The required c program is given below
/*Swapping(interchange) the two entered numbers*/
#include<stdio.h>
main()
{
/*Without using third variable*/
int a,b,t;
printf("Enter a:");
scanf("%d",&a);
printf("Enter b:");
scanf("%d",&b);
a=a+b;
b=a-b;
a=a-b;
printf("\n After swapping without using third variable");
printf("\na=%d\nb=%d",a,b);
}
To swap two numbers without using a temporary variable, use the bitwise exclusive or function...
A^=B;
B^=A;
A^=B;
yes we can run java program without using main. we can run program by declaring the variable static..
Impossible to say without seeing the program's source.
It is very easy. The program begins here..... /*Program to sum and print numbers without creating variables*/ #include<stdio.h> main() { clrscr(); printf("%d+%d=%d",5,2,5+2); getch(); } /*Program ends here*/ Now just by changing the numbers in the "printf" statement we can add, subtract, multiply and divide the numbers without using variables. Hence the problem is solved..........
If you are talking about a class in Java, a variable encapsulated by a class is called an instance variable b/c everytime you create an object with that class, each object has its own set of the variables declared.
int a,b; a=a+b; b=a-b; a=a-b; that's it simple
Any number variable is extends the Number in java and it already implemented Comparable interface. So when you have a list of numbers, just use Arrays.sort().
You can use Alt codes, which are codes that can be entered by holding down the Alt key as you enter numbers on the numpad.

Yes. int a, b; a= 2; b= 3; a= a+b;

To swap two variables without using a third variable, use exclusive or manipulation... a ^= b; b ^= a; a ^= b;
Just the number, for example: 7x the variable is 7. The variable is the number without the variable(x,y,z, etc.)
There are three primary algorithms to exchange the values of two variables. Exchange with Temporary Variable temp = a; a = b; b = temp; Exchange Without Temporary Variable Using Exclusive Or a = a ^ b; b = b ^ a; a = a ^ b; Exchange Without Temporary Variable Using Arithmetic a = a + b; b = b - a; a = a - b;
If a term doesn't have a variable , then its probably a constant.
