl;
for(int i(0); i < myArraySize; i++)
{
cout << endl << "Enter " << (i + 1) << " element: ";
cin >> myArray[i];
}
cout << endl << "You have entered: " << endl;
for(int i(0); i < myArraySize; i++)
{
cout << (i + 1) << " element: " << myArray[i];
}
system("PAUSE");
return 0;
}
Write any small program that will compile in C but not in C plus plus?
#include
int main (void)
{
char new [3] = "NEW";
printf ("new='%.3s'\n", new);
return 0;
}
in C++:
int main (void)
{
char newstr [4] = "NEW";
printf ("new='%.3s'\n", newstr);
return 0;
}
Describe a chicken using a programming language?
chicken is a function which takes argument as grain type and returns egg.
egg chicken(grain x);
less than zero, greater than the requred return
Find the highest and lowest element from a linked list?
To find the highest and lowest elements in a linked list, iterate the list and detect the highest and lowest elements. Details omitted ...
list *head; /* pointer to first element */
list *temp; /* temp pointer
list *high = null; /* pointer to high element */
list *low = null; /* pointer to low element */
for (temp=head; temp!=null; temp=temp->next) { /* iterate all elements */
if (temp == head ) { /* initial case */
high = low = temp; /* start accumulating results
} else { /* otherwise */
if (higher(temp, high) high = temp; /* choose higher */
if (lower(temp, low) low = temp; /* choose lower */
}
}
To evaluate a variable you must values for the variable and then calculate the result?
No. To evaluate a variable, you simply take its value. When you assign a value to a variable, the evaluation of that operation is the value of the variable after assignment. There is no calculation required to evaluate a variable, unless that calculation is part of the right-hand operand of an assignment operation, in which case the calculation is evaluated first and the result of that evaluation (the value) is then assigned to the variable which is then evaluated.
How is the old stack pointer value recovered on a function return?
If your stack grows bottom-up, it's decremented when you leave a function; if the stack grows top-down, the stack pointer is incremented.
