Question

Write a program whose input is two integers and whose output is the two integers swapped.

Write in C language

7.3 LAB: Swapping variables Write a program whose input is two integers and whose output is the two integers swapped. Ex: If the input is: 38 then the output is: 83 Your program must define and call a function. SwapValues returns the two values in swapped order. void SwapValues(int* userVali, int* userVal2) ACRIVITY 7.3.1: LAB: Swapping variables 0/10 ] main.c Load default template... 1 #include <stdio.h> 3 /* Define your function here */ 4 void SwapValues(int *userVali, int *userval2) 5 { int temp=uservall; uservall=userval2; userval2=temp; 9 } 10 int main(void) { 11 int *uservall, userval2; 12 /* Type your code here. Your code must call the function. */ 13 scanf("%d", &uservall); 14 scanf("%d", &userval2); 15 SwapValues(&userVali, &userval2); 16 printf("%d %d\n", "userVall *userval2); 17 return 0; 18 }

Answer 1

C Code:

#include <stdio.h>
#include <stdlib.h>

//Function to swap variables
void SwapValues(int* userVal1, int* userVal2){
//using a temp variable
int temp=*userVal1;
//swapping
*userVal1 = *userVal2;
*userVal2 = temp;
}
int main()
{
//declaring the variables
int userVal1, userVal2;
//getting the variables from the user
scanf("%d", &userVal1);
scanf("%d", &userVal2);
//calling the swap function
SwapValues(&userVal1, &userVal2);
//printing the values after swapping
printf("%d %d", userVal1, userVal2);
return 0;
}

Sample Output:

3 8
8 3
