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.
Program to Swap Elements Using Call by Reference #include <stdio.h> void cyclicSwap(int *a, int *b, int *c); int main() { int a, b, c; printf("Enter a, b and c respectively: "); scanf("%d %d %d", &a, &b, &c); printf("Value before swapping:\n"); printf("a = %d...
In the C programming, app we get learn about C programming in general, how to use C program to swap two numbers, C program to find ASCII, C program to print Lowercase/Uppercase, and so much more. FEATURES OF THE APP: • The C programming language app has a very user-friendly inter...
aConsider the C program in Figure 7.1. It consists of two source files,main.c and swap.c. Function main() calls swap, which swaps the two elements in the external global array buf. Granted, this is a strange way to swap two numbers, but it will serve as a small running example ...

11.Write a program in C to swap elements using call by reference. Test Data : Input the value of 1st element : 5 Input the value of 2nd element : 6 Input the value of 3rd element : 7 Expected Output: The value before swapping are : ...
Program #include main() { int x, y, t; printf("Please input 2 numbers: "); scanf("%d%d", &x, &y); printf("Before swap, the 2 numbers are: %d, %d\n", x, y); t=x; x=y; y=t; printf("After swap, the 2 numbers are: %d, %d\n", x, y); } Output Please input ...
