Swap Numbers in a Cyclic Manner in C
C Program to Swap Numbers in a Cyclic Order
In this page, we have provided codes and algorithms to swap numbers in a cyclic manner in C. This includes swapping two numbers and swapping three numbers in a cyclic order.
Swap Two Numbers in a Cyclic Order in C
To swap numbers in a cyclic manner in a C program, you can use a temporary variable to store the value of one of the numbers while the other number is being assigned to it.
Step 2:- assign it the value of x
Step 3:- assign the value of y to x and the value of temp (original valueof x) to y.
Step 4:- print the swapped values of x and y
Program to Swap Two Numbers in a Cycle
#include <stdio.h>
int main() {
int x = 10;
int y = 20;
printf("Before swapping: x = %d, y = %d\n", x, y);
int temp = x;
x = y;
y = temp;
printf("After swapping: x = %d, y = %d\n", x, y);
return 0;
}
Output
Before swapping: x = 10, y = 20
After swapping: x = 20, y = 10
Swap Three Numbers in a Cyclic Order in C
It is similar to swapping two numbers. The only difference is that there are three temporary variables to assign the values of three numbers.
Step 2:- print these values to console using printf function.
Step 3:- define two temporary variables, temp1 and temp2 and assign them the values of x and y respectively.
Step 4:- assign the value of z to x, value of temp1 to y and temp2 to z.
Step 5:- the values of x,y and z are printed with the values being rotated in a cyclic manner.

#include <stdio.h>
int main() {
int x = 10;
int y = 20;
int z = 30;
printf("Before swapping: x = %d, y = %d, z = %d\n", x, y, z);
int temp1 = x;
int temp2 = y;
x = z;
y = temp1;
z = temp2;
printf("After swapping: x = %d, y = %d, z = %d\n", x, y, z);
return 0;
}
Output
Before swapping: x = 10, y = 20, z = 30
After swapping: x = 30, y = 10, z = 20
Swap Variables of Different Types in C Program
Step 2:- define two variables x and y
Step 3:- define a variable temp of type union value and assign it the value of x.
Step 4:- Assign the value of y o x, casting it to an int first, and the value of temp.i
Step 5:- Print the values of x and y being swapped
#include <stdio.h>
union value {
int i;
float f;
char c;
};
int main() {
int x = 10;
float y = 20.5;
printf("Before swapping: x = %d, y = %f\n", x, y);
union value temp;
temp.i = x;
x = (int) y;
y = (float) temp.i;
printf("After swapping: x = %d, y = %f\n", x, y);
return 0;
}
Output
Before swapping: x = 10, y = 20.500000 After swapping: x = 20, y = 10.000000
