#include<stdio.h>
#include<conio.h>
void main()

int a;
clrsscr();
printf("enter the value of a\n");
scanf("%d",&a);
if(a%2==0)

Answer 1

why would you place getch(); at the end?

Answer 2

Shiddhat Kumar this code is written for a proprietary C development environment (historically, it was Borland Turbo C). It has nonstandard elements such as: conio.h, clrscr(), getch(), and void main() instead of int main()

If you want it to run on Sololearn then simply comment out or delete the nonstandard lines and declare int main().

#include <stdio.h>
//#include <conio.h>
//void main()
int main()
{
int a;
//clrscr();
.
.
.
//getch();
}

Answer 3

Infinity the reason for the getch() at the end is that it prevents the MSDOS window from closing instantly after execution. It gives a pause for input so you may observe the results.
