Question

How do you write the code for a program to compare three variable int's in a void function with if/else statements only. The program takes 3 integers as input and outputs the integers sorted from least to greatest. Cannot use && or ||, only basic nested if/else statements. Please give details.

Dear Student,

below i written the C code as per the requirement.

Please note the below program has been tested on ubuntu 16.04 system and compiled using gcc compiler. This code will also work on other iDe;'

-----------------------------------------------------------------------------------------------------------------------------------

Program:

-----------------------------------------------------------------------------------------------------------------------------------

#include<stdio.h>

void swap(int *x, int *y);

void compare(int a, int b,int c)

{

if (a > c)
{

swap(&a, &c);

}

if (a > b)
{

swap(&a, &b);

}

if (b > c)
{
swap(&b, &c);
}

printf("Numbers before sorting = %d %d %d\n", a, b, c);

}

void swap(int *x, int *y)

{

int temp;

temp = *x;

*x = *y;

*y = temp;

}

int main()

{

int a, b, c;

printf("Enter three numbers: ");

scanf("%d %d %d", &a, &b, &c);

printf("Numbers before sorting = %d %d %d\n", a, b, c);

compare(a, b, c);

return 0;

}
