Swap two numbers using call by address in c
SpletSince address of variable a and b are passed to swap () method, we take 2 pointer variables *x and *y. Pointer variable x holds the address of a and pointer variable y holds the address of b. Using below logic we swap the values present at address a ( or x ) and b ( or y ). temp = *x; *x = *y; *y = temp; SpletWe are using a function called swap().This function basically swaps two numbers, how we normally take a temporary variable in C to swap 2 nos. Dry Run of the Program. Take 2 …

Splet27. mar. 2024 · In C, a function specifies the modes of parameter passing to it. There are two ways to specify function calls: call by value and call by reference in C. In call by value, the function parameters gets the copy of actual parameters which means changes made in function parameters did not reflect in actual parameters. SpletWe are asking the user to input 2 variables and store the variable into the pointer. Finally use the pointers variable along with the temp variable to swap the number. We have defined a function swapNum () to swap the numbers by using pointer. #include . void swapNum (int * num1, int * num2);
SpletThis example contains two different techniques to swap numbers in C programming.

Above is the source code for C++ Program to Swap two ...
SpletLets write a C program to swap 2 numbers using function/method. When we call a function and pass the actual value it’s called as Call by Value method. If we pass the reference or the address of the variable while calling the function, then it’s called Call by Reference.. In today’s video tutorial we’ll be showing you the concept of Call By Value. SpletSo, the swap function should not be done using a pass-by-value. If you want to add two numbers and return the result then in such cases you can use pass by value. But here it is …
