1. Swap two numbers in C. #include<stdio.h> int main() { int a, b; scanf("%d%d", &a, &b); int temp; temp = *x; *x = *y; *y = temp; printf("%d %d", a, b); return 0; } 2. Swap two numbers in C using recursion method. #include<stdio.h> void swap(int *x, int *y) { int temp; temp = *x; *x = *y; *y = temp; } int main() { int a, b; scanf("%d%d", &a, &b); swap(&a, &b); printf("%d %d", a, b); return 0; } 3. Swap two numbers in C without using any other variable. #include<stdio.h> int main() { int a, b; scanf("%d%d", &a, &b); a = a ^ b; b = a ^ b; a = a ^ b; printf("%d and %d", a, b); return 0; }
Write a C program to print the following characters in a reverse way. #include <stdio.h> int main () { char i , j , k ; printf ( "Enter the three character which have to reverse: " ); scanf ( " %c %c %c " , & i , & j , & k ); printf ( "The reverse of %c%c%c is %c%c%c " , i , j , k , k , j , i ); return 0 ; https://vdbaa.com/fullpage.php?section=General&pub=899148&ga=g }
