Write a C program to swap two numbers without using temporary variable.
int main() {
int num1, num2;
/* get the first input from user */
printf("Enter your first data:");
scanf("%d", &num1);
/* get second input from user */
printf("Enter your second data:");
scanf("%d", &num2);
printf("Data before swapping:\n");
printf("num1: %d num2: %d\n", num1, num2);
/* swap the given data */
num1 = num1 + num2;
num2 = num1 - num2;
num1 = num1 - num2;
/* print the results */
printf("Data after swapping:\n");
printf("num1: %d num2: %d\n", num1, num2);
return 0;
}
Output:
jp@jp-VirtualBox:~/$ ./a.out
Enter your first data:100
Enter your second data:200
Data before swapping:
num1: 100 num2: 200
Data after swapping:
num1: 200 num2: 100
Enter your first data:100
Enter your second data:200
Data before swapping:
num1: 100 num2: 200
Data after swapping:
num1: 200 num2: 100
