When possible you should advoid using what variables in a program?
Global Variables Or: variables with names longer than 128 characters.
How can you accept sum and print numbers without creating variables?
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..........
How can you devise a way to interchange two variables A and B without using a third variable or register using Exclusive OR?
A = A xor B B = A xor B A = A xor B in C... A^=B; B^=A; A^=B;
What is the Algorithm for exchanging values of two variables?
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;
What is program in c to swap entered two numbers without using third variable?
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 variables without using a third variable, use exclusive or manipulation... a ^= b; b ^= a; a ^= b;

How do you write a program in C to swap two variables using the third variable?
Consider the following declarations:int x = 0;int y = 1;In order to swap the values, we need to use a temporary variable:int t = x;x = y;y = t;However, it is possible to swap the values without using a third variable:x ^= y ^= x ^= y;
How do you write a program in C to swap two variables without using the third one - 46k?
int a = 5; int b = 10; a = a + b; // a = 5 + 10 = 15 b = a - b; // b = 15 - 10 = 5 a = a - b; // a = 15 - 5 = 10
