Construct a flowchart based on this code and write its equivalent algorithms.

#include <stdio.h>

int main()
{
int x,y;
float result;
char ch; //to store operator choice

printf("Enter first number: ");
scanf("%d",&x);
printf("Enter second number: ");
scanf("%d",&y);

printf("Choose operation to perform (+,-,*,/): ");
scanf(" %c",&ch);

result=0;
switch(ch)

case '-':
result=x-y;

FLOW CHART


The code:

#include <stdio.h>

int main()
{
int x,y;
float result;
char ch; //to store operator choice

printf("Enter first number: ");
scanf("%d",&x);
printf("Enter second number: ");
scanf("%d",&y);

printf("Choose operation to perform (+,-,*,/): ");
scanf(" %c",&ch);

result=0;
switch(ch)
{
case '+':
result=x+y;
break;

case '-':
result=x-y;
break;

case '*':
result=x*y;
break;

case '/':
result=(float)x/(float)y;
break;

case '%':
result=x%y;
break;
default:
printf("Invalid operation.\n");
}

printf("Result: %d %c %d = %.2f\n",x,ch,y,result);
// Directly print the number with .2f precision
printf("\n\n Input new number to try again/ n to exit):");
getchar();
ch=getchar();
if (ch !='n')
   {
       return main();
   }
   else
   {
       printf("\n\n Have a Nice Day!");
   }
   return 0;
}
