In this C Programming example, we will discuss how to swap two numbers using the pointers in C and also discuss the execution and pseudocode in detail.
The addresses of these numbers are passed to the cyclicSwap() function. cyclicSwap(&a, &b, &c); In the function definition of cyclicSwap(), we have assigned these addresses to pointers. cyclicSwap(int *n1, int *n2, int *n3) { ... } When n1, n2 and n3 inside cyclicSwap(...
Write a program in C to swap two numbers using a function. C programming: swapping two variables Swapping two variables refers to mutually exchanging the values of the variables. Generally, this is done with the data in memory. The simplest method to swap two variables is to use a third te...
C program to compare two strings using pointers C program to create and print array of strings C program to capitalize first character of each word in a string C program to find the frequency of a character in a string C program to read a string and print the length of the each word ...
Example 2: Swapping two numbers using Pointers This is one of the most popular example that shows how to swap numbers using call by reference. Try this program without pointers, you would see that the numbers are not swapped. The reason is same that we have seen above in the first example...
1. Start the program. 2. Take two numbers as input. 3. Declare a function to swap two numbers which takes a pointer to a variable as parameter i.e any changes to variable in the function will be reflected everywhere. 4. Swap the two numbers inside the function using de-reference ...
